This sturdy 24x36" wallchart is unique in that it serves as both a timeline of evolution and a guide to biological classification. Over 250 plant, animal, and microbe species are arranged according to the most up-to-date taxonomy (domain, kingdom, phylum, order, family, and genus) in a beautiful, easy to follow "tree of life" format. The chart focuses on species that are well-known to the average person so that one can discover interesting things such as the fact that green peppers are closely related to petunias or that dolphins are closely related to barnyard animals.
