SUMMARY:Tracking a Killer: The Origin and Evolution of Tuberculosis
DESCRIPTION:In 2014\, Tuberculosis (TB) surpassed HIV as the leading cause of death from infectious disease. Unlike HIV\, TB has long been a scourge of humans; however\, exactly how long has been debated. Also controversial has been the presence and relationship of pre-Columbian tuberculosis in the Americas to TB strains in the rest of the World. In this lecture Anne Stone examines the evolutionary history of Mycobacterium tuberculosis\, the bacteria that causes TB\, focusing on the distribution of TB strains in humans (past and present) in order to understand their relationships\, assess patterns of pathogen exchange through time\, and investigate how TB adapted to humans and other animals. Her lab group uses new methods of ancient DNA extraction as well as methods to target pathogen DNA to obtain genetic data from ancient samples with characteristic TB bone lesions. To date\, they have sequenced the M. tuberculosis genome from three ancient Peruvians dating to ~1000 years ago. Their analyses indicate that this bacteria likely “jumped” from animals and became a human pathogen within the last 6\,000 years. In addition\, the results show that ancient Peruvian TB strains are distinct from any known human-adapted TB strains and are most closely related to strains adapted to sea mammals. Sea mammals\, specifically Southern Hemisphere seals and sea lions\, acquired strains from other animals in Africa and then within the last 2000 years brought these TB strains to South America.

SUMMARY:Speaking of Sex...
DESCRIPTION:Join anthropologist David Puts as we explore the origins of human sexuality by looking at the evolution of sexual differences in the human voice. \nThe roar of the male lion may indeed scare away his rivals\, but it might also attract female lions looking for a dominant mate. This is sexual selection in action! The lion with the mighty roar might have a few more opportunities to pass along his genes than the lion with the less impressive voice. \nScientists have found that studying the human voice is also a good way to gain insight into human sexual selection.  The human voice is highly differentiated between the sexes\, and the differences are easily quantifiable. Thus it is an ideal model for understanding the evolutionary processes behind our sexual selection.  \nWhy do human males often have deep voices? What does the human female voice signal to potential mates? Join us on February 16th for Being Human: Speaking of Sex…. and learn more about where our voices came from.  \nAge Limit 21+
