In William Calvin's The Ascent of Mind, Chapter 8 he discusses why he thinks that the Acheulian hand-ax (the oldest of the fancy stone tools of Homo erectus) was really a "killer frisbee." He argues that natural selection for throwing accuracy, which requires brain machinery, is the evolutionary scenario for bootstrapping higher intellectual functions. There are many more articles about evolution and human development throughout William's extensive site, though much of it these days is on climate change.

The Sugar Addict's Total Recovery Program by Kathleen DesMaisons. While this isn't really a paleo book, it does point out issues with the foods we aren't eating. The books claims the excessive processed sugar consumed is responsible for "mood swings, depression, fatigue, fuzzy thinking, PMS, impulsivity ... [and] unpredictable temper." She says her research shows indulging in sugar highs should be treated much more seriously, akin to heroin or alcohol dependency, because sugar causes spikes in the neurotransmitters serotonin and beta-dopamine just like those drugs.

The Hiwi are not particularly healthy. Compared to the Ache, a hunter–gatherer tribe in Paraguay, the Hiwi are shorter, thinner, more lethargic and less well nourished. Hiwi men and women of all ages constantly complain of hunger. Many Hiwi are heavily infected with parasitic hookworms, which burrow into the small intestine and feed on blood. And only 50 percent of Hiwi children survive beyond the age of 15.
Grass-fed beef is often highlighted on the diet, which is promoted to contain more omega-3 fats than conventional beef (due to being fed grass instead of grain). It does contain small amounts of alpha-linolenic acid (ALA), a precursor to EPA and DHA. However, only a small proportion of ALA can be converted in the body to long-chain omega-3 fatty acids (EPA and DHA). The amount of omega-3 is also highly variable depending on the exact feeding regimen and differences in fat metabolism among cattle breeds.  In general, the amount of omega-3 in grass-fed beef is much lower than that in oily marine fish.  Cooked salmon contains 1000-2000 mg of EPA/DHA per 3-ounce portion, whereas 3 ounces of grass-fed beef contains about 20-200 mg of ALA.
