About

Game designer Jonathan Tweet and children’s science illustrator Karen Lewis collaborate on original evolution projects for kids.

Grandmother Fish is a child’s first book of evolution. The book engages a young child’s imagination with sounds and motions that imitate animals, especially our direct ancestors: a fish, a reptile, a mammal, an ape, and a human. The book lets children see for themselves that we are related in form and function to the animals that preceded us. It’s our story of where we came from, told so simply that a preschooler can follow it. Wiggle like a fish! Hoot like an ape! Tweet and Lewis self-published in 2015 and sold out. Now Macmillan has released their own edition (2016). School Library Journal calls it “groundbreaking.”

Clades and Clades Prehistoric are animal-matching games that teach evolutionary relationships among animals. A clade is a complete branch of the evolutionary family tree, such as “mammals.” Clades features living animals, while Clades Prehistoric features extinct species. For ages 6+, published by Atlas Games of St. Paul, Minnesota.
