evolution never stops. Perhaps humans as we are will disappear by self-destruction or by nature purging us like the virus we are (I love that MATRIX movie).
The key to evolution via humn intervention will rely on genetics, or more accurately, the ability to patch new genetic traits into existing organisms (Change your eye color NOW, increase your capacity to learn and retain information, increase the size of your... well you get it). The aging process will need to be reworked, that which causes our cells to stop reproducing will need to be altered. We will need to borrow the best genetic traits from other species, more powerful senses, regeneration (the KEY to curing nerve damage), upgraded immunity. Perhaps also the ability to render dentures obsolete by implanting synthetic tooth buds that allow regeneration of full adult teeth.
We will need to adapt filtration, better kidneys, better lungs. Build in a non-reaction to allergens, narcotics, etc.
Of course, the whole social system would need to be reworked to allow the humans who are now living longer and having a higher quality of life to not overpopulate the planet... selective fertilization perhaps?
The grander overall vision would be to have a collection of host organisms for your stream of consciousness (a-la Total Recall), one for each colonized planet, one that can deal natively with the environments (heat-cold-atmosphere-etc)... while we're at it, the ability to be amphibious would open up 7/10 of the earths surface to counter over-population.
1,000,000 years is a long time, the only thing I can be sure of is that I won't be around to see it😎
