please welcome eliot schrefer! or: i am so happy to have you. this is one to have the most fun books i've ever read about science, nature, animals, the human condition. let's jump straight into it. "queer ducks (and other animals)." this seems like a joke. the book is very funny, which is great, butyou're learning about a side of the animal kingdom many haven't talked about. why did you decide to write a book at queer ducks and other animals? >> fair enough. i was surprised by the topic, too. i come from a background of studying evolution and i always assumed that queer behavior was a sort of dead end for animals, that behaviors that wouldn't cause their genes to propagate into their next generation wouldn't spread, yet nature did a study three years ago that put the number at 1500 species and counting that have significant peer researched same-sex sexual behavior in the wild. the question on my mind is why is this happening? and the basic version of the story is we got the story of animal sex wrong. >> trevor: you
