Researchers: Culture drives human evolution more than genetics
In a new study, University of Maine researchers found that culture helps humans adapt to their environment and overcome challenges better and faster than genetics.

Challenging a 75-year-old notion about how and when reptiles evolved during the past 300 million-plus years involves a lot of camerawork, loads of CT scanning, and, most of all, thousands of miles of travel. Just check the ...

There's a paradox within the theory of evolution: The life forms that exist today are here because they were able to change when past environments disappeared. Yet, organisms evolve to fit into specific environmental niches.
