All the other primates out there that have evolved into their current species over the last million years that we evolved into ours?

We’re all evolving. I don’t know which primate species would be considered the “newest” currently but that’s also probably being revised all the time as we discover more. But I’m sure either we’re not the “latest” or it’s pretty close.

We’re not the latest in some chain of primate species, being the ultimate version. Thats not how evolution works.
