Ants have evolved ingenious solutions to nature’s problems.  They are farmers, trappers, builders, herders, gliders, water-walkers, and much more.  Perhaps most interesting of all – like humans, they form complex societies that function with no central control.  We explore the many oddities of the ant world.

Sexual conflict and female revolution in damselflies

Among the ponds of the Brackenridge Field Laboratory lurks the living evidence of a multi-million year struggle between males and females.  Find out how the battle between the sexes contributes to evolution, and why some female damselflies at Brackenridge look suspiciously like males…

Deep Sea Exploration

People seeking challenges have a tendency to look up into the sky more than below their feet. This is perhaps why the deep ocean largely remains a mystery. I will review the methods currently used for deep-sea research, tell some stories from my personal experience, and tell about our recent discovery at 3000 ft depth that is perhaps the best illustration of the unexpected things that can be found down there.

Seeing It As It Happens:  Witnessing, controlling, and understanding evolution

How do scientists discover how evolution affects a group of organisms?  By doing what scientists do best — experimenting and recording the results!  Join us as we talk about how scientists control the environment of bacteria, viruses, and insects to learn more about evolution.  We will also talk about how people use evolution to improve computers, crops, pets, and clean up the environment.
