Cut and Run Legions of athletes, sports gurus, and scientists have tried to figure out why Kenyans dominate long-distance running. In this short, we stumble across a surprising, and sort of terrifying, explanation. At the 1968 summer Olympics in Mexico City, Kipchoge Keino overcame a gall bladder infection to win gold in the 1500 meter race. Since then, one particular group of Kenyans - the Kalenjin - has produced an astonishing number of great long-distance runners. Gregory Warner - NPR's East Africa correspondent - takes Jad and Robert down a rabbit hole of theories about what exactly is going on in Kalenjin country. David Epstein and John Manners help Greg untangle a web of potential factors - from something in the cornmeal to simple economics. Five fingers of evolution - Paul Andersen In his talk, Paul Andersen explains the five causes of microevolution. Research one example for each cause in the human population. Use the following population simulator to simulate microevolution: Run the simulation using the default settings.
Evolution Resources from the National Academies In the News: Your Inner Fish – A Scientific Adventure Have you ever wondered why people look the way they do? Why our hands and feet have five digits instead of six? Why we stand on two legs instead of four?

Short Films “Film is a powerful way to tell stories. … The right story, told well, can be engaging, informative, and memorable.” —Sean B. Carroll HHMI’s series of short films for the classroom brings fascinating stories of science and scientists to students and teachers. The films aim to bring important scientific advances to life with concrete examples of how science works, how evidence is weighed and tested, and how conclusions are reached.
Diseases - Manual - Activity 3, page 1 At a Glance Focus: Students investigate the growth of bacteria in the presence of antibiotics and use the results to explain a case of antibiotic-resistant tuberculosis, presented in an Internet-based interview. Major Concepts: The re-emergence of some diseases can be explained by evolution of the infectious agent (for example, mutations in bacterial genes that confer resistance to antibiotics used to treat the diseases). Objectives: After completing this activity, students will be able to explain how antibiotic treatment results in populations of bacteria that are largely resistant to the antibiotic and describe inappropriate and/or questionable uses of antibiotics. Prerequisite Knowledge: Students should be familiar with bacterial growth and with evolution by natural selection.
