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? Tatum Simonson explains adaptations to altitude and diving.

Humans have persisted for hundreds of generations under challenging environmental extremes. Adaptations to such environments have been essential for survival, enabling populations to trek successfully among high mountain tops or to dive deeply into vast seas. Unique genetic signatures, resulting from thousands of years of strong selective pressures in these environments, have been discovered within the DNA of present-day populations. These findings provide important clues into evolutionary processes in humans. Series: "CARTA - Center for Academic Research and Training in Anthropogeny" [Science] [Show ID: 36946]

Climate scientist Julie Kalansky discusses how drought in California and Nevada is a common occurrence, with the attendant water restrictions and threat of severe wildfires bringing the reality of climate change into sharp focus. Future climate projections for the region suggest a trend toward more extremes, including more severe and prolonged drought as well as exceptionally wet years. Learn about the science of drought and how the Scripps-based California Nevada Climate Applications (CNAP) program works to provide drought tracking and early warning in support of drought preparedness and resilience in the face of a changing climate.

To study aging, scientists are looking to outer space. Space travel causes changes to the body that are similar to aging. Dr. Sonja Schrepfer, UCSF Division of Adult Cardiothoracic Surgery, investigates space-related physiological changes, similar to those observed during aging, including defects in bone healing, loss of cardiovascular and neurological capacity, and altered immune function.
