Evolution for Babies (Baby University) Board book

My 3 year old is in love with these books but this one most of all. I thought it would go completely over her head but the way they use balls to explain the concept of evolution really kept her attention and she asks for the "lotion" book most nights now.

Written by an expert, Evolution for Babies is a colorfully simple introduction to evolutionary biology. Babies (and grownups!) will learn how organisms mutate, evolve, and survive. Co-written by Cara Florance, who has a PhD in Biochemistry and a BS in Chemistry with work experience in astrobiololgy and radiation decontamination. With a tongue-in-cheek approach that adults will love, this installment of the Baby University board book series is the perfect way to introduce basic concepts to even the youngest scientists. After all, it's never too early to become a scientist!
