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? Ellen Breen explores an evolutionary pathway for high endurance activity.

We know Homo sapiens started in Africa, but we're uncertain about how they spread. Limited fossils and data have hindered our understanding. I'll discuss popular theories about our origins and how recent genetic data from Khoe-San people in southern Africa sheds light on this. Our research suggests a complex history, with population structures dating back to about 120,000-135,000 years ago. Early populations had connections, or gene flow, for hundreds of thousands of years. These "weakly structured stem" models explain genetic diversity that was once thought to come from other hominin species. Unlike previous ideas of interbreeding with archaic humans, our models predict that fossils from these populations should be genetically and physically similar. This variability in theories stems from not considering different possibilities, highlighting the importance of exploring various models to gain more accurate insights into our deep history.

The Science & Technology Ethics Center (STEC) is proud to present a series of lectures and a panel discussion that explores the intersection of genomics, medical ethics, and patient rights. This thought-provoking session delves into the ethical considerations surrounding genetic testing, data privacy, and informed consent. It examines the challenges and opportunities presented by advancements in genomics and how they impact patient care. The panel will discuss the importance of advocating for patients' rights, ensuring equitable access to genetic information, and fostering a patient-centered approach in genomic medicine. Throughout this presentation, you will grasp a deeper understanding of the ethical complexities in genomics and the critical role of patient advocacy in shaping responsible and inclusive genomic practices.
