BIO153H5 Lecture Notes - Lecture 4: Phenology
Document Summary
1: how to talk about the unity and diversity. 2: this graphic gives us the exact message that the naming system should do. The only species that has that name is the polar bear. Fa(cid:373)ily: i(cid:374)(cid:272)ludes all a(cid:374)i(cid:373)als that"s are sort of bear like. Can identify one species, and we have a system where we can classify. System is expandable, can add new species to it: can come up with new names. Highlight how the species comes about, why do we have so many species. First to suggest mechanisms that organisms can change over time. Drew something similar to a tree, kind of like a path. Used a tree like graphic of a phylogenetic tree. Combined two aspects into the tree: 1) classification system 2) species change over time. What is the basic difference between a family tree and a phylogenetic tree family tree.
