Other noteworthy things about this series not mentioned in my review of the Biology book
Simon Basher, the illustrator, originated this concept series in the UK for Toucan Books, and now published in the US by a Macmillan imprint.
Dan Green is the series writer.
Each title has a scientist consultant, this one James Valles at Brown University.
As with many smaller books, I question the need for a Table of Contents and Index in this series. It seems like one of those things the editors and publishers probably told Basher he needed and he just said OK. It would be interesting to see if this is something that was just added for the US publication
