A great white shark's heart is strikingly similar to humans, according to a genetic study. Will we replacing the zebrafish in the labs with great white sharks?

Cornell University's professor Michael Stanhope—the lead author of the paper published in the journal BMC Genomics—found the similarities. He explains:
We were very surprised to find, that for many categories of proteins, sharks share more similarities with humans than zebrafish. [...]

Sharks have many fascinating characteristics. Some give live birth to fully formed 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.
What this study will lead to next is unknown just yet, but it could be used to study the population biology of the great white and other related sharks and expand our knowledge on them.
