Evolution vs. Intelligent Design: Does Homology = Relatedness?

Paternity tests use inherited DNA markers as a way to determine relatedness. So does phylogenetics. If you want to learn to make your own phylograms: http://www.youtube.com/watch?v=e-zH5x02BYQ Here's some resources for more info on phylograms. The Wikipedia article on phylogenetic trees http://en.wikipedia.org/wiki/Phylogenetic_tree Science and Sensibility does a phylogenetic tree of science blogs http://science_boy.blogspot.com/2005/10/testing-evolutionary-hypotheses-and_27.html The Tree of Life web project, based on 16S rDNA sequences http://tolweb.org/accessory/Trees_Based_on_16s_rDNA?acc_id=54 Here's a poster you can order if you love phylogenetics as much as I do. http://www.tellapallet.com/tree_of_life.htm A dendrogram is a broad term for the diagrammatic representation of a phylogenetic tree. A cladogram is a tree formed using cladistic methods. This type of tree only represents a branching pattern, i.e., its branch lengths do not represent time. A phylogram is a phylogenetic tree that explicitly represents number of character changes through its branch lengths. An ultrametric tree or chronogram is a phylogenetic tree that explicitly represents evolutionary time through its branch lengths.
