Evolution: Horses, speciation and environment (Evolution)

dhw: Anyway, clearly the latest research proposes environmental change first and adaptation second, in contrast to your fish adaptation first, exploration of dry land second.

DAVID: Land and sea are always different, no environmental change at the shoreline. What is your fish point? The green grass on land attracted the fish?

The environment is always changing. We don’t know why fish first came onto the land, but whatever may have been their reason, you insisted that your God had already prepared them beforehand, whereas I suggested they began the process of adaptation once they had emerged from the water. We needn’t go through all the details again. My point is that environmental changes require adaptation and also offer opportunities for new forms of life. I do not believe organisms adapt or innovate BEFORE the environmental change and then go looking for ways to use their adaptations/innovations, and your article appears to confirm this view.
