Early-Earth cells modeled to show how first life forms might have packaged RNA
(Phys.org)—Researchers at Penn State University have developed a chemical model that mimics a possible step in the formation of cellular life on Earth four-billion years ago. Using large "macromolecules" called polymers, ...

Shouldering the burden of evolution
As early humans increasingly left forests and utilized tools, they took an evolutionary step away from apes. But what this last common ancestor with apes looked like has remained unclear. A new study led by researchers at ...

Change in developmental timing was crucial in the evolutionary shift from dinosaurs to birds: study
At first glance, it's hard to see how a common house sparrow and a Tyrannosaurus Rex might have anything in common. After all, one is a bird that weighs less than an ounce, and the other is a dinosaur that was the size of ...

By precisely gauging the age of juvenile fossils, researchers show how early human ancestors were unique
For nearly a century, the debate has raged among evolutionary biologists: When working to understand how our early human ancestors developed, should juvenile fossils be thought of as fundamentally human or apelike?

Gene variations for immune and metabolic conditions have persisted in humans for more than 700,000 years
Like a merchant of old, balancing the weights of two different commodities on a scale, nature can keep different genetic traits in balance as a species evolves over millions of years.

Small enzyme-mimicking polymers may have helped start life
Most effort in origins of life research is focused on understanding the prebiotic formation of biological building blocks. However, it is possible early biological evolution relied on different chemical structures and processes, ...

Prehistoric birds lacked in diversity
Birds come in astounding variety—from hummingbirds to emus—and behave in myriad ways: they soar the skies, swim the waters, and forage the forests. But this wasn't always the case, according to research by scientists ...
