To Charlie’s classmates, it seems like the kiwi bird got a raw deal: It barely has wings at all, so it can’t fly, and its long whiskers are more like a cat’s. How can such an unlucky bird even survive in the wild? But Charlie thinks the kiwi is cool, and with the help of his great-great-great-great-great-grandpa Charles Darwin, he travels back in time to learn how the kiwi evolved from a dinosaur-like creature to its present-day wingless state. Learning that “little changes in each generation can add up to BIG changes,” Charlie begins to understand that the kiwi bird’s flightless ways and catlike whiskers might be a bit odd, but they are exactly what has helped the species survive over thousands of years!

Based on an exhibit from the New York Hall of Science that is currently touring the country, this Darwinian adventure through time explains the hugely important principle of evolution in an accessible, kid-friendly style.
