Is there an evolutionary connection between the Blood Types of humans, chimpanzees and gorillas?

Question

Gorillas are all Blood Type "B"

Chimps are mostly "A", with a little "O"

Humans are 46% "O"

39% "A"

11% "B"

4% "AB"

Answer 1

that sounds like an evolutionary connection to me.

Answer 2

We also share 48% of our DNA with a cabbage, so what does that prove.

Answer 3

Chimps and humans split off from a common ancestor only 5 million years ago.  Of 35,000 genes, we share 34,500.  Chimp blood lacks just 1 enzyme, otherwise indistinguishable from human blood

Answer 4

I studied Hematology in medical school, blood types etc. This has nothing to do with an "evolutionary connection" as you state. Even worms have blood but, we're not connected.

        What you should be looking at is the genetic make-up the chromosomes. We have 23 in our genetic make-up a chimpanzee has 24.

         We can no more be close to a connection then a chicken with say 13 chromosomes.

Answer 5

Of course there is, silly.

Still, where did Rhesus negative blood come from? By rights it should have selected itself out of the gene pool as soon as it appeared, as it reduces the females ability to reproduce. Was it the original human blood type, and Rh+ has slowly been replacing it? Was it Neanderthal in origin? It's incidence is mainly over their range. Is the spread of Rh+ the reason we've lost a lot of Mt DNA haplogroups? Because it will make it hard for women to pass on Mt DNA (miscarriages and Hemolytic Newborn disease) if their mate is Rh+. Even Haldane wondered that one.
