“Gender and Migration” is encyclopedic in nature and an essential resource for anyone interested in immigration, gender or both. — Nancy Foner, Hunter College
Gender roles, relations, and ideologies are major aspects of migration. In a timely book on the subject, SMU anthropologist Caroline B. Brettell argues that understanding gender relations is vital to a full and more nuanced explanation of both the causes and the consequences of migration, in the past and at present.
Gender and Migration (Polity, 2016) explores gendered labor markets, laws and policies, and the transnational model of migration. With that, Brettell tackles a variety of issues such as how gender shapes the roles that men and women play in the construction of immigrant family and community life, debates concerning transnational motherhood, and how gender structures the immigrant experience for men and women more broadly.
“I have been working on the intersections of gender and migration since graduate school days and beginning with my dissertation research on Portuguese migrant women in France,” Brettell said. “Turning the lens of gender on population mobility reveals dimensions that might not otherwise be visible.”
Brettell is Ruth Collins Altshuler Professor of Anthropology and director of the Interdisciplinary Institute at Southern Methodist University.
The book will appeal to students and scholars of immigration, race and ethnicity, and gender studies and offers a definitive guide to the key conceptual issues surrounding gender and migration.
Anthropologist Brettell is an internationally recognized immigration expert on how the technology boom affects immigration, trends of new immigration gateway cities such as Dallas, Atlanta and Minneapolis and the challenges of women immigrants. Her research focus includes anthropology of Europe; migration and ethnicity; folk religion; and cross-cultural perspectives on gender.
An immigrant herself, Brettell was born in Canada and became a U.S. citizen in 1993.
Using ancient DNA, researchers have created a unique picture of how a prehistoric migration route evolved over thousands of years – revealing that it could not have been used by the first people to enter the Americas, as traditionally thought.
The established theory about how Ice Age peoples first reached the present-day United States has been challenged by an unprecedented study that concludes that their supposed entry route was “biologically unviable.”
The first people to reach the Americas crossed via an ancient land bridge between Siberia and Alaska but then, according to conventional wisdom, had to wait until two huge ice sheets that covered what is now Canada started to recede, creating the so-called “ice-free corridor” that enabled them to move south.
In a new study published in the journal Nature, however, an international team of researchers used ancient DNA extracted from a crucial pinch-point within this corridor to investigate how its ecosystem evolved as the glaciers began to retreat.
They created a comprehensive picture showing how and when different flora and fauna emerged so the once ice-covered landscape became a viable passageway. No prehistoric reconstruction project like this has ever been attempted before.

The researchers conclude that while people may well have travelled this corridor after about 12,600 years ago, it would have been impassable earlier than that, as the corridor lacked crucial resources, such as wood for fuel and tools, as well as game animals essential to the hunter-gatherer lifestyle.
If this is true, then it means that the first Americans, who were present south of the ice sheets long before 12,600 years ago, must have made the journey south by another route. The study’s authors suggest that they probably migrated along the Pacific coast.
Who these people were is still widely disputed. Archaeologists agree, however, that early inhabitants of the modern-day contiguous United States included the so-called “Clovis” culture, which first appear in the archaeological record over 13,000 years ago. And the new study argues that the ice-free corridor would have been completely impassable at that time.
“There is compelling evidence that Clovis was preceded by an earlier and possibly separate population,” said archaeologist and co-author on the study David J. Meltzer, Henderson-Morrison Professor of Prehistory in the Department of Anthropology at Southern Methodist University, Dallas. “But either way, the first people to reach the Americas in Ice Age times would have found the corridor itself impassable.”
The ice-free corridor simply opened up too late to be the principal entry route
The research was led by evolutionary geneticist Eske Willerslev, a Fellow of St John’s College, University of Cambridge, who also holds posts at the Centre for GeoGenetics, University of Copenhagen, and the Wellcome Sanger Institute in Cambridge.
