Kennewick Man: genome sequence of 8,500-year-old skeleton solves scientific controversy

An 8,500-year-old male skeleton discovered in 1996 in Washington State sparked bitter disputes between Native Americans, American scientists, and within the American scientific community. Earlier studies suggested he was not ancestral to Native Americans, blocking repatriation. Now his genome sequence shows Kennewick Man is more closely related to modern Native Americans than to any other population worldwide. Continue reading

Science: What Caused a 1300-Year Deep Freeze?

SMU, comet, Meltzer, Clovis points, ScienceThe widely followed science news outlet Science covered the research of SMU archaeologist David J. Meltzer with the article What Caused a 1300-Year Deep Freeze?

The Science piece by Michael Balter highlights Meltzer’s new study showing a comet was not responsible for sudden climate change at the end of the Ice Age. Proponents of the comet-impact theory have pointed to sedimentary deposits that they say prove a comet hit the Earth, killing the Clovis culture and causing mass extinction of many animals. Continue reading

Nature: Prehistoric impact idea smacked down — dates of reported cosmic collision can’t explain North American extinctions

Meltzer comet, Nature magWidely followed science magazine Nature covered the research of SMU archaeologist David J. Meltzer with the article Prehistoric impact idea smacked down.

The Nature piece by Alexandra Witze focuses on Meltzer’s latest study to show that a comet was not responsible for sudden climate change at the end of the Ice Age 12,800 years ago. Proponents of the comet-impact theory have pointed to sedimentary deposits that they say prove that an object from outer space hit the Earth, killing the Clovis culture and causing the mass extinction of many animals.

Comet theory false; doesn’t explain cold snap at the end of the Ice Age, Clovis changes or mass animal extinction

Comet, Meltzer, SMU, Clovis, boundary layerControversy still rages over what sparked climate change at the end of the Ice Age 12,800 years ago, including a theory it was caused by a comet hitting the Earth.

As proof, proponents point to sediments with deposits they believe could only result from a cosmic impact. A new study disproves the theory, said lead-author and archaeologist David Meltzer, SMU. Continue reading

D Magazine: David Meltzer and other “Dallas Big Thinkers”

Meltzer%2CDavid%2C-DMag%2C-2011-250x213.jpgD Magazine journalist Dawn McMullan reported on the accomplishments of SMU archaeologist David J. Meltzer in the monthly magazine’s “Dallas’ Big Thinkers” article, which published Sept. 21.

A member of the National Academy of Sciences, Meltzer researches the origins, antiquity, and adaptations of the first Americans who colonized the North American continent at the end of the Ice Age. He focuses on how these hunter-gatherers met the challenges of moving across and adapting to the vast, ecologically diverse landscape of Late Glacial North America during a time of significant climate change.
