TL;DR: A theory is proposed that unites and organizes observations and generates many theoretical and empirical predictions that can be tested in future research by comparative biologists, archeologists, paleontologists, biological anthropologists, demographers, geneticists, and cultural anthropologists.

TL;DR: This work uses this population of hunters and gatherers living in the neotropical rainforest of eastern Paraguay to make a signal contribution to human evolutionary ecology.

TL;DR: It is found that hunter-gatherers display a unique social structure where either sex may disperse or remain in their natal group, adult brothers and sisters often co-reside, and most individuals in residential groups are genetically unrelated, which suggests large social networks may help to explain why humans evolved capacities for social learning.

TL;DR: In sum, the origin and maintenance of different human ontogenies may require explanations invoking both environmental constraints and selective pressures.

TL;DR: Data suggest that humans living as hunter‐gatherers would have attained a world population of more than 70 million individuals and a total biomass greater than that of any other large vertebrate on the planet if agriculture had not been repeatedly invented as they spread.