“The bottom line is that even though the physical corridor was open by 13,000 years ago, it was several hundred years before it was possible to use it,” Willerslev said. “That means that the first people entering what is now the U.S., Central and South America must have taken a different route. Whether you believe these people were Clovis, or someone else, they simply could not have come through the corridor, as long claimed.”
Mikkel Winther Pedersen, a doctoral student at the Centre for GeoGenetics, University of Copenhagen, who conducted the molecular analysis, added: “The ice-free corridor was long considered the principal entry route for the first Americans. Our results reveal that it simply opened up too late for that to have been possible.”
The corridor is thought to have been about 1,500 kilometers long, and emerged east of the Rocky Mountains 13,000 years ago in present-day western Canada, as two great ice sheets – the Cordilleran and Laurentide, retreated.
On paper, this fits well with the argument that Clovis people were the first to disperse across the Americas. The first evidence for this culture, which is named after distinctive stone tools found near Clovis, New Mexico, also dates from roughly the same time, although many archaeologists now believe that other people arrived earlier.
“What nobody has looked at is when the corridor became biologically viable,” Willerslev said. “When could they actually have survived the long and difficult journey through it?”
Radiocarbon dates, pollen, macrofossils and DNA revealed how ecosystem developed The conclusion reached by Willerslev and his colleagues is that the journey would have been impossible until about 12,600 years ago. Their research focused on a “bottleneck,” one of the last parts of the corridor to become ice-free, and now partly covered by Charlie Lake in British Columbia, and Spring Lake, Alberta — both part of Canada’s Peace River drainage basin.
The team gathered evidence — including radiocarbon dates, pollen, macrofossils and DNA taken from lake sediment cores — which they obtained standing on the frozen lake surface during the winter season. Willerslev’s own PhD, 13 years ago, demonstrated that it is possible to extract ancient plant and mammalian DNA from sediments, as it contains preserved molecular fossils from substances such as tissue, urine and feces.
Having acquired the DNA, the group then applied a technique termed “shotgun sequencing.”
“Instead of looking for specific pieces of DNA from individual species, we basically sequenced everything in there, from bacteria to animals,” Willerslev said. “It’s amazing what you can get out of this. We found evidence of fish, eagles, mammals and plants. It shows how effective this approach can be to reconstruct past environments.”
This approach allowed the team to see, with remarkable precision, how the bottleneck’s ecosystem developed. Crucially, it showed that before about 12,600 years ago, there were no plants, nor animals, in the corridor, meaning that humans passing through it would not have had resources vital to survive.
Clovis could not have travelled through ice-free corridor as previously believed Around 12,600 years ago, steppe vegetation started to appear, followed quickly by animals such as bison, woolly mammoth, jackrabbits and voles. Importantly 11,500 years ago, the researchers identified a transition to a “parkland ecosystem” – a landscape densely populated by trees, as well as moose, elk and bald-headed eagles, which would have offered crucial resources for migrating humans.
Somewhere in between, the lakes in the area were populated by fish, including several identifiable species such as pike and perch. Finally, about 10,000 years ago, the area transitioned again, this time into boreal forest, characterized by spruce and pine.
The fact that Clovis was clearly present south of the corridor before 12,600 years ago means that they could not have travelled through it.
“Most likely, you would say that the evidence points to their having travelled down the Pacific Coast,” Willerslev added. “That now seems the most likely scenario.”
In some parts of the world, “fire adaptive communities” have learned to live compatibly with wildfire — in some cases for centuries or millennia.
Industrialized nations that view wildfire as the enemy have much to learn from people in some parts of the world who have learned to live compatibly with wildfire, says a team of fire research scientists.
The interdisciplinary team say there is much to be learned from these “fire-adaptive communities” and they are calling on policy makers to tap that knowledge, particularly in the wake of global warming.
Such a move is critical as climate change makes some landscapes where fire isn’t the norm even more prone to fire, say the scientists in a new report published in a special issue of the Philosophical Transactions of the Royal Society B.
