People struggle to name odors [1-4]. This has been attributed to a diminution of olfaction in trade-off to vision [5-10]. This presumption has been challenged recently by data from the hunter-gatherer Jahai who, unlike English speakers, find odors as easy to name as colors [4]. Is the superior olfactory performance among the Jahai because of their ecology (tropical rainforest), their language f...
Our previous analysis of phytolith content of coprolites showed that calcium oxalate phytoliths from desert food plants caused dental microwear among prehistoric Texas hunter-gatherers. We demonstrated that phytoliths from desert succulents were ubiquitous and abundant in hunter-gatherer coprolites. We found that calcium oxalate phytoliths were harder than human dental enamel. We concluded that...
Imagine an individual called “hunter” that expends a good deal of energy to capture a gazelle. As the hunter is consuming his small prey, a second individual called “recipient” approaches and begins feeding peacefully alongside the hunter. A few weeks later the roles reverse, such that the previous recipient has now captured a gazelle, and the previous hunter is taking advantage of the recipien...
BACKGROUND Nutrition scientists are showing growing interest in the diet patterns of preagricultural (hunter-gatherer) humans. Retrojected preagricultural diets are reportedly predominantly net base producing in contrast to the net acid-producing modern Western diets. OBJECTIVE We examined the dietary net acid load [net endogenous acid production (NEAP)] for 229 worldwide historically studied...
