The common ancestor to humans and sharks

"I'm your father"

It has been known for many years that man has a common ancestor with monkeys, and hence they are closest to our line of evolution.
If we go much further back in time, according to the magazine "Nature", we would also have a common ancestor with sharks, the Acanthodii .
This group is curious, since it is midway between bony fish and chondrichthyan group they belong to sharks and rays. With the latter have in common that their skeleton is made of cartilage, but have a long bone spurs at the end of their fins.
