CARTA - Anthropogeny (Audio)

ABO Blood groups represent the first described human molecular polymorphism. The ABO gene encodes variants of a protein (a glycosyltransferase) that produces the short sugar chains on glycoproteins and glycolipids that define the A, B, or O antigens. These antigens are found on red blood cells, plasma glycoproteins, and other cell types in various tissues. Individual humans can have one of four blood types based on the two alleles inherited from both parents at the ABO locus: blood type A, B, AB, or O. UC San Diego professor Pascal Gagneux discusses how recent comparative genome studies have revealed that this polymorphic system is ancient and shared between humans and non-human primates, this despite the fact that none of the great ape species carries all four ABO blood types.

Humans are unusual in that we depend on shared foods, especially among families and friends and between potential mates. Food sharing occurs between healthy individuals and those that are infirm or elderly. We also differ from other great apes in our early ages at weaning, late ages at maturity, short birth intervals and survivorship decades past menopause. The emergence of these patterns was crucial to early human development. In light of observations among modern East African hunter-gatherers, University of Utah professor James O’Connell evaluates two alternatives. He discusses one hypothesis that focuses on males acquiring big game meat and marrow to provide for mates and offspring. The other hypothesis surrounds how certain kinds of savanna plant food set up the forager interdependence which propelled all aspects of life history change.

Discussion session about The Evolution of Human Physical Activity. Series: "CARTA - Center for Academic Research and Training in Anthropogeny" [Science] [Show ID: 37188]

Human physical activities differ significantly from other species. How, when and why did these capabilities evolve? What adaptations underlie them? And how did the evolution of human physical activity affect other key human characteristics that have advanced our species? Herman Pontzer explores the evolution of metabolism, Grazyna Jasienska discusses different effects of activity on women's reproductive health and Ellen Breen explores an evolutionary pathway for high endurance activity.

A growing body of evidence suggests that the evolutionary roots of much of the aggression, intolerance, and violence that plagues modern societies ultimately lies in the selection that shaped our mating system. Acknowledging and understanding the legacy of male interpersonal and group aggression can help guide policy directed at reducing violence in the future.

Human physical activities differ significantly from other species. How, when and why did these capabilities evolve? What adaptations underlie them? And how did the evolution of human physical activity affect other key human characteristics that have advanced our species? Jandy Hanna explores climbing in human evolution.

Most primates live and move in the trees, but humans have evolved to move bipedally on the ground. Primates’ arboreal life-style has long been thought to have allowed the evolution of human beings’ unusual form of movement. We know much about how horizontal movement on branches differs in primates relative to most other mammals. But only recently have we begun to learn about how climbing is accomplished by non-human primates, and how such movement may have permitted early human ancestors to move upright. Key findings regarding the biomechanics of climbing, and what these data may mean for understanding human movement and exercise, are discussed.

Human physical activities differ significantly from other species. How, when and why did these capabilities evolve? What adaptations underlie them? And how did the evolution of human physical activity affect other key human characteristics that have advanced our species? Grazyna Jasienska discusses different effects of activity on women's reproductive health. The effects of physical activity on female physiology and health are much more complex than for men. Just like in men, activity is beneficial for many aspects of health, but physically active women also face important physiological trade-offs. Physical activity influences levels of hormones that are crucial for female health – estrogens and progesterone. But how much and in what way these hormones are affected depends not only on the type and intensity of physical activity, but also on other factors, such as the quality of environment that women experienced during their own fetal development and childhood.
