what caused the cambrian explosion what adaption appear in the fossil of the cambrian period.
Homework Answers
The main reason behind cambrian explosion is considered to be the sudden increase in oxygen levels which triggered the evolution of more complexity in life and driven most of the exiting species to extinction. The other regions might also influenced are ozone formation, glaciation, increase in calcium concentration on sea water etc
Cambrian explosion accounts for the fossil record of appearence of major animal phyla, during this period earth vitness the dramatic burst in evolutionary changes on earth. The major shift or adaptation considered to be appearence of complex organisms with minaralised skeleton systems.

a. First, discuss three causes for the Cambrian explosion. Then address this question: Multicellularity evolved right before the Cambrian explosion; how do you think multicellularity enabled the Cambrian explosion (base your response on our discussion regarding the evolution of multicellularity). b. Evolution has produced interesting scaling relationships between energy use and body size. Why was it predicted that the scaling relationship of metabolic rate to body size is 2/3? Why is the scaling relationship closer to 3/4? Prove that you...
