Biologists are closing in on a puzzle that seems to turn classic evolutionary logic inside out, yet may be so common that it ...

Current efforts to stifle scientific theories in school are reminiscent of the attacks on the teaching of the theory of evolution. iStock / Getty Images Plus Scientific theory has had a rough time in ...

A major evolutionary theory says most genetic changes don’t really matter, but new evidence suggests that’s not true. Researchers found that helpful mutations happen surprisingly often. The twist is ...

Scientific theory has had a rough time in America’s public schools. The approach is not limited to evolution. Legislatures across the country are proposing or passing laws that purport to encourage ...

This has been quite the wild year in human evolution stories. Our relatives, living and extinct, got a lot of attention—from ...

Reporters from across the United States flocked to eastern Tennessee in July 1925. In the small town of Dayton, biology teacher John Scopes went on trial for the crime of teaching human evolution.

Yet modern biology has revealed that cells are preternaturally sophisticated assemblages — literally automated, miniaturized factories. How could the evidence have been overwhelming but now orthodoxy ...

One hundred years ago, the small town of Dayton, Tenn., became the unlikely stage for one of the most sensational trials in American history. A local substitute teacher, John Scopes, was charged with ...

A random mutation in a gene can alter its function and bring about a new characteristic that can pass down for many generations, but this may not be the only way that organisms can inherit a trait.
