They found two really old skeletons in Europe that are older than other skeletons. They are skeletons of a "modern"-ish human. They know because the teeth of the skeletons have a specific thing that the teeth of humans have but not the teeth of other primates.
The older skeleton is 1 million years older than old skeletons found in Africa. So now the oldest skeletons that we know about come from Europe not Africa, raising the possibility that humans evolved in Europe.
