New genetic research finds shark, human proteins stunningly similar
Date:12/5/2013

ormed young, while some lay eggs. In some species, the embryos eat the remaining eggs or even other embryos while still developing in the uterus. Some can dive very deep, others cannot. Some stay local; others migrate across the entire ocean basins. White sharks dive deep, migrate very long distances and give live birth. We will use what we've learned in this species in a broader comparative study of genes involved in these diverse behaviors."

Because sharks are apex predators, their decreasing number threatens the stability of marine ecosystems, on which millions of people rely for food. This study also increased the number of genetic markers scientist can use to study the population biology of great white and related sharks, Stanhope said, by a thousandfold, from which they hope to further expand knowledge of these fascinating animals, many of which are in urgent need of conservation.
