A paraphyletic group is a group of any size and systematic rank that originated from a single common ancestor, but does not – as opposed to a monophyletic group – contain all descendants from this ancestor. The ancestral species of this group is thus also the ancestor of one or more other groups
Humans are not descended from contemporary apes rather the apes that were around millions of years ago.
Also, if we attain the not-insignificant-anymore possibility of going extinct in the next couple hundred years (like the dinosaurs from famine complicated by drastic climate change, or from too many microplastics in the brain, or from nuclear escalation, which we haven't entirely ruled out) we will have only survived ~250,000 years compared to Homo-Erectus which survived over 2,000,000. But we will get the self-extermination achievement.
