New research suggests that natural selection, famous for rewarding advantageous differences in organisms, can also preserve similarities. The researchers worked with a plant called wild radish and its ...

When evolution skeptics want to attack Darwin's theory, they often point to the human eye. How could something so complex, they argue, have developed through random mutations and natural selection, ...

A strange tiny species of crustacean has challenged the way we think about natural selection and evolution. This microscopic animal, known as a water flea or Daphnia pulex, generates genetic variation ...

In 1858, English naturalists Charles Darwin and Alfred Russel Wallace independently reached the same groundbreaking conclusion — populations of living organisms change over time through natural ...

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 ...
