First, we have sole-genetic progenitorship. In this case, we all descend from Adam and Eve, and their descendents never interbreed with others. This is a fairly important to some people, such as @Agauger.
Second, we have sole-genealogical progenitorship, where Adam and Eve are most likely genetic ghosts. This is how we usually think about Genealogical Adam models. We all descend from Adam, but we are not likely to have any of their DNA.
Now to the new category, I’m not sure what to name.
This is, in many ways, a subcategory of sole-genealogical progenitorship, however interbreeding is limited substantially. So we all have DNA from Adam and Eve, but maybe also from others. In these models there is interbreeding, but not as much as a recent Genealogical Adam. We might have some DNA from other lines, but it will always be small amounts, yet we are all fully human.
Let me propose a few possible “labels” for this category, and then let’s discuss the unique theological questions that arise here. For a label:
- Genetic Progenitorship (but not sole)
- Nearly Sole-Genetic Progenitorship
- Genetic Progenitorship with Rare Interbreeding
I lean to #2. What do you think?
Now, there do seem to be some theological questions that arise in this approach. I hesitate to call them “problems”, but they are questions.
- Especially alongside de novo creation, why did God make Adam capable of interbreeding with others?
- Is the interbreeding a good or bad event?
- What is the theological/biological status of the hybrids (e.g. 50/50 Sapiens and Neanderthal)? Are they fully human?
- Are people alive today with Neanderthal DNA fully human? If so, why are Neanderthal’s not fully human?
There probably are coherent answers to these questions, though I have not thought closely about this. The recent Genealogical Adam model’s we have put forward give answers to questions like this in a different way. By affirming monophylogeny, and inferring God wanted Adam’s offspring to interbreed with others, most these questions go away. I think they rise to higher prominence in these models
