If you include the effects developed life has on the environment that developing life exists in, every environment, even that which is affected by humans, would be part of the natural selection algorithm.
Say what?
One corn said to another...
Corn A : You taste sweet.
Corn B : Thank you but
you are Hardy and Strong.
Corn A: Shame we are so far apart we can't mix my Sweet gene with your Hardy gene for many many years.
Meanwhile Farmer reads Darwin's book... Hmmmm?
Farmer gets Corn B's pollen and drives miles and miles, through man caused storms, snow and heat, to Hand pollinate Corn A with B's Pollen .
Farmer patiently waits in the near flood conditions. Time passes...
Corn A: Look I am Sweet and Hardy now and maybe resistant to my changing environment since I survived.
Scientist quickly study the new Genetic structure of A:B=C... not bad
Others proclaim "its man made and FrankenCorn"
... danger!!!
Consumer demand rises, Famers make more Corn C, the world is fed with better hybrid GMO corn.
Moral to the story...
Dont GMO a bird with corn DNA. It may fly to pollenate Corn D.
