It has the following characteristics: external "armor" of bony plates; no paired fins; and a suspension-feeding mode of nutrition. In addition to these characteristics, it will probably have which of the following characteristics? 1)legs 2)no jaws 3)an amniotic egg 4)metamorphosis 5)endothermy
Copyright © 2005 Pearson Education, Inc. publishing as Benjamin Cummings 3.Why is the amniotic egg considered an important evolutionary breakthrough? It * 1)has a shell that increases gas exchange. 2)allows incubation of eggs in a terrestrial environment. 3)prolongs embryonic development. 4)provides insulation to conserve heat energy. 5)permits internal fertilization to be replaced by external fertilization.

Copyright © 2005 Pearson Education, Inc. publishing as Benjamin Cummings 5.Which of these statements about human evolution is true? 1)The ancestors of Homo sapiens were chimpanzees and other apes. 2)Human evolution has proceeded in an orderly fashion from an ancestral anthropoid to Homo sapiens. 3)The evolution of upright posture and enlarged brain occurred simultaneously. 4)Different features have evolved at different rates. 5)Mitochondrial DNA analysis indicates that modern humans are genetically very similar to Neanderthals.
