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.
In Defense of Food: An Eater's Manifesto by Michael Pollan gives a guided tour of 20th century food science, a history of "nutritionism" in America and a look at the marriage of government and the food industry. Then the book presents a commonsense shopping-and-eating guide, which like the paleo diet focuses on shopping the perimeter of the supermarket. He also now has a much shorter Food Rules: An Eater's Manual.
The "CrossFit Games", directed by Dave Castro, have been held every summer since 2007. Athletes at the Games compete in workouts they learn about only hours beforehand, sometimes including surprise elements that are not part of the typical CrossFit regimen. Past examples include a rough-water swim, a softball throw, and a pegboard climb. The Games are styled as a venue for determining the "Fittest on Earth," where competitors should be "ready for anything."
Trying to introduce dairy back into my diet hurt my stomach and would send me into a sneezing fit. In this way, the Whole30 worked as a type of elimination diet for me, without which I may have never realized that dairy isn't my friend. I'll still suffer the consequences if I cross paths with a cheese plate at a work event, but I've made the permanent switch to tofu cream cheese and coconut milk — alternatives I would've never touched before Whole30 that are actually delicious.

Healthy, delicious, and simple, the Paleo Diet is the diet we were designed to eat. If you want to lose weight—up to 75 pounds in six months—or if you want to attain optimal health, The Paleo Diet will work wonders. Dr. Loren Cordain demonstrates how, by eating your fill of satisfying and delicious lean meats and fish, fresh fruits, snacks, and non-starchy vegetables, you can lose weight and prevent and treat heart disease, cancer, osteoporosis, metabolic syndrome, and many other illnesses.
Excluding foods. The exclusion of entire categories of commonly eaten foods like whole grains and dairy requires frequent label reading in the supermarket and in restaurants. It may also increase the risk of deficiencies such as calcium, vitamin D, and B vitamins, if these nutrients are not consistently eaten from the allowed foods or a vitamin supplement. For example, there are some nondairy calcium-rich foods that are absorbed well by the body such as collard and turnip greens or canned bone-in sardines and salmon, but you would have to eat five or more servings of these greens and fish bones daily to meet recommended calcium needs. (Note that some greens like spinach that are touted to be calcium-rich also contain oxalates and phytates that bind to calcium so very little is actually absorbed.) One small, short-term intervention study of healthy participants showed a 53% decrease from baseline in calcium intake after following a Paleo diet for three weeks.  Furthermore, the exclusion of whole grains can result in reduced consumption of beneficial nutrients such as fiber and thus may increase one’s risk for diabetes and heart disease.
Glassman reigns over this rampantly growing horde like a tribal chieftain. He now owns 100 percent of CrossFit and answers to no board of directors. Cash tends to race through the company. Until recently, the Glassmans each drew a salary of $750,000 a year; the travel and entertainment budget is in the tens of millions of dollars, and Glassman also spends money on what he calls "brand statements," including a set of $15,000 single-speed Swiss bikes and a $350,000, 1,500-horsepower fully customized 2011 Camaro convertible. (Before our visit to El Borracho, I followed him to a meeting to see about another "brand statement": custom luggage for his senior team, emblazoned with Uncle Pukie.)
This 2003 CrossFit Journal article captures an early conception of a universal, multi-event test of fitness that laid the foundation for CrossFit competition, including what would become the CrossFit Open and the CrossFit Games. The design requirements for such a test "included but were not limited to the following: quantifiable results; consistency with the CrossFit fitness concept; raising our commitment to improving absolute strength, relative strength, and gymnastic foundations; balancing intrinsic abilities of smaller and larger athletes; emphasizing exercises critical to and foundational to advanced training; mixing training demands within each test and, of course, over the total competition; a design that would identify an athlete’s weaknesses and possibly stand as a workout plan for improving overall fitness; and, finally, we wanted to design a competition that would be 'hard as hell.'"
