Researchers are resurrecting proteins from millions of years ago to understand evolution and lay the groundwork for bioengineering custom molecules.

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.

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

“Cheddar Man” had dark hair and blue eyes, a sequencing analysis suggests.

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. 

From DNA evidence, researchers estimate the split from other species took place between 260,000 and 350,000 years ago.

When engineered to use a four-billion-year-old version of the protein thioredoxin, the bacteria can stall bacteriophage replication, a new study shows.

Scientists are criticizing the claim that hominins were in North America more than 100,000 years earlier than the currently accepted estimation.
