While fewer species live in the ocean than on land, marine life represents much older evolutionary lineages that are fundamental to our understanding of life on Earth, Appeltans says.

The Liaoning specimen is especially significant because it means the fossil record now sits more comfortably with what genetic studies have been suggesting about the timing of the emergence of the different mammalian lineages.
"It's important to understand that these markers we're looking at only tell us about one or two lineages out of the hundreds of lineages we have of people who have contributed to our DNA, " he said.
Researchers also tracked the paper trail of their respective family lineages, which met at a shared ancestor named Diego de Montoya, who was born about 1596 in a part of Mexico then known as New Spain.
Stefansson left his spot as a professor at Harvard Medical School to found DeCode because he thought his native Iceland provided the perfect spot for discovering genes in families with lineages that have been tracked for generations.
