This is part of a series of video guides through the evolutionary tree of life, meant to be associated with the Phylogeny Explorer Project. Here is a link to the entire series playlist.    • Systematic Classification of Life   The Systematic Classification of Life started as a discussion with creationists on Christian Forums. The discussion convinced one of them of the reality of evolution. She eventually became my wife. Lilandra proposed a video series on that discussion to help people appreciate the beauty and scientific power of cladistics or common ancestry. The original discussion is the template that is being expanded on with my wife's help.
