Ch 23 Systematics, Phylogenies, & Comparative Biology
By following pathways of similarities and changes—both visible and genetic—scientists seek to map the evolutionary past of how life developed from single-celled organisms to the tremendous collection of creatures that have germinated, crawled, floated, swam, flown, and walked on this planet. The life of a bee is very different from the life of a flower, but the two organisms are related. Both are members the domain Eukarya and have cells containing many similar organelles, genes, and proteins. In scientific terms, the evolutionary history and relationship of an organism or group of organisms is called its phylogeny.
