Comparing Ancient And Modern Proteins
Researchers could answer some outstanding uncertainties by comparing ancient and current proteins in their respective sequences. They’d be able to figure out where Homo antecessor fit into the mix — were they a sister species to the human race, or did they belong somewhere else? Knowing this would also put an end to the controversy that has raged for years since the discovery in Spain in 1994.
Humans And Chimps
Experts have known for a long time that humans and chimps descended from a common ancestor who split into two species around nine to seven million years ago. Aside from that, they’ve known painfully little about how humans and monkeys evolved into their contemporary selves, and how many earlier incarnations of people and primates lived and died along the way.
