On a biology field trip near campus,you observe layers of volcanic rock,eroded mountain rocks,and even rocks apparently formed near an ocean coast.Fossils found in the different rock layers have diverse body forms,for living on land,or in the sea,or other habitats.This set of observations tends to support

A) limits to the fossil organism populations, as proposed by Malthus.
B) microevolution of the organisms, as the environment changed.
C) uniformitarianism, as proposed by Hutton.
D) catastrophism, as proposed by Cuvier.