“We tend to treat modern fire problems as unique, and new to our planet,” said fire anthropologist Christopher Roos, Southern Methodist University, Dallas, lead author of the report. “As a result, we have missed the opportunity to recognize the successful properties of communities that have a high capacity to adapt to living in flammable landscapes — in some cases for centuries or millennia.“
One such society is the ethnically Basque communities in the French Western Pyrenees, who practice fire management to maintain seasonally flammable grassland, shrub and woodland patches for forage and grazing animals. But the practice is slowly being lost as young people leave farming.
Additionally, Aboriginal people in the grasslands of Western Australia use fire as part of their traditional hunting practices. Children begin burning at a very young age, and the everyday practice is passed down. These fires improve hunting successes but also reduce the impact of drought on the size and ecological severity of lightning fires.
Social institutions support individual benefits, preserve common good
Fire-adaptive communities have social institutions in place that support individual benefits from fire-maintained landscapes while preserving the common good, said Roos, whose fire research includes long-term archaeological and ecological partnerships with the Pueblo of Jemez in New Mexico.
“These institutions have been shaped by long-histories with wildfire, appropriate fire-use, and the development of social mechanisms to adjudicate conflicts of interest,” said Roos, an associate professor in the SMU Department of Anthropology. “There is a wealth of tried and tested information that should be considered in designing local fire management.”
The authors note that globally, a large number of people use fire as a tool to sustain livelihoods in ways that have been handed down across many generations. These include indigenous Australians and North Americans, South Asian forest dwellers, European farmers, and also hunters, farmers and herders in tropical savannahs.
Global Warming will likely bring new fire problems, more flammable landscapes Global Warming will likely bring new fire problems, such as making some landscapes more flammable, Roos said. More effort will be required to balance conflicting fire management practices between adjacent cultures. Currently most fire-related research tends to be undertaken by physical or biological scientists from Europe, the United States and Australia. Often the research treats fire challenges as exclusively contemporary phenomena for which history is either absent or irrelevant.
“We need national policy that recognizes these dynamic challenges and that will support local solutions and traditional fire knowledge, while providing ways to disseminate scientific information about fire,” Roos said.
The authors point out that one of the greatest policy challenges of fire on a warming planet are the international consequences of smoke plumes and potential positive feedbacks on climate through carbon emissions. Most infamously, wildfire smoke plumes have had extraordinary health impacts during Southeast Asian “haze” events, which result in increased hospitalization and mortality in the region.
Not all fire is a disaster; we must learn to live with and manage fire Carbon emissions from wildfires can be as much as 40 percent of fossil fuel emissions in any given year over the last decade. Although only deforestation fires and land conversion are a net carbon source to the atmosphere, the contribution of wildfires to global carbon emissions is non-trivial and should be a formal component of international climate dialogs.
“It is important to emphasize that not all fire is a disaster and we must learn how to both live with as well as manage fire,” said co-author Andrew Scott, earth sciences professor at Royal Holloway University of London.
The report, “Living on a flammable planet: interdisciplinary, cross-scalar and varied cultural lessons, prospects and challenges,” was published May 23, 2016 by The Royal Society, the U.K.’s independent scientific academy.
Authors call for holistic study of fire on Earth The authors are from the United States, Great Britain, Canada, Australia, South Africa and Spain. The synthesis emerged from four days of international meetings sponsored by the Royal Society – the first of its kind for fire sciences.
The authors advocate for greater collaboration among researchers studying all aspects of fire.
Pyrogeography — the holistic study of fire on Earth , “may be one way to provide unity to the varied fire research programs across the globe,” the authors write.
“Fire researchers across disciplines from engineering, the natural sciences, social sciences and the humanities need to develop a common language to create a holistic wildfire science,” said Roos. “The magnitude of the wildfire challenges we face on a warming planet will demand greater collaboration and integration across disciplines, but our job won’t be done unless we are also able to translate our research for policymakers, land managers, and the general public.”

