(Phys.org)—One of the most puzzling things about evolution is that, even after 4 billion years, it hasn't stopped. Instead of culminating in a single best adapted species, today the Earth contains an estimated 8.7 million ...
Darwinian evolution is the process by which natural selection promotes genetic changes in traits that favor survival and reproduction of individuals. How fast evolution happens depends crucially on the abundance of its "fuel": ...

During the earliest evolution on earth, life probably resembled one big genetic jumble. At some time, presumably around 3.8 to 3.5 billion years before today, the very first biological species appeared – the ancestor of ...

A chemical system of synthetic replicators shows the first signs of Darwinian evolution: Two different replicators compete for a common building block, and which one wins depends on the environment. As the replicators can ...
