...or epigenetics. This is supposedly not Lamarckism, but somehow involves the environment in leading evolution down particular paths.

This would be a way to explain the amount of change that is surmised to have occurred over the four billion years of Earth's existence... even though most mathematical models would suggest that even four billion years is not enough time for random chance and natural selection.

Epigenetics is a reasonable to answer to what we are seeing. Thanks for reminding me of that.
