When birds first evolved.
Adult amphibians
are carnivores/predators in the food chain.
3 orders of organisms in class Chondrichthyes
sharks, skates & rays, ratfish
Early Birds

evolved from amphibians (Labryinthodont)
Class Reptiles
internal fertilization, eggs, lungs, scales. Reptiles would most likely survive in the desert.
2 members of Class Agnatha

Lobe-finned fish
evolved from amphibians
Organisms with bodies that are warmed by heat generated by metabolism. This heat is usually used to maintain a relatively stable body temperature higher than that of the external environment.
New Zealand and Madagascar

mammals that lay eggs. They also have mammary glands, imperfect temperature regulation and a cloaca.
evoloved from land dwelling carnivores.

Convergent Evolution
process by which unrelated organisms independently evolve similarities when adapting to similar environments.
have lower jaw composed from just one bone.
structure through which feces, urine and gametes pass.
4 types of mammal teeth
incisors, canines, pre-molars, molars
