The primitive fish named Acanthodes bronni was the common ancestor of all jawed vertebrates on Earth - including us, according to new research. A re-analysis of a braincase dating back 290 million years shows it was an early member of the modern gnathostomes - meaning 'jaw-mouths' that include tens of thousands of living vertebrates ranging from fish to birds, reptiles, mammals and humans. Acanthodes, a Greek word for 'spiny', existed before the split between the earliest sharks and the first bony fishes - the lineage that would eventually include human beings.
