analogous structures: Structures in different species that look alike or perform similar functions (e.g., the wings of butterflies and the wings of birds) that have evolved convergently but do not develop from similar groups of embryological tissues, and that have not evolved from similar structures known to be shared by common ancestors. Note: The recent discovery of deep genetic homologies has brought new interest, new information, and discussion to the classical concepts of analogous and homologous structures.anatomy: (1) The structure of an organism or one of its parts. ancestral homology: Homology that evolved before the common ancestor of a set of species, and which is present in other species outside that set of species. anthropoid: A member of the group of primates made up of monkeys, apes, and humans.amphibians: The class of vertebrates that contains the frogs, toads, newts, and salamanders.The amphibians evolved in the Devonian period (about 370 million years ago) as the first vertebrates to occupy the land.ammonoid: Extinct relatives of cephalopods (squid, octopi, and chambered nautiluses), these mollusks had coiled shells and are found in the fossil record of the Cretaceous period.

antibiotics: Substances that destroy or inhibit the growth of microorganisms, particularly disease-causing bacteria.They have moist scaleless skin which is used to supplement the lungs in gas exchange.The eggs are soft and vulnerable to drying, therefore reproduction commonly occurs in water.The term can also be applied to larger groups of organisms, as in "the adaptive radiation of mammals." adaptive strategies: A mode of coping with competition or environmental conditions on an evolutionary time scale.Species adapt when succeeding generations emphasize beneficial characteristics.
