Chinese researchers recently uncovered molecular evidence supporting Lamarckism—a long-debated theory from the early 19th century that acquired characteristics can be inherited. The evidence was ...

In Part One of this series, we saw that culture doesn't suffer from the problem that Darwin's theory of natural selection successfully solved: the problem of how change accumulates in biological ...

For well over a century, Darwin’s theory of natural selection has served as biology’s grand unifying framework, explaining how species adapt and evolve through the differential replication of randomly ...
