Ancient DNA Sheds New Light on the Biblical Philistines

A team of scientists sequenced genomes from people who lived in a port city on the Mediterranean coast of Israel between the 12th and 8th centuries B.C.

The team studied heritability of behavioral traits in three breeds: Maine Coon, Ragdoll and Turkish Van
