BIOLOGY 1AL Lecture Notes - Lecture 8: Synapomorphy
Document Summary
Branching patterns depict the history of most of life most species come from common ancestor: a few groups do not have a tree structure, they arise from hybridization, taxonomy and phylogeny, phylogenetic system of classification, all members of a group are each other"s closest relatives, sister taxa abc. Two kinds of similarities: homology similarity due to shared ancestry, ex: forearm of a bat, and forearm of a human, different uses, but same structure, analogy similarity due to convergent evolution, ex: bat"s wing and a bird"s wing, evolved independently, different structure but common use (to fly)
