Were we "human" 200.000 years ago the way we are now?

Was the required brain and vocal hardware present?

Of course they were. A human from 200,000 years ago would be almost genetically identical to one from today. That's what makes us homo sapiens. 200,000 years is absolutely nothing on an evolutionary timescale with generations as long as ours and reproduction rates as low as ours.

Yes. Some important parts of the software, like complex tools, art, or the use of symbols only appeared between 100.000 and 50.000 years ago, however.
