Slide 4 - Chordate Characteristics
Slide 5 - Gills in Humans! – check it out
Slide 6 - Tunicates are Chordates! Sea Squirts sponge like - filter feeder larva free swimming, bilateral with all Chordate traits
Slide 7 - Lancets (a primitive fish like organism) closely resembles the idealized chordate. The notochord, dorsal nerve cord, numerous gill slits, and post-anal tail all persist in the adult Copyright © 2002 Pearson Education, Inc., publishing as Benjamin Cummings

Slide 10 - Chp 33 – Rise of the Mammals Definition of a Mammal: Homoeothermic – meaning that mammals produce their own body heat Mammary tissue - for the production of Milk Hair Follicles - for the production of Hair Generally, internal fertilization and harboring of young, however, this is only a generality because not all young are “cooked” to term internally.
Slide 11 - Monotremes – an Order of Class Mammalia Monotremes eg. The Platypus, which has a BILL, lays EGGS, but still has mammary glands and produces MILK for young. This suggests a relationship between REPTILES, BIRDS and mammals. Imagine that?
Slide 12 - Marsupials – eg. The Kangaroo, which is a non-placental mammal. Here, the development of the young is very complex, and a baby kangaroo is born very “uncooked”, and must crawl into the mother’s pouch and latch onto a nipple to receive milk to continue development. You might say, baby Kangaroos or “Joey’s” get a womb with a view 
