Combining archaeological evidence with ancient DNA and data on past climates shows us how long and winding the story of human evolution is, stretching back millions of years to when the first primates ...

Here’s what you’ll learn when you read this story: The molecular clock theory posits that genetic changes happen steadily and gradually, offering a reliable means for peering into the past and ...

Researchers suggest that evolution may speed up dramatically during certain periods, challenging a long-held theory and helping explain a puzzling 30-million-year gap between genetic estimates and the ...

A digital reconstruction of a million-year-old skull suggests humans may have diverged from our ancient ancestors 400,000 years earlier than thought and in Asia not Africa, a study said Friday. The ...

Aquaporin (Aqp) 10 water channels in humans allow the free passage of water, glycerol, urea, and boric acid across cells. However, Aqp10.2b in pufferfishes allows only the passage of water and ...

The story of primates is a tale of incredible variety and ancient roots, told through the lens of science, DNA, and time itself. These creatures, ranging from massive gorillas to tiny mouse lemurs, ...

A team from the University of Illinois has uncovered surprising evolutionary links between the genetic code and tiny protein fragments called dipeptides. By analyzing billions of dipeptide sequences ...

"I'm stunned." says Per Ahlberg of Uppsala University, who coordinated the study; "A single track-bearing slab, which one person can lift, calls into question everything we thought we knew about when ...
