What do humans have in common with sharks

It might be hard to believe, but humans are actually related to sharks.The elephant shark’s genome, for example, is so similar to humans’ that we have more in common with it than other fish that previously ranked closer to us in the evolutionary tree. Sharks get tired after a long "workout" just like humans. For many species, this impacts their ability to breathe properly (sharks need to swim in order to breathe). Just like humans get training for a new job, sharks can be trained to do things just as well. Also, shark eyes and our eyes basically the same... Even if you’ve never seen a shark, you might have already looked into the eyes of one. Shark corneas have been successfully used for human corneal transplants, meaning somewhere out there, someone has a pair of shark eyes ;) (maybe because we’re related?).
