Three members of a gene family called NOTCH2NL may have been involved in the evolution of humans’ big cortex.

Analyses of more than 300 ancient human genomes show that Hepatitis B virus has infected humans for at least 4,500 years and has much older origins than modern viral genomes would suggest.

Humans living in higher latitudes tend to have a variant of a gene involved in sensing cold temperatures, but it comes with a cost.  

The adaptation gives better endurance to the Bajau people, known as sea nomads, by increasing spleen size and, in turn, boosting the number of oxygenated red blood cells when diving.  

An 88,000-year-old finger bone places human ancestors in Arabia earlier than previously believed.

Researchers find that modern human populations carry distinct sets of genes from the extinct hominin species.

The animal pictures and hand stencils were made in caves in Spain thousands of years before Homo sapiens arrived in Europe.

The find is estimated to be at least 177,000 years old.

The genome of an infant who lived in Alaska thousands of years ago represents a previously unknown group of humans called Ancient Beringians, who share a common lineage with other Native Americans. 

Andean highlander genomes possess cardiovascular-related variants, while populations from other regions evolved different solutions to manage the lack of oxygen.
