Tree of Life Web Project
Collaborative Internet project containing information about phylogeny and biodiversity.
Lists phylogeny packages and free servers classified by their methods, computer systems they work on, and what type of data the are designed to handle.
Introduction to Phylogeny
Looks at the ancestor/descendant relationships which connect all organisms that have ever lived.
Journey Into Phylogenetic Systematics
All about cladistics and the way that biologists reconstruct the pattern of events that have led to the distribution and diversity of life.
Includes societies, meetings, publications, databases, software, and more.
Phylogenetic Systematics, a.k.a. Evolutionary Trees
tutorial from the Understanding Evolution website covering: how to read an evolutionary tree, how to classify organisms based on evolutionary trees, how to reconstruct an evolutionary tree, and how evolutionary trees are used.
Systematics and Molecular Phylogenetics
Learn how scientists reconstruct evolutionary pathways using computerized applications in this basic introduction from the National Center for Biotechnology Information.
Ensatina eschscholtzi: Speciation in Progress
Classic example of Darwinian evolution. This lungless salamander is now in the process of splitting into two or more species by means of gradualism.
