The evolutionary pressure to pass on DNA can produce behavior that otherwise makes no sense in a struggle to survive. Rams bash heads in fights over females; peacocks grow elaborate tail feathers that ...

Berkeley -- An international team of researchers has documented a remarkable example of natural selection in a tropical butterfly species that fought back - genetically speaking - against a highly ...

The virus that causes COVID-19 has accomplished something that school boards and other policy makers often refuse to do. It has given us a vivid, real-time lesson in how biological evolution works, ...

Natural selection is the process by which some organisms in a population survive and reproduce, while others do not, based on their bodies and behaviour. It is one of the processes by which species ...

A team of researchers reconstructed long-extinct proteins of a UV protection system of cyanobacteria. The surprising result: the proteins were already compatible with each other when they first met.

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 ...

Diseases have the potential to shape human evolution, leaving an indelible mark on the genetic code of generations to come. And that’s exactly what happened in South America, finds a study published ...
