Document Summary

Plant blindness- the inability to notice plants or to recognize their biological importance, rank them inferior to humans and animals. Phylogeny can help us to pinpoint key innovations=adaptations that are linked to diversification of a group. The evolutionary history of a group is known as a phylogeny and a phylogenetic tree is a diagrammatic reconstruction in history. Phylogeny is a hypothesis: created thru observations or genome, use branching diagrams to explain data and distributions of data, the diagram is a hypothesis describing evolutionary history based on these characteristics. Principle of parsimony: simplest explanation, using morphology, maximize number of synapomorphies, you can switch the last two groups. Is a lineages closest relative, in other words, the paired lineage resulting from an evolutionary split. Monophyletic: common ancestor and all descendants. Polyphyletic: group does(cid:374)"t i(cid:374)clude the co(cid:373)(cid:373)o(cid:374) a(cid:374)cestor. Paraphyletic: group includes the common ancestor but not all of the ancestors descendants. Three domains of life: eukaryote, eubacteria, archaea.
