(Phys.org) —We humans have been around for about 2.5 million years, but the beating of our hearts is controlled by something much older than Homo sapiens—an ancient molecular pathway that, according to Huck Institutes faculty researcher Tim Jegla, may be on the order of 700 million to a billion years old.
