WebSolution Phylogenetic classification: The classification of organisms on the basis of evolutionary history and the general lineage of organisms is generally called phylogenetic classification. The disadvantages of phylogenetic classification are as follows: WebPhylogenetic bracketing A method of inferring the state of an extinct organism using extant ones. If two species have legs, for example, as do all other species that these two species are related to, we can safely assume that the most recent ancestor that they share had legs, even if we have yet to find fossil evidence of this.
WebPhylogeny is the evolutionary history of a species. § Phylogeny is the evolutionary history of a species or group of related species § For example, a phylogeny shows that legless lizards and snakes evolved from different lineages of legged lizards § The discipline of systematics classifies organisms and determines their evolutionary ... http://www.infogalactic.com/info/Phylogenetic_bracketing
