Original sentence: According to this theory, the population of humans gradually evolved from other hominans, and the population size was never two (indeed if the population size had been just two, humans would almost certainly have become extinct).In modern times the theory of evolution has challenged the Christian belief in the historicity of Adam and Eve.Many denominations have rejected the historicity of Adam and Eve; others have retained it (at least officially), including The Church of Jesus Christ of Latter-day Saints and some conservative Christian denominations.Somewhat confusingly however, geneticists have identified individuals dubbed "Y-chromosomal Adam" and "Mitochondrial Eve".The idea of a single male and female human ancestor is contradictory to evolutionary theory
