6. Well ... you come from a *relative* of this. :)

It's very unlikely that any particular fossil organism is our direct ancestor, even if it's from the right phylum, class, order etc. The best we can say is that it's from a genetic population that's very close, *possibly* identical, to the one that led to us.

("If we evolved from monkeys, why are there still monkeys?" is the question to which this is the answer. We evolved from particular populations of primates, none of which exists today, but some of which split from the ancestors of surviving primate populations. The more recent the split, the more similar our genomes to those surviving primates. But none will have a genome identical to our direct ancestors -- those genomes evolved into us, or into other well-adapted, hence relatively long-surviving, primate populations.)
