Hypotheses
- Agriculturalist populations will have lower infant and child mortality rates than hunter-gatherer populations.Volk, Anthony A. - Infant and child death in the human environment of evolutionary adaptation, 2013 - 3 Variables
High infant and child mortality rates are suggested to be one of the most enduring and important features of ancestral human environments, referred to as the Environment of Evolutionary Adaptedness (EEA). These rates contrast with the very low rates of infant and child mortality among many industrialized nations since the 19th and 20th centuries. The authors compare data from recent hunter-gatherer and agricultural societies, historical records, and non-human primates in attempt to quantitatively describe infant and child mortality rates during the EEA.

The idea that archaic humans used wooden clubs as weapons is popular but not based on much archaeological evidence, due to the poor preservation of organic materials in the archaeological record. A new study analyzed 57 recent hunting-gathering societies and found that the majority used clubs for violence and/or hunting. The use of throwing sticks was less frequent. The study suggests that the use of clubs by early humans was highly probable, but that prehistoric weapons may have been quite sophisticated and carried strong symbolic meaning. The great variation in the forms and use of clubs and throwing sticks among recent hunter-gatherers suggests that similar variation may have existed in the past.

Previous studies have proposed a model of sexual selection that dictates that along with female and male choice, parental choice constitutes a significant sexual selection force in our species. This article aims at examining whether this model can also account for the mating patterns typical of agricultural and pastoral societies. The hypotheses are supported by the results presented.

This study tests possible explanations for sexual dimorphism in human post-reproductive life-spans. The author focuses on explanations involving male paternal investment and finds that men in agricultural societies are more likely to invest in their offspring than men in hunter-gatherer societies.

This article seeks to reevaluate the widespread assumption that hunter-gatherers lack the longevity that people in the modern, industrialized world enjoy. Through modeling life expectancy, mortality, and other demographic trends among extant hunter-gatherer, gatherer-horticulturalists, and horticulturalists societies they are able to challenge this belief. The authors conclude that longevity is a "novel feature of Homo sapiens" and that seven decades seems to be the natural lifespan of a human.
