Primates have evolved over 65 million years, from early ancestors to over 300 species today—including us. This is the incredible story of our ancient origins.

This timeline is based on studies from paleontology, developmental biology, morphology and from anatomical and genetic data. The study of human evolution is a major component of anthropology.

Evidence of early innovation pushes back timeline of human evolution "These behavioral innovations may very well represent a response to rapid changes in the environment," researcher Tyler Faith said.

The use of ancient DNA, including samples of human remains around 45,000 years old, has shed light on a previously unknown aspect of human evolution.

Beyond helping to reshape the known timeline of human evolution, the discovery also reinforces the notion that there was a much more extensive overlap between Homo sapiens and Neanderthals than ...
