It seems to me that this is an attempt to appeal to evolutionary psychology to explain a cultural phenomenon. Maybe I'm provincial in thinking that property rights are grounded in sociology rather than biology, but if they were grounded in biology I would expect to see fewer convergences when different ethnic groups participate in a mostly common culture but still select reproductive partners who share their background. I would also find it trivially likely that within only a generation or two, the distribution of viewpoints regarding property rights would shift dramatically, unless there was significant selection pressure.
However, if property rights are memetic and cultural, I would expect both convergences due to social interaction without gene mixing, and large shifts in the course of a single generation, or even in one person during their adult life.
A basic conception of property rights is probably genetic whereas specific property laws are cultural. This is similar to the way our capacity for language as well as certain language universals are genetic while languages themselves are cultural.

This post is part of the Rerunning the Sequences series, where we'll be going through Eliezer Yudkowsky's old posts in order so that people who are interested can (re-)read and discuss them. The previous post was Protected From Myself, and you can use the sequence_reruns tag or rss feed to follow the rest of the series.
Sequence reruns are a community-driven effort. You can participate by re-reading the sequence post, discussing it here, posting the next day's sequence reruns post, or summarizing forthcoming articles on the wiki.
