Document Summary

What are they and what other landmasses resulted from the further breakup of these two new land masses: gondwana -> south america, africa, antarctica, australia. Laurasia -> north america, europe, asia: gondwana -> north america, europe, asia. Laurasia -> south america, africa, antarctica, australia: gondwana -> tethys, australasian. Laurasia -> arabia, antarctica, siberia: eurasia -> beringia, north america, europe. If you need to write more than the area allotted, finish the answer on the back of the page: (6 pts) why is crypsis less likely than aposematism to be an example of co-evolution. Crysis is when a prey or predator species evolves coloration that helps it to blend into the environment and make detection difficult. Crypsis is generally one sided, since the direction of evolution of traits is dependent on the environment, which does not evolve in response. Thus it is not likely to be an example of coevolution.
