Many children's books and songs double as mini-lessons in counting (One Elephant), letters (the alphabet song) or fine-motor skills (Thumbkin). It's less common to find such activities for young children infused with basic science.
Take evolution. Perhaps it hasn't made it into classic nursery rhymes because it's all about sex and death — not the easiest topics to discuss with little folks. It's also challenging for adults to understand and accept, in part because a solid understanding of evolution rests on some pretty sophisticated concepts, including deep time and probability.
So I have great admiration for recent efforts to make evolution more accessible to young, inquiring minds. Grandmother Fish, for example, is a Kickstarter campaign (on track to be funded next week) that aims to produce "a child's first book of evolution," with a focus on communicating the idea of common descent. Great Adaptations is a book targeting older children, with contributions from a variety of scientists and illustrators showcasing biological adaptations.
But as far as I can tell, the burning need for a nursery rhyme about natural selection remains to be met. And I'm here to rise to the challenge. I offer — only half in jest — alternative lyrics to the classic Five Little Monkeys, fully uncensored, sex-and-death style. Thanks to two co-conspirators, Elizabeth Bonawitz and Tom Griffiths, you can appreciate it in full audiovisual grandeur:
