Standing behind the African Eve hypothesis - the globalist mainstream view that humans evolved in Africa, which then became the mother continent – is the idea that there is only maternal inheritance of mitochondrial DNA. This is DNA in the mitochondria, not the chromosomes. The received position is that mitochondrial in human sperm, in the tail, gets excluded, a view held even in leading genetics journals.
But, it is not correct, as shown in the paper by F. Ankel-Simons and J. M. Cummins, “Misconceptions about Mitochondrial and mammalian Fertilization: Implications for Theories of human Evolution,” Proceedings of the National Academy of the Sciences, vol. 93, 1996, pp. 13859-13863. They state: “The “missing mitochondria” story seems to have survive – and proliferated – unchallenged in a time of contention, between hypotheses of human origins, because it supports the “African Eve” model of recent radiation of Homo sapiens out of Africa.” (p. 13859)