New evidence shows severe and rapid collapse of Pueblo populations occurred in the 17th century and triggered a cascade of ecological effects that ultimately had consequences for global climates

New interdisciplinary research in the Southwest United States has resolved long-standing debates on the timing and magnitude of American Indian population collapse in the region.
The severe and rapid collapse of Native American populations in what is now the modern state of New Mexico didn’t happen upon first contact with Spanish conquistadors in the 1500s, as some scholars thought. Nor was it as gradual as others had contended.
Rather than being triggered by first contact in the 1500s, rapid population loss likely began after Catholic Franciscan missions were built in the midst of native pueblos, resulting in sustained daily interaction with Europeans. The indirect effects of this demographic impact rippled through the surrounding forests and, perhaps, into our atmosphere.
Those are the conclusions of a new study by a team of scientists looking for the first time at high resolution reconstructions of human population size, tree growth and fire history from the Jemez Mountains of New Mexico.
“Scholars increasingly recognize the magnitude of human impacts on planet Earth, some are even ready to define a new geological epoch called the Anthropocene,” said anthropologist and fire expert Christopher I. Roos, an associate professor at Southern Methodist University, Dallas, and a co-author on the research.
“But it is an open question as to when that epoch began,” said Roos. “One argument suggests that indigenous population collapse in the Americas resulted in a reduction of carbon dioxide in the atmosphere because of forest regrowth in the early colonial period. Until now the evidence has been fairly ambiguous. Our results indicate that high-resolution chronologies of human populations, forests and fires are needed to evaluate these claims.”

A contentious issue in American Indian history, scientists and historians for decades have debated how many Native Americans died and when it occurred. With awareness of global warming and interdisciplinary interest in the possible antiquity of the Anthropocene, resolution of that debate may now be relevant for contemporary human-caused environmental problems, Roos said.
Findings of the new study were published Jan. 25, 2016 in the Proceedings of the National Academy of Sciences, “Native American Depopulation, Reforestation, and Fire Regimes in the Southwest U.S., 1492-1900 C.E.”

The researchers offer the first absolute population estimate of the archaeology of the Jemez Province – an area west Santa Fe and Los Alamos National Lab in northern New Mexico. Using airborne remote sensing LiDAR technology to establish the size and shape of rubble mounds from collapsed architecture of ancestral villages, the researchers were able to quantify population sizes in the 16th century that were independent of historical documents.
To identify the timing of of the population collapse and its impact on forest fires, the scientists also collected tree-ring data sets from locations adjacent to the Ancestral Jemez villages and throughout the forested mountain range. This sampling framework allowed them to refine the timing of depopulation and the timing of fire regime changes across the Jemez Province.
Their findings indicate that large-scale depopulation only occurred after missions were established in their midst by Franciscan priests in the 1620s. Daily sustained interaction resulted in epidemic diseases, violence and famine, the researchers said. From a population of roughly 6,500 in the 1620s fewer than 900 remained in the 1690s – a loss of more than 85 percent of the population in a few generations.
“The loss of life is staggering,” said anthropologist Matthew Liebmann, an associate professor at Harvard University and lead author on the PNAS article.
“Imagine that in a room with 10 people, only one person was left at the end of the day,” Liebmann said. “This had devastating effects on the social and economic lives of the survivors. Our research suggests that the effects were felt in the ecology of the forests too.”
Other scientists on the team include Josh Farella and Thomas Swetnam, University of Arizona; and Adam Stack and Sarah Martini, Harvard University.
The researchers studied a 100,000-acre area that includes the ancestral pueblo villages of the Jemez (HEY-mehz) people. Located in the Jemez Mountains of north central New Mexico, it’s a region in the Santa Fe National Forest of deep canyons, towering flat-topped mesas, as well as rivers, streams and creeks.
Today about 2,000 Jemez tribal members live at the Pueblo of Jemez.
The authors note in their article that, “Archaeological evidence from the Jemez Province supports the notion that the European colonization of the Americas unleashed forces that ultimately destroyed a staggering number of human lives,” however, they note, it fails to support the notion that sweeping pandemics uniformly depopulated North America.”
