WebAnnoTree - is an interactive, functionally annotated bacterial tree of life that integrates taxonomic, phylogenetic and functional annotation data from over 27 000 bacterial and 1500 archaeal genomes. WebParsimony analysis aims at finding the tree that best fits hypotheses of homology. However, parsimony does not directly maximize homology, but minimizes homoplasy. When a parsimony analysis results in more than a single most-parsimonious tree (MPT), it is shown that the number of homologous characters may vary significantly.
WebA homoplasy is a character shared across clades in a phylogeny that don’t share direct ancestry, are an indication of inconsistency between the phylogenetic tree and the sequences used to build it. Which are causes of homoplasy? In the case of DNA sequences, homoplasy is very common due to the redundancy of the genetic code. The word homology, coined in about 1656, is derived from the Greek ὁμόλογος homologos from ὁμός homos "same" and λόγος logos "relation". Similar biological structures or sequences in different taxa are homologous if they are derived from a common ancestor. Homology thus implies divergent evolution. For example, many insects (such as dragonflies) possess two pairs of flying wings

WebWhen we are building a phylogenetic tree from a dataset, our goal is to use shared derived traits in present-day species to infer the branching pattern of their evolutionary history. The trick, however, is that we can’t watch our species of interest evolving and see when new traits arose in each lineage. Instead, we have to work backwards.
