Hundreds of microscopic fossils show that organisms emerging after an ancient glaciation evolved tough exteriors to weather the frozen climate.

Why We Don't See in Infrared
Topic: Origin & Evolution of Life

A new fossil recovered in China indicates that bird and crocodile family trees split earlier than previously thought.

New Evidence Challenges Oldest Signs of Life
Topic: Origin & Evolution of Life
05/21/11
Ancient rocks are shedding new light on the timeline for life's emergence on Earth. The rocks contain carbon-based minerals that may be much younger than the rocks they inhabit, indicating that the carbon was mixed with the rock later than the rock's actual formation.

A Prehistoric Microbial World in a Glass of Wine
Topic: Origin & Evolution of Life
