Things that can’t survive don’t. But why would that fact drive nature to produce anything as simple as a kitten?
It is just not Darwin’s world any more.
Darwinian evolution, which most lay hearers assume to be “evolution” period, assumes that evolution is vertical.
In the history of life, some forms survive while — or even by — losing information.
To the extent that epigenetics casts doubt on simplistic Darwinian or other schemes of evolution, its main role may be that of “spoiler.”
