absorptive heterotroph - An organism (usually a fungus) that obtains its food by secreting digestive enzymes into the environment to break down large food molecules, then absorbing the breakdown products. acidophile - able to live in extremely acidic environments adaptations - inherited aspects of an individual that allow it to outcompete other members of a population that lack the trait; evolve through natural selection Alfred Russel Wallace - came up with a mechanism for evolution simila...

SDSU Anthropology 101 InQuizitive Chapter 11Important changes in the landscape of East Africa and South Africa may have been associated with the rise of Homo habilis and the eventual extinction of the australopithecines. Which of the following statements describe this transition? - correct answer -Underground plant parts (edible roots, etc.) became more important, which increased selection for the use of tools. -Habitat changes correlated with changes in cranial and tooth morphology in Homo h...

adaptions - inherited aspects of an individual that allow it to outcompete other members of a population that lack the trait (or that have a slightly different version of the trait). Adaptions are traits that have evolved through the mechanism of natural selection analogous traits - similar because they have converged on shared form. they are not derived from common ancestor apamorphy - • a form of a derived state Australopithecines - members of the hominin genus Australopithecus biolog...
