Dating between modern humans and neanderthals - Neanderthal and Human Matings Get a Date

Radiocarbon dating of Neanderthal remains recovered from Vindija Cave Croatia initially revealed surprisingly recent results: This implied the remains could represent a late-surviving, refugial Neanderthal...

When scientists say that modern humans emerged in Africa about , years ago and began their worldwide spread about 60, years ago, how do they come up with those dates? Traditionally researchers built timelines of human prehistory based on fossils and artifacts, which can be directly dated with methods such as radiocarbon dating and Potassium-argon dating.

Howsoever, these methods require ancient remains to have certain elements or preservation conditions, and that is not always the case. Besides, relevant fossils or artifacts set up not been discovered for all milestones in human evolution.

Analyzing DNA from present-day and time-worn genomes provides a complementary style for dating evolutionary events. Owing to certain genetic changes occur at a steady rate per start, they provide an estimate of the time elapsed. Molecular clocks are becoming more sophisticated, thanks to improved DNA sequencing, analytical tools and a better intimacy of the biological processes behind genetic changes. By applying these methods to the ever-growing database of DNA from diverse populations both present-day and ancient Ban, geneticists are helping to figure a more refined timeline of human evolution.

Molecular clocks are based on two key biological processes that are the begetter of all heritable variation: These changes will be inherited not later than future generations if they become manifest in eggs, sperm or their cellular precursors the germline.
