I have only glanced at Pearl’s work, not read it carefully, so my understanding of causal networks is very limited. But I don’t understand on the basis of which data will you construct the causal network for anger and children (and it’s actually more complicated because there are important society-level effects). In what will you “see a relationship between A and C”? On the basis of what will you be calculating the likelihoods?

Ideally, you would have some record. I’m not an expert in evo psych, so I can’t confidently say what sort of evidence they actually rely on. I was hoping more to express how I would interpret a story as a formal hypothesis.
I get the impression that a major technique in evolutionary psychology is making use of the selection effect due to natural selection: if you think that A is heritable, and that different values of A have different levels of reproductive usefulness, then in steady state the distribution of A in the population gives you information about the historic relationship between A and reproductive usefulness, without even measuring relationship between A and C in this generation. So you can ask the question “what’s the chance of seeing the cluster of human anger that we have if there’s not a relationship between A and reproduction?” and get answers that are useful enough to focus most of your attention on the “anger is reproductively useful” hypothesis.
