Why we study phylogeny? Mobil! A tree is like a mobil! “Tree of Life” (Klimt, Austria) “Tree of Life” project http://tolweb.org/tree/ PHYLOGENETICS In biology, phylogenetics is the study of evolutionary relatedness among various groups of organisms (for example, species or populations), which is discovered through molecular sequencing data and morphological data matrices. The term phylogenetics is of Greek origin from the terms phyle/phylon (φυλή/φῦλον), meaning "tribe, race," and genetikos (γενετικός), meaning "relative to birth" from genesis (γένεσις, "birth"). Taxonomy, the classification, identification, and naming of organisms, has been richly informed by phylogenetics but remains methodologically and logically distinct.[1] The fields overlap however in the science of phylogenetic systematics –often called "cladism" or "cladistics" –, where only phylogenetic trees are used to delimit taxa, which represent groups of lineage-connected individuals.[2] In biological systematics as a whole, phylogenetic analyses have become essential in researching the evolutionary tree of life. • It is a genome world! - The first genome data: Haemophilus influenzae (1995) about 1.8M bp. - Homo sapiens (begun in 1990 and completed in 2001) about 3.3G bp. <$400,000,000 - in 2011, more than 30 plant genomes are determined. • Two examples for the effect of phylogeny in the text book: 1) the phylogeny transformed to systematics (classifications) 16S rDNA phylogeny: suggested three domains in the life. 2) the phylogeny showed evolutionary information HIV gene (env) phylogeny: gave evidence of infection pathway. HIV genome stored evolutionary information recount the very recent history of its spread. ► Not only just pure application to the systematics but also the tracing evolutionary history.