“To better understand the role of the indigenous population collapse on ecological and climate changes, we need this kind of high-resolution paired archaeological and paleoecological data,” said Roos. “Until then, a human-caused start to Little Ice Age cooling will remain uncertain. Our results suggest this scenario is plausible, but the nature of European and American Indian relationships, population collapse, and ecological consequences are probably much more complicated and variable than many people had previously understood them to be.”

It was a good year for SMU faculty and student research efforts. Here is a small sampling of public and published acknowledgements during 2015:
Hot topic merits open access
Taylor & Francis, publisher of the online journal Environmental Education Research, lifted its subscription-only requirement to meet demand for an article on how climate change is taught to middle-schoolers in California.
Co-author of the research was Diego Román, assistant professor in the Department of Teaching and Learning, Annette Caldwell Simmons School of Education and Human Development.
Román’s research revealed that California textbooks are teaching sixth graders that climate change is a controversial debate stemming from differing opinions, rather than a scientific conclusion based on rigorous scientific evidence.
Research makes the cover of Biochemistry
Drugs important in the battle against cancer were tested in a virtual lab by SMU biology professors to see how they would behave in the human cell.
A computer-generated composite image of the simulation made the Dec. 15 cover of the journal Biochemistry.
Scientific articles about discoveries from the simulation were also published in the peer review journals Biochemistry and in Pharmacology Research & Perspectives.
The researchers tested the drugs by simulating their interaction in a computer-generated model of one of the cell’s key molecular pumps — the protein P-glycoprotein, or P-gp. Outcomes of interest were then tested in the Wise-Vogel wet lab.
The ongoing research is the work of biochemists John Wise, associate professor, and Pia Vogel, professor and director of the SMU Center for Drug Discovery, Design and Delivery in Dedman College. Assisting them were a team of SMU graduate and undergraduate students.
The researchers developed the model to overcome the problem of relying on traditional static images for the structure of P-gp. The simulation makes it possible for researchers to dock nearly any drug in the protein and see how it behaves, then test those of interest in an actual lab.
To date, the researchers have run millions of compounds through the pump and have discovered some that are promising for development into pharmaceutical drugs to battle cancer.
Strong interest in research on sexual victimization
Teen girls were less likely to report being sexually victimized after learning to assertively resist unwanted sexual overtures and after practicing resistance in a realistic virtual environment, according to three professors from the SMU Department of Psychology.
The finding was reported in Behavior Therapy. The article was one of the psychology journal’s most heavily shared and mentioned articles across social media, blogs and news outlets during 2015, the publisher announced.
The study was the work of Dedman College faculty Lorelei Simpson Rowe, associate professor and Psychology Department graduate program co-director; Ernest Jouriles, professor; and Renee McDonald, SMU associate dean for research and academic affairs.
Consumers assume bigger price equals better quality
Even when competing firms can credibly disclose the positive attributes of their products to buyers, they may not do so.
Instead, they find it more lucrative to “signal” quality through the prices they charge, typically working on the assumption that shoppers think a high price indicates high quality. The resulting high prices hurt buyers, and may create a case for mandatory disclosure of quality through public policy.
That was a finding of the research of Dedman College’s Santanu Roy, professor, Department of Economics. Roy’s article about the research was published in February in one of the blue-ribbon journals, and the oldest, in the field, The Economic Journal.
Published by the U.K.’s Royal Economic Society, The Economic Journal is one of the founding journals of modern economics. The journal issued a media briefing about the paper, “Competition, Disclosure and Signaling,” typically reserved for academic papers of broad public interest.
Chemistry research group edits special issue
Chemistry professors Dieter Cremer and Elfi Kraka, who lead SMU’s Computational and Theoretical Chemistry Group, were guest editors of a special issue of the prestigious Journal of Physical Chemistry. The issue published in March.
