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.

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? Daniel Lieberman explores how running evolved and its role in human evolution.

All animals need to be physically active, but the human lineage clearly underwent selection to be considerably more physically active than our relatively inactive ape ancestors and cousins including chimpanzees and gorillas. Bipedal walking brought many benefits but also rendered hominins slow and awkward, hence vulnerable to predation. With the origins of hunting and gathering in the genus Homo, there was additional selection for endurance running which helped hominins become scavengers and hunters. Today we face a growing epidemic of physical inactivity that increases people’s vulnerability to a wide range of diseases.

The Southern California Coastal Ocean Observing System (SCCOOS) – part of the national U.S. Integrated Ocean Observing System (IOOS) – works to collect, integrate and deliver coastal and ocean observations in order to improve safety, enhance the economy, and protect the environment. SCCOOS serves a diverse stakeholder community of managers and planners, operational decision-makers, scientists, and the general public. Join SCCOOS Executive Director Clarissa Anderson as she describes how SCCOOS technology and observational programs provide information critical to decision-making related to climate change, coastal hazards, marine ecosystems, fisheries, water quality, and marine operations.

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 human metabolism and its role in our evolution and health. From an evolutionary perspective, life is a game of turning energy into offspring. The strategies that species use to acquire energy, in the form of food, and allocate energy to the essential tasks of growth, maintenance, movement, and reproduction, are incredibly diverse and reflect the ecological pressures and opportunities encountered. There is a deep evolutionary history of the human metabolic strategy and our divergence from other apes.

Human physical activities differ significantly from other species. Although hunter-gatherers sometimes climb and fight, they also walk and run long distances as well as dig, throw, carry and more. How, when and why did these capabilities evolve? What genetic, physiological and anatomical adaptations underlie them? And how did the evolution of human physical activity affect other key human characteristics such as the brains, diet, life-history strategies, gene-culture co-evolution and social cooperation? To address these and other related questions, this symposium will integrate research on genetics, biomechanics, physiology, neurobiology and behavior. Because more and more humans today are primarily sedentary, we will also explore implications of the evolution of human physical activity for contemporary health and disease.

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? David Raichlen explains the effects of physical activity on the brain and its role in evolution.

Recent work suggests exercise can have important beneficial effects on the aging brain, however the underlying mechanisms remain poorly understood. An evolutionary-neuroscience approach may help us better understand these mechanisms and can provide a foundation for developing novel interventions to improve brain aging.
