Being in a common ancestor is certainly compatible with evolution but it's not necessary because it could have evolved independently in each branch.

if it were only 2 primates that's a plausible explanation, but when it's pretty much every simean using tools, and all the old world apes making tools, it's pretty hard to argue for convergent evolution rather than a trait that exists ancestrally.
