New DNA technology is shaking up the family trees of many animals.
The thesis was that primates, to which humans belong, were once thought to be close relatives of bats because of some similarities in our skeleton (Primates: cladistic diagnosis and relationships - ScienceDirect) and brains (Flying primate hypothesis - Wikipedia).
However, DNA data now places us in a group that includes rodents (rats and mice) and rabbits.
Astonishingly, bats turn out to be more closely related to cows, [horses] (https://www.newscientist.com/article/dn9402-bats-and-horses-get-strangely-chummy/) and even rhinoceroses than they are to us.
The original thinking used similarities with skeletons and brain. DNA says no that conceptual thinking of similarities is wrong.
We all say science is self correcting. The fact that DNA has challenged long term thinking in this one area should cause us to question other tenets of evolution. No?
