Sharks have more proteins in common with humans than zebrafish!

Dr. Michael Stanhope from Cornell University has discovered that great white sharks actually share more proteins involved in metabolism and biochemistry in common with humans than zebrafish, a common fish model used in biomedical research. They made this discovery by sequencing the transcriptome of a heart isolated from a great white shark. I find it fascinating that sharks have more proteins in common with mammals than with bony fish, even though sharks and bony fish are not very closely related.

There aren't any. But, aquaria have many times tried to make it so, and it always goes bad for the shark. The basic problem is that great white sharks are pelagic, and it is very hard to keep pelagic creatures in a confined space, and the largest aquaria are very confined from the point of view of…

Alright all you evolutionary biologists, I expect to see you all replace your zebrafish tanks for shark tanks!

someone is gonna use this to try to discredit evolution again

anyway, just heart transcriptome? what if it was different in other organs? we need more sharks to sample
