A far simpler solution is that all living beings have souls and God alone decides which are in His image…Yes, genetic monogenism is excluded for certain. Three independent lines of genetic evidence show that the genetic bottleneck was never less than a few thousand people:

As Inocente once pointed out, genetic monogenism would also imply inbreeding and incest, with all the messy genetic consequences of this.
However, given the metaphysics of human nature, theological monogenism, a real Adam and Eve (though not a genetic Adam and Eve) is still possible.
Here is Edward Feser’s excellent take on this (inspired by others that he cites):

Here is a summary of that position:
Scientific evidence strongly indicates that the genetic bottleneck for Homo sapiens was never smaller than a few thousand individuals, making untenable the idea of genetic monogenism (a literal biological Adam and Eve from whom every human being exclusively descended, also in biological terms). Feser suggests that God gave a soul to two humanoid creatures out of this population, making them human. Here you would have theological monogenism just like the Church teaches. Yet these first humans, or their descendants, then – according to continuing natural biological attraction – mated with other humanoid creatures without spiritual souls, and their offspring also received souls from God (just like now offspring from two ensouled parents receives a soul from God). That would explain biological polygenism, conferred to humans from natural interbreeding with surrounding humanoid creatures, even though only two people had souls originally. Having a rational soul, allowing for a true intellect, then gave a selective advantage, and within a few centuries all merely humanoid creatures were out-selected in favor of ensouled humans (as discussed in the second of the three web links). The human race (in the metaphysical sense, with all individuals having souls) was born.
Previously I had defended the idea that the Catholic Church might still settle on theological polygenism, given certain remarks in the Church document Communion and Stewardship, but given above elegant solution I have given up on that idea, since it simply has become unnecessary. Again, both theological monogenism and biological polygenism are possible at the same time, given the metaphysics of human nature.
