Evolution Cannot Be Rolled Back

If our closest relative, the chimp, were to develop into a human being, it would require a series of unlikely evolutionary steps.

Six million years erased

To become human, the first step of chimps need to roll back about 6 million years of evolution to the common ancestor of the two species. Sometimes animals are born with traits from the species' evolutionary history.

Monkeys mutate into people

Then they must chance across the same mutations, which have been passed on to humans. This includes a series of highly unlikely gene copies, which have contributed to developing our brains.
