There's a negative pregnant in your statement that makes me think you believe in very recent human evolution. Is there reason to think humans have undergone any biological evolution since the development of agriculture?
Aside from lactose tolerance (or more accurately, lactase persistence, as the "wild type" is "intolerance"), there are differences in enzyme quantities in saliva due to copy number variations between those populations which have a history of consuming carbohydrates and those which do not. There are also the various resistances to malaria. For multiple reasons, including history (e.g., malaria seems to have become endemic in the Mediterranean over the course of the Roman Empire), we know these are all new, anywhere from 6,000 to 500 years before the present. I can give other examples, but these are the most clear and distinct in the literature.
Today's post, Zut Allais! was originally published on 20 January 2008. A summary (taken from the LW wiki):
Discuss the post here (rather than in the comments to the original post).
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 The Allais Paradox, 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. Go here for more details, or to have meta discussions about the Rerunning the Sequences series.
