The analysis adds new details to the picture of migration and mixing in a diverse country.

Microscopic analysis of charred, shapeless lumps from archaeological sites revealed ancient cereal grains that may have undergone malting to make beer.

Genetics and archaeology yield clues as to when humans first arrived on the continent and how these early settlers lived.

A massive study finds that regional differences in how slaves were treated throughout the Americas are reflected in the DNA of present-day Americans of African descent.

If confirmed, the result means people migrated to North America much earlier than thought, but some experts remain unconvinced.

An isotopic analysis of eggshell beads dating back more than 30,000 years indicates that they helped build networks that stretched for hundreds of kilometers.

A new analysis of more than 2,500 human genomes indicates that modern Eurasians who acquired Neanderthal DNA during past interbreeding migrated back to Africa and spread those sequences.

Genomic information from four children who lived thousands of years ago in what is now Cameroon could shed light on the spread of the Bantu languages and on the history of present-day African populations.

For the past 10 years, life science has moved us closer to a complete understanding of what makes us human—our similarities, our differences, and our shared history.
