A Multidisciplinary Contextualized Analysis of Select Passages From Genesis:

2:22a Yahweh God made a woman from the rib which he had taken from the man

[This is a rough draft for a new chapter to be included in a new edition of a personal study of the book of Genesis, the first edition of which can be found here. NOTE: THIS IS VERY ROUGH AND INCLUDES SOME SUMMARY DISCUSSION NOTES GENERATED BY GROK. Those details will be integrated in the final draft, but the responses are included in this draft post for expediency.

The purpose of this exercise is to compare a close reading of the text to our current understanding of language, paleontology, and the physical sciences. Constructive discussion on the elements presented is always encouraged!]

The story of Eve being formed using a portion of Adam is a wholly unique story among all the major religions. This account from Genesis literally described the process of extracting a rib from Adam and utilizing it in the formation of his ideal companion.

As it stands, the best sources for genetic material, growth cells, and stem cells:

Bone Marrow: 

Advantage: It's the primary site for hematopoietic stem cells (HSCs), which are responsible for producing all types of blood cells. Bone marrow transplants are used in treatments for leukemia, anemia, and other blood disorders because of these HSCs.

Benefit Over Other Sources: Bone marrow has a high concentration of stem cells, not just for blood but also mesenchymal stem cells which can differentiate into bone, cartilage, muscle, and fat cells. This makes it particularly valuable for regenerative medicine.

Benefits of Using Bone Marrow:

High Stem Cell Yield: For therapies requiring stem cells, bone marrow provides a rich source, especially for hematopoietic conditions.

Established Procedures: Techniques for extracting and using bone marrow in medical treatments are well-established, particularly in hematology and oncology.

Regenerative Potential: Beyond blood cells, mesenchymal stem cells from bone marrow have a broad differentiation potential, useful in tissue repair and regeneration.

Genetic Consistency: Since bone marrow is central to the body's cellular regeneration, it provides a genetic material that's representative of the individual's baseline genetic makeup, important for autologous treatments where the patient's own cells are used.

From a biological and medical perspective, the choice of bone for genetic material and growth cells often leans towards those with:

Red Bone Marrow: This is where hematopoiesis occurs, the process of blood cell formation. Bones like the pelvis, sternum, ribs, vertebrae, and the ends of long bones (like the femur) are rich in red marrow, making them ideal for studies or extraction involving stem cells or genetic material related to blood and immune cells.

In short, bone marrow contains the best and most available sources of genetic material and growth cells in the human body. And considering the best sources of marrow are largely structural bones, a rib is probably the one of least consequence functionally and the simplest to extract medically without risk to the patient.

Although this clearly suggests a methodology for cloning a human being, of particular interest is how a reproductively capable woman would be produced from the genetic source of a man.

It was at the beginning of the 20th century that biologist Nettie Stevens and her contemporaries identified the X and Y chromosomes. Identified as the genetic determinators for the sex of most of earth’s creatures, including humans, the male of the species possesses one X and one Y chromosome. The female, on the other hand, possesses two X chromosomes. Interestingly, besides being sourced from different people, these two X’s are not inherently different in that those of one’s mother are distinguishable from those of one’s father.

If one were to isolate the X chromosomes from a male donor, recombine them into a new XX pair, and insert them into the nucleus of an egg or stem cell, the resulting cells will grow into a female. Although there are some fine complexities to executing an actionable process including significant ethical considerations, there is no theoretical limitation barring this conceptually straightforward distillation of male DNA into a functional female genome.

But to create a male from a female XX chromosome pair would involve a direct editing process for one of the X chromosomes to create the Y variant. Technically this would be vastly more complicated since it isn’t a simple matter of cut-n-paste like in the aforementioned case. The peculiarities that make the Y chromosome unique are not found anywhere within the X chromosome. Segments would need to be authored ad hoc.

This does suggest that Adam and Eve are the most closely related couple imaginable to which one would infer their offspring would suffer from a lack of genetic variation. The autosomal inbreeding coefficient would theoretically be the improbable value of 1.0. A similar case occurs later in Genesis with Lot and his daughters which is a 0.125 coefficient.

None of these scenarios are considered sustainable as the smaller the coefficient the lower the risk. However, such unseemly relationships are rare and frowned upon even in the Bible. Whether or not for this specific reason, Leviticus 18 forbids relationships closer than first cousins which is a 0.0625 coefficient. That is the minimum diversity threshold for legal marriages in many western countries and largely considered generically safe, although a lower coefficient (greater genetic diversity) is generally better. 

As this interpretation of Genesis maintains that all accounts are serial, chapter 2 takes place after the initial seven “yom”. It is after God’s period of rest that he continues to interact with His creation. The planned “garden” (גַּ֥ן) of Eden is where He decides to place a collection of plants and creatures, including the human Adam, to interact with directly. Interestingly, they are all formed directly from dust instead of gathered from the life elsewhere on earth.

And if that process is reminiscent of the detail provided in the creation of Eve, it could have been through quietly procuring preferred genetic and stem samples. By this way He would populate this planned “garden” (גַּ֥ן) with naive realizations of each creature. The process of Eve’s formation would have been parsimonious given how God had likely performed such a procedure many times before.

In no way is this to suggest a limitation to the capabilities of God. However, it does support the principle of “Creatio ex potentia” (creation from potential) as His preferred method which is more scientifically viable than creation from nothing. And it resembles the same rather pedestrian method of sample selection and intentional cultivation. Not only is this description of the creation of Eve unique in origin lore, but is more scientifically relatable in comparison to all other creation narratives of the like.
