- The claim that all mitochondrial DNA is transmitted via females has
- been known to be false since the 1970's. A small proportion is in fact
- transmitted by patrilineal descent. My source is a recent issue of
- Science et Vie (a French monthly which you might compare with
- Scientific American), in which the Eve hypothesis was discussed.
-
- Further, if all mitochondrial DNA was inherited matrilineally, the
- proponents of the Eve hypothesis would still be guilty, this time
- of circular reasoning and, again, of selective use of the data.
- The circular reasoning and selected use of the data are this:
-
- Let there be traits only transmissible via females.
- Let us consider those traits in restituting the phylogeny of
- the species.
- Since those traits are transmitted only by females, the
- nodes of the tree, and therefore its root, represent females.
- Therefore, all individuals are descended from the same female.
-
- Intellectual dishonesty and hocus pocus, nothing more.
