Option 1: Search for sequences and then build a phylogenetic tree. Use the advanced search to allow you to refine your search with the more fine grained.

The research team then used these genomic blueprints to construct a giant evolutionary tree of bacteria based on 120 genes that are highly conserved across the bacterial domain. "This tree helped us.

Introduction. Figure 1: Evolution, a sculpture by Emma de Sigaldi, 1979, located at the Toronto Metro Center. Despite his unique contribution to evolutionary theory—the mechanism of natural selection—Charles Darwin can hardly be considered the first evolutionary theorist in history.

Computational phylogenetics is the application of computational algorithms, methods, and programs to phylogenetic analyses. The goal is to assemble a phylogenetic tree representing a hypothesis about the evolutionary ancestry of a set of genes, species, or other taxa.For example, these techniques have been used to explore the family tree of hominid species and the relationships between.

Locate an "old" evolutionary tree—that is one that was created without the help of molecular biology. (A pre-1995 text book is one good place to find a non-molecular biology evolutionary tree.) Generate a hypothesis for whether or not you think the tree built by protein sequence comparison will match those relationships outlined in this "old" tree.
