Who: Dan Riskin
Age: 36
Experience: When he was in high school, his mom bought him a book about bats from the Alberta museum. After a few pages, Riskin couldn’t put Just Bats down, as he was consumed with what most of us would consider biological minutiae, like the fact that male bats have testes with a mass about eight per cent of their bodies. Years later, after completing a BSc. at the University of Alberta and a MSc. at York University (where his advisor was M. Brock Fenton, bat biologist and the author of Just Bats) Riskin earned a doctorate in zoology from Cornell University and did post doctoral work at Brown University. Before he could accept a faculty position, a TV producer learned about his enthusiasm through word-of-mouth and he was offered the opportunity to host Monsters Inside Me, a show about parasites on Discovery Science, which he continues to host. Currently, he’s also the co-host of Daily Planet, a science news show on Discovery Channel.
“The Australian bowerbird’s nest has got this bower, sort of like those ugly wicker arches used for getting married in a field. And the males collect blue things, because they are hard to find, and they impress girls with them. So, if you had a lid from a Bic pen, or a blue thumbtack or whatever, they’ll collect them in front of their bower. He’s not saying the blue things are valuable. He’s saying: ‘I’m so good at being a bird and staying alive that I can go and waste my time on stupid blue things and I still have enough energy left to go and do other things.’ Using energy to find blue things is as vital as avoiding predators.”
“There have been cases where people have cut off a peacock’s tail and the peacocks are healthier, they get more food, they spend less energy on flying. Everything is easier for them. But the girls [peahens] aren’t attracted to them without the tail. When they have the big tail, they pay a cost for it, but the ladies love it. The fact that it costs something to make it is kind of an accurate measurement of how much extra energy they have.”
