Two striking differences between humans and our closest living relatives, chimpanzees and gorillas, are the size of our brains (larger by a factor of three or four) and our life span (longer by a factor of about two). Our thesis is that these two distinctive features of humans are products of coevolutionary selection. The large human brain is an investment with initial costs and later rewards, which coevolved with increased energy allocations to survival. Not only does this theory help explain…

Neural Capital and Life span Evolution among Primates and Humans

This paper presents a theory of brain and life span evolution and applies it to both the primate order, in general, and to the hominid line, in particular. To address the simultaneous effects of

The Evolution of Human Life Expectancy and Intelligence in Hunter-Gatherer Economies.

The brain here is considered as a direct form of bodily investment, but also crucially as facilitating further indirect investment by means of learning-by-doing, which would theoretically expected that life expectancy and brain size would increase simultaneously.

The Role of Neoteny in Human Evolution: From Genes to the Phenotype

Recent advances in this field are described, which imply a molecular link between the evolution of two seemingly independent human-specific features: cognitive abilities and longevity.

The evolutionary roles of nutrition selection and dietary quality in the human brain size and encephalization

It appears that major expansion of brain size in the human lineage is the product of synergistically interacting dietary/nutritional and social forces.

Coevolution of cultural intelligence, extended life history, sociality, and brain size in primates

It is suggested that both brain expansion and high reliance on culturally transmitted behavior coevolved with sociality and extended lifespan in primates, consistent with the hypothesis that the evolution of large brains, sociality, and long lifespans has promoted reliance on culture.

Chapter 13 Human Survival and Life History in Evolutionary Perspective

This chapter focuses on human survival and life history: theoretical approaches and key features of human adaptability across time and space and characterizes human subsistence and sociality as important aspects of evolved life history.

The Centrality of Ancestral Grandmothering in Human Evolution

Ancestral grandmothering has become a serious contender to explain not only the large fraction of post-fertile years women live and children’s prolonged maturation yet early weaning; it also promises to help account for the pair bonding that distinguishes humans from the authors' closest living evolutionary cousins, the great apes, the evolution of their big human brains, and their distinctive preoccupation with reputations, shared intentionality and persistent cultural learning that begins in infancy.

A theory of human life history evolution: Diet, intelligence, and longevity

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.

Evolutionary research suggests that there are few fundamental biological barriers to the extension of human lifespan, only practical barriers.

Brain weight and life-span in primate species.

These findings suggest that in haplorhine primates the genetic systems controlling brain growth are linked to the systems governing the life cycle so that species with longer cycles have larger brains.

Life Historical Consequences of Natural Selection

The tremendous variation in the life-history patterns of organisms is best explained as adaptive, and a model of life history processes has been developed on the basis of these considerations, leading to the following predictions.

It is concluded that brain weight appears to be a slightly better predictor of life span than body weight but not better than adrenal weight.
