New research suggests we evolved from a primitive species of shark that lived 300 million years ago.
Acanthodes bronni is now believed to be the common ancestor of all jawed vertebrates including humans. The creatures were quite small at around one foot in length, had gills instead of teeth and would have fed on plankton. Fossils have been discovered in many parts of the world including Europe and North America.
"Unexpectedly, Acanthodes turns out to be the best view we have of conditions in the last common ancestor of bony fishes and sharks," said Professor Michael Coates. "It helps to answer the basic question of what is primitive about a shark. And, at last, we are getting a better handle on primitive conditions for jawed vertebrates as a whole."
"The primitive fish named Acanthodes bronni was the common ancestor of all jawed vertebrates on Earth – including mankind, according to new research."
