Document Summary
How to build phylogenetic tree (parsimony, maximum likelihood) Types of phylogenetic trees (cladograms, phylograms, ultrametric trees) The fossil record provides information about the history and relationships among organisms. Is based on the sequence in which fossils have accumulated in such strata. Fossils reveal: ancestral characteristics that may have been lost over time. Fossils dates: provide minimum estimates of the age of a taxon. But the history of organisms is also written in their features, and in their genes. Phylogenetic systematics connects classification with evolutionary history. Is the ordered division of organisms into categories based on a set of characteristics used to assess similarities and differences.