The Computational and Theoretical research group, called CATCO for short, is a union of computational and theoretical chemistry scientists at SMU. Their focus is research in computational chemistry, educating and training graduate and undergraduate students, disseminating and explaining results of their research to the broader public, and programming computers for the calculation of molecules and molecular aggregates.
The special issue of Physical Chemistry included 40 contributions from participants of a four-day conference in Dallas in March 2014 that was hosted by CATCO. The 25th Austin Symposium drew 108 participants from 22 different countries who, combined, presented eight plenary talks, 60 lectures and about 40 posters.
CATCO presented its research with contributions from Cremer and Kraka, as well as Marek Freindorf, research assistant professor; Wenli Zou, visiting professor; Robert Kalescky, post-doctoral fellow; and graduate students Alan Humason, Thomas Sexton, Dani Setlawan and Vytor Oliveira.
There have been more than 75 graduate students and research associates working in the CATCO group, which originally was formed at the University of Cologne, Germany, before moving to SMU in 2009.
Vertebrate paleontology recognized with proclamation
Dallas Mayor Mike Rawlings proclaimed Oct. 11-17, 2015 Vertebrate Paleontology week in Dallas on behalf of the Dallas City Council.
The proclamation honored the 75th Annual Meeting of the Society of Vertebrate Paleontology, which was jointly hosted by SMU’s Roy M. Huffington Department of Earth Sciences in Dedman College and the Perot Museum of Science and Nature. The conference drew to Dallas some 1,200 scientists from around the world.
Making research presentations or presenting research posters were: faculty members Bonnie Jacobs, Louis Jacobs, Michael Polcyn, Neil Tabor and Dale Winkler; adjunct research assistant professor Alisa Winkler; research staff member Kurt Ferguson; post-doctoral researchers T. Scott Myers and Lauren Michael; and graduate students Matthew Clemens, John Graf, Gary Johnson and Kate Andrzejewski.
The host committee co-chairs were Anthony Fiorillo, adjunct research professor; and Louis Jacobs, professor. Committee members included Polcyn; Christopher Strganac, graduate student; Diana Vineyard, research associate; and research professor Dale Winkler.
KERA radio reporter Kat Chow filed a report from the conference, explaining to listeners the science of vertebrate paleontology, which exposes the past, present and future of life on earth by studying fossils of animals that had backbones.
SMU earthquake scientists rock scientific journal

Findings by the SMU earthquake team reverberated across the nation with publication of their scientific article in the prestigious British interdisciplinary journal Nature, ranked as one of the world’s most cited scientific journals.
The article reported that the SMU-led seismology team found that high volumes of wastewater injection combined with saltwater extraction from natural gas wells is the most likely cause of unusually frequent earthquakes occurring in the Dallas-Fort Worth area near the small community of Azle.
The research was the work of Dedman College faculty Matthew Hornbach, associate professor of geophysics; Heather DeShon, associate professor of geophysics; Brian Stump, SMU Albritton Chair in Earth Sciences; Chris Hayward, research staff and director geophysics research program; and Beatrice Magnani, associate professor of geophysics.
The article, “Causal factors for seismicity near Azle, Texas,” published online in late April. Already the article has been downloaded nearly 6,000 times, and heavily shared on both social and conventional media. The article has achieved a ranking of 270, which puts it in the 99th percentile of 144,972 tracked articles of a similar age in all journals, and 98th percentile of 626 tracked articles of a similar age in Nature.
“It has a very high impact factor for an article of its age,” said Robert Gregory, professor and chair, SMU Earth Sciences Department.
The scientific article also was entered into the record for public hearings both at the Texas Railroad Commission and the Texas House Subcommittee on Seismic Activity.
Researchers settle long-debated heritage question of “The Ancient One”

The research of Dedman College anthropologist and Henderson-Morrison Professor of Prehistory David Meltzer played a role in settling the long-debated and highly controversial heritage of “Kennewick Man.”
