You probably wanted to try Matthew 24:39. That's harder to overcome for evolutionists. That one is easy enough for an old-earch Creationist or theistic evolutionist to answer...
Humans have always been male and female, haven't they?
Besides, even from a literal reading of Genesis, God did make asexual organisms before man. Adam & Eve were the last to be made...
But mark 10:6 is harder for so-called Christians to answer, and that is whom I was addressing.
Jesus was talking about human beings, not asexual plants.
