Swamidass’ model has always been a mixture of science and faith. The science says that it is entirely possible that there are universal genealogical ancestors that existed in the not so distant pass relative to the MRCA’s for mitochondrial and y chromosomal DNA. However, none of the science demonstrates that the male and female MRUGA’s lived at the same time, in the same area, or even had children with each other. Swamidass’ has simply found an unknown in science, and inserted A&E. Needless to say, if A&E did not exist then we would see these same geneaological and genetic patterns.
I would classify Swadmiass’ model the same as I would classify the Resurrection. There is no scientific evidence demonstrating that a man named Jesus did not rise from the dead around 33 AD, but there is no evidence that such a thing did happen. A&E as MRUGA’s would seem to fit the same bill.
However, none of the science demonstrates that the male and female MRUGA’s lived at the same time, in the same area, or even had children with each other.
However I never place Adam with MRUGA. I place instead with a vanilla UGA. We expect they arise everywhere, are often in couples, and there is much higher certainty in estimates about them.
Think about it, if Adam was monogamous and a UGA then for a fact Eve was too. That is just by basic logic. Your objection here is not correct.