Also known as “The Ancient One,” the 8,400-year-old male skeleton discovered in Washington state has been the subject of debate for nearly two decades. Argument over his ancestry has gained him notoriety in high-profile newspaper and magazine articles, as well as making him the subject of intense scholarly study.
Officially the jurisdiction of the U.S. Army Corps of Engineers, Kennewick Man was discovered in 1996 and radiocarbon dated to 8500 years ago.
Because of his cranial shape and size he was declared not Native American but instead ‘Caucasoid,’ implying a very different population had once been in the Americas, one that was unrelated to contemporary Native Americans.
But Native Americans long have claimed Kennewick Man as theirs and had asked for repatriation of his remains for burial according to their customs.
Meltzer, collaborating with his geneticist colleague Eske Willerslev and his team at the Centre for GeoGenetics at the University of Copenhagen, in June reported the results of their analysis of the DNA of Kennewick in the prestigious British journal Nature in the scientific paper “The ancestry and affiliations of Kennewick Man.”
The results were announced at a news conference, settling the question based on first-ever DNA evidence: Kennewick Man is Native American.
The announcement garnered national and international media attention, and propelled a new push to return the skeleton to a coalition of Columbia Basin tribes. Sen. Patty Murray (D-WA) introduced the Bring the Ancient One Home Act of 2015 and Washington Gov. Jay Inslee has offered state assistance for returning the remains to Native Tribes.
Science named the Kennewick work one of its nine runners-up in the highly esteemed magazine’s annual “Breakthrough of the Year” competition.
The research article has been viewed more than 60,000 times. It has achieved a ranking of 665, which puts it in the 99th percentile of 169,466 tracked articles of a similar age in all journals, and in the 94th percentile of 958 tracked articles of a similar age in Nature.
In “Kennewick Man: coming to closure,” an article in the December issue of Antiquity, a journal of Cambridge University Press, Meltzer noted that the DNA merely confirmed what the tribes had known all along: “We are him, he is us,” said one tribal spokesman. Meltzer concludes: “We presented the DNA evidence. The tribal members gave it meaning.”
Prehistoric vacuum cleaner captures singular award

Science writer Laura Geggel with Live Science named a new species of extinct marine mammal identified by two SMU paleontologists among “The 10 Strangest Animal Discoveries of 2015.”
The new species, dubbed a prehistoric hoover by London’s Daily Mail online news site, was identified by SMU paleontologist Louis L. Jacobs, a professor in the Roy M. Huffington Department of Earth Sciences, Dedman College of Humanities and Sciences, and paleontologist and SMU adjunct research professor Anthony Fiorillo, vice president of research and collections and chief curator at the Perot Museum of Nature and Science.
Jacobs and Fiorillo co-authored a study about the identification of new fossils from the oddball creature Desmostylia, discovered in the same waters where the popular “Deadliest Catch” TV show is filmed. The hippo-like creature ate like a vacuum cleaner and is a new genus and species of the only order of marine mammals ever to go extinct — surviving a mere 23 million years.
Desmostylians, every single species combined, lived in an interval between 33 million and 10 million years ago. Their strange columnar teeth and odd style of eating don’t occur in any other animal, Jacobs said.
As noted by the CERN Courier — the news magazine of the CERN Laboratory in Geneva, which hosts the Large Hadron Collider, the world’s largest science experiment — more than 250 scientists from 30 countries presented more than 200 talks on a multitude of subjects relevant to experimental and theoretical research. SMU physicists presented at the conference.
The SMU organizing committee was led by Fred Olness, professor and chair of the SMU Department of Physics in Dedman College, who also gave opening and closing remarks at the conference. The committee consisted of other SMU faculty, including Jodi Cooley, associate professor; Simon Dalley, senior lecturer; Robert Kehoe, professor; Pavel Nadolsky, associate professor, who also presented progress on experiments at CERN’s Large Hadron Collider; Randy Scalise, senior lecturer; and Stephen Sekula, associate professor.
Sekula also organized a series of short talks for the public about physics and the big questions that face us as we try to understand our universe.
