'This is why human evolution fails. Especially as according to a recent story, a bird managed to 'Evolve Twice'. Are they kidding? This is what really happened. It's called panspermia! Humans must have already had the right codes at their disposal. Wooohoooo!YAY! 'The Pre-existing human code simply matched Earths' conditions. 1) Bacteria DNA created the first life which quickly facilitated more complex life ALREADY in DNA. This is not 'evolution.' This is PROGRAM. Life had to start small to build up biomass to allow larger creatures which were already in the code, not there by 'evolution. ' Biodiversity is a SURVIVAL MECHANISM for the perpetuation of DNA, NOT an ecosystem.'
