Resources for defending the Church's teaching on monogenism?

Hello my friends,
If any of you would know some useful resources that I would be able to use, it would be very much appreciated.

Thank you very much.
God bless you.

Here is one:

Science, Theology, and Monogenesis by Kenneth W. Kemp

This post on a previous CAF thread might also be helpful, especially in that it provides a link to another resource defending the Catholic doctrine of monogenism:

The article cited in the post also refers to the Kemp article (see my previous post).

I thought that interbreeding between near relatives was a problem.

I wrote a research paper on this topic for my Theology masters. Here’s an exert that may help you:
A recent development in this field of genetics involves the tracing of the male Y-chromosome and the female mitochondrial DNA. Scientists can re-trace branches of ancestry of multiple cultures and races and determine when and where the branches “came together” to a common past parent. Earlier research had resulted in finding a common male “father” for the entire human race somewhere in the time-frame of 50,000 to 115,000 years ago and a common female “mother” in the time-frame of 150,000 to 240,000 years ago. Scientists struggled to theorize how the common “mother” and “father” could live tens of thousands of years apart. Interestingly, the geneticists gave their original male and female the names “Y Chromosome Adam” and “Mitochondrial Eve”. The most recent advancement in genome research was presented in August of 2013 in the professional journal “Science”. A world-wide sampling of DNA from 69 men resulted in the refining of the estimated life of “Y Chromosome Adam” to between 120,000 to 156,000 years ago. Consequently the best estimates of today’s geneticists point to a striking possibility that “Y Chromosome Adam” and “Mitochondrial Eve” were indeed contemporaries. Although these amazing findings receive scarce attention from secular culture and academia, they clearly refute the popular notion of polygenism and vindicate Pope Pius XII’s teaching in “Humani Generis” and indeed the ancient teaching of the Genesis text itself.

This is extremely helpful my friend, thank you. I believe this to be an important part of apologetics because if you can undermine Adam and Eve, you can undermine Christianity.

From Wayman’s article: “We’re not saying they’re exact contemporaries or they actually met or all men and women descended from the same couple,” says study coauthor Carlos Bustamante of Stanford University. Y Chromosome Adam and Mitochondrial Eve aren’t the first human man and woman either, but they are real people whose Y chromosome and mitochondrial DNA have been passed down with modifications to every living male and female.

Yes, these recent genetic discoveries don’t prove monogenism…however they certainly are consistent with what we would expect to find. Additionally I would say they dispel the popular notion that the distinguishing features of different races of humans (African, Asian, etc.) point to a polygenistic origin of man. We now know that all current races of mankind originate from a single man and a single woman. Yes, it is possible that there were other men and women alive at the time of Y Chromosome Adam and Mitochondrial Eve, and that their “branches” died out. However, one would expect to find that all of those contemporaries of Y Chromosome Adam and Mitochondrial Eve also could trace their ancestors to a single man and woman, and so on, and so on…until we get to our original parents. These most recent genetic discoveries are wholly consistent with monogenism.

Indeed, that kind of polygenism was a popular notion in the mid-20th century and earlier, perhaps in part due to sheer racism, in part due to ignorance.

But now, indeed, the science shows that race in the human species is not a very significant concept genetically. The scientific evidence is strong that we all spring from a common ancestral population.

Of course, the evidence is also strong that the population size was never as small as two, but that is dealt with in the articles I cited.

To be clear, the Church teaches that all of humanity can trace it’s ancestry back to two individuals.

That said, these two individuals might not be the only members of the species that were alive at the time. They are just the first two individuals endowed with rational souls, whose descendants all had rational souls. There may have been other near members of the species quite early on who were not endowed with such souls, who could have been bred with. Over time, rational souls were distributed throughout all of the remaining population down from these two individuals. Church teaching doesn’t preclude a scenario such as this.

Indeed. You have concisely and accurately summarized the scenario Kemp proposes.
Thank you.

Antoine Suarez published articles similar to Kemp’s.


“Transmission at generation”: Could original sin have happened at the time when Homo sapiens already had a large population size?


Can we give up the origin of humanity from a primal couple without giving up the teaching of original sin and atonement?
