The original creation of the RNA/DNA system appears obviously to be the work of a single pair of hands (God's). Nonetheless when you get to some point in the near pre-history of this planet, the picture changes; the engineering and re-engineering of complex life forms appears to have become a cottage industry with more than one pair of hands involved. There is no reasonable way to picture a well-intentioned God creating biting flies, ticks, chiggers, or disease organisms or any of the myriad creatures of Pandora's box. Likewise there is no reasonable way to picture God needing to go through 100 species of horses or elephants to get to the one he wanted.
Maybe it is a Junior Class in a cosmic Georgia Tech.
