Document Summary
Disparity vs. diversity: animal multicellular, eukaryotic, heterotrophic, motile, lack cell walls (metazoans, diversity having different forms or types, disparity morphological differences between various taxa, diversity the (cid:498)counts(cid:499) of taxa. Why study animal diversity: evolution (paleontology and origin), taxonomy, ecology and animal architecture (form and function), new science, conservation, what makes groups similar or different. Edward o wilson the father of biodiversity. What is ecology: coined by ernst haeckel in 1866. Levels of ecology: how the animal responds to the environment and lives in its habitat or niche. Key transitions: levels of organization/complexity (tissues, body symmetry, body cavity organization, developmental traits, protostome vs. deuterostome. Recap: protostomes vs deuterostomes: based on embryonic development, protostome spiral cleavage, deuterostrome radial cleavage, protostome mouth first, deuterostrome anus first, different formation of coelom. Splits of animal groups: porifera, placozoa, bilateria radiate, protostomia, lophotrochozoa, ecdysozoa, deuterostomia (gill slits) Hiearchial groupings: kingdom - animalia, order mammalia, phylum chordata, class vertebrata, family hominidae, genus homo.
