Lesson 14 in Friendly Biology introduces how living things have been divided into various groups and subgroups (which is known as taxonomy). When Friendly Biology was written in 2012, Lesson 14 utilized The Catalogue of Life website to illustrate many of the concepts found in the lesson. Since that time, The Catalogue of Life website has been changed and it no longer corresponds to the images used in Friendly Biology. We suggest that you utilize Lesson 14 as written and not expect to find similar screens on The Catalogue of Life website. Instead, following completion of the lesson, we encourage you visit The Catalogue of Life website to learn more about taxonomy and how the database can be useful for further study.
