Evolution: Horses, speciation and environment (Evolution)

DAVID: Which came first, speciation or environmental changes requiring adaptation? Environmental changes!

DAVID’s comment: This finding seems logical to me. Move to a new area with better food and then adapt to the other environmental issues. Epigenetics play a role. However the varieties are all still horses and can interbreed. see below:

Your comment is right on the button. This is not speciation in the broad sense at all, but adaptation, and I must confess, I never knew there was any controversy! Since the whole point of adaptation is to cope with change, I find the reverse procedure totally illogical. Innovation is required for speciation in the broad sense, and as my own hypothesis relies on the same mechanism (the innovative as well as adaptive intelligence of cell communities), again I see it as only logical that the trigger will be environmental change offering opportunity (as opposed to threat). I think you disagree on this, though, as you have suggested that your God prepared the fish before it stepped out onto the land.
