Platypus hunter studies the bizarre mammal’s venom

When she was a child “in the land Down Under,” Camilla Whittington’s dad decided it would be fun for them to go look for platypuses. These animals, found only in Australia, are technically mammals, yet they are like no other mammals around – sure, like all mammals, they produce milk for their babies, but they also lay eggs and have a bill like birds do, and, most oddly, the males shoot venom from spurs in their hind legs that causes pain even the strongest painkillers can’t alleviate.  

WUSTL researchers make discoveries in first collaboration with Libyan scientists

Josh Smith in the Libyan desert.They’re back! Joshua Smith, Ph.D., assistant professor of earth and planetary sciences in Arts & Sciences, and D. Tab Rasmussen, Ph.D., professor of anthropology, both in Arts & Sciences, are stateside, teaching at Washington University after returning from what is thought to be the first-ever collaborative paleontological expedition between American and Libyan scientists. Smith and Rasmussen were in Libya for just three weeks in August of 2005. They were in the field for only 10 days, and they and their colleagues visited 13 new places that have produced Cretaceous-aged vertebrate fossils. They found fossils of sharks, bony fish, crocodiles and turtles.

Survival of the fittest? Anthropologist suggests the nicest prevail — not just the selfish

Are humans inherently good? The prevailing view in popular and scientific literature is that humans and animals are genetically driven to compete for survival, thus making all social interaction inherently selfish. According to this line of reasoning, known as sociobiology, even seemingly unselfish acts of altruism merely represent a species’ strategy to survive and preserve its genes. But Robert W. Sussman, Ph.D., a professor of anthropology in Arts & Sciences at Washington University in St. Louis, argues that this is a narrow and simplistic view of evolutionary theory that fails to explain many aspects of sociality among mammals in general and primates in particular. In “The Origins and Nature of Sociality,” a new book Sussman co-edited, he and other researchers challenge the proponents of sociobiology. “The ‘selfish gene’ hypothesis is inadequate,” Sussman says.
