For the past two decades, Kay E. Holekamp has been chronicling the lives of spotted hyenas on the savannas of southern Kenya. She has watched cubs emerge from their dens and take their place in the hyena hierarchy; she has seen alliances form and collapse. She has observed clan wars, in which dozens of hyenas have joined together to defend their hunting grounds against invaders.
“It’s like following a soap opera,” said Dr. Holekamp, a professor at Michigan State University.

My talk last week at Carleton University in Ottawa went well–here’s an interview with the university’s magazine, and here’s a report from someone in the audience.
More talks are coming up–
Next week: The evolution of whales at Mote Marine Laboratory in Sarasota, Florida.
Next month: Soul Made Flesh at the University of Denver.
And plenty more coming in May and June…
