Many different kinds of human species have walked the Earth
Homo sapiens is a pretty impressive species. We built the pyramids, landed on the moon and created the internet. All of our successes are the fortunate result of a tremendous evolutionary journey from ape to the hominins who would become modern humans.
Along the way, other human relatives emerged and disappeared. Most lived before we did; some of the more recent ones met up with our species before going extinct, for reasons that are still mysterious for scientists.
