We are very much on the natural evolutionary course, Jojo. There is only one evolutionary course and we are definitely on it, yes siree!
That of course is not to say that we are not doomed

We most definitely are, sooner or later. If we mange to dodge all the sooner stuff, then theres the molten iron core of the Earth cooling, resulting in the disappearance of the magnetosphere, resulting in every organic form of life on earth being killed off with massive amounts of radiation from Sol (our sun), assuming of course that the Earths core cools before Sol starts to run out of fuel and the photosynthesis cycle stops (if youve ever been under the penumbra/umbra of a solar eclipse youll have some idea of what this would be like), and then just to top things off nicely, whats left of Earth will be 'atomised' when Sol explodes as a supernova..
The human race has no right to exist, the end
will come.
And I wouldnt worry about genetics in medicine; itll probably be a good thing. One can rarely say a good thing about chronic disease etc. I understand that 50% of human DNA is identical to the DNA of a banana (this could explain a lot

), so the DNA from a chicken is practically like DNA from ones own family
In the meantime, eat, drink, and be merry
Hope this helps.
Best regards,
Paul.
PS: There is much to be concerned about Jojo, but its comforting to know that one cant do a damned thing about it!
