Throughout the evolution related posts you use arbitrary examples to show that any given species wide feature gave us a fitness advantage at some point. What about mutations that occurred in small populations and due to inbreeding or population bottlenecks fixated to what would become the dominant breeding population of the future?
What if a random mutation in an already somewhat breeding dominant male was spread to a population of 20, then some catastrophe affects all but these 20 creatures (chance fixation of arbitrary trait).
I guess my point is, I can think of at least 3 other ways you could get chance fixation of arbitrary allelles, and even more where you get majority carriership which can remain stable within a population without a fitness advantage being conferred by them.
This isn’t a point against your description of the mechanism of evolution but a point against picking a trait like anger and assuming it exists because it conferred a fitness advantage, although it may well.
