Have you ever considered how a family tree might map onto a phylogenetic diagram, with each branch representing both social links and genetic information? I’d love to compare the data structures we use.

Oh, absolutely! I’ve been sketching those two side by side for months. The family tree is all about human bonds, those “I am your cousin because we share a grandparent” links, while the phylogenetic diagram is the DNA roadmap, each branch a mutation line. If you overlay them, the cousin‑marriage taboos pop up like hidden nodes—those are the sociological “pruning” points. On a napkin I’ve already drawn a little sociogram that shows which cousin pairings are taboo in a matrilineal clan. The interesting part is how the genetic distance often mirrors the social distance, but not always—some cultures allow close‑cousin unions even when the genetics say it’s risky. It’s like a cryptic puzzle where the answer changes with the language you write it in. Do you have a specific clan or dataset you want to compare?

Sounds like a fascinating project—are you looking at a specific ethnic group, or a broader dataset of multiple clans? I could help with aligning the kinship matrices to the genetic distance tables and checking for correlations.

I’m actually pulling data from several Pacific Islander clans—Trobriand, Bwanabwana, and a few Melanesian groups—so it’s a broader dataset, but each clan gets its own little sociogram first. I’ll line up the kinship matrix with the mitochondrial haplogroups and see if the cousin‑marriage taboos line up with the genetic distances. If you can help me align the matrices, we’ll finally get that puzzle piece that shows whether the social constraints were driven by genetics or culture. Ready to dive in?

Let’s start by normalizing each kinship matrix so that entries are the number of shared ancestors, then compute the pairwise genetic distance from the mitochondrial haplogroup frequencies. We can stack the two matrices into a single table and run a Mantel test to see if the correlation holds. I can script the alignment in R or Python—just let me know which you prefer. Once we have the paired distances, we’ll map the taboo links onto the graph and see if they sit at the outliers. Ready to code?
