We are now going through a stage of self-evolution so its not really possible to compare our current evolutionary progress to that of thousands of years ago.

Of course we are evolving faster but that is because we no longer have to wait for natures evolutionary crawl.

The fact people live a lot longer than they did 200 years ago proves our evolution is in our own hands as of now. Nature is not driving evolution anymore, in fact nature is almost redundant for those purposes.

We have taken over ourselves.

For instance, with genetic engineering we may one day be able to engineer humans who can breath atmospheres with no oxygen but full of carbon dioxide. So would nature be responsible for those tpyes of genetically modified humans? No...we would be the ultimate drivers of our own evolution.
