Analogy – correspondence in function or position of organs of dissimilar evolutionary origin or structure. Apomorphy – derived trait; changed from the original primitive trait. Autotrophic – organism capable of self-nourishment by using inorganic materials as a source of nutrients and using photosynthesis (Plantae). Biostratigraphy – differentiation of sedimentary rock units on the basis of the fossils they contain. Body Fossil – mineralized dinosaur bones. Carpal – cluster of bones between the hand and the arm. Catastrophism – vast geological changes in earth’s history were caused by catastrophes rather than gradual evolutionary processes. Cementation - Clades – a branch or cluster of branches with a common stem on a phyogeny; a monophyletic group. Cladistics – looking at morphological characters (without time) and interpreting phylogeny (cladogram). Clavicle – collar bone. Continental Collision (Uplift) – mountains are created when two continental plates come together. Convergence – similarity of form or structure caused by environment rather than heredity. Deposition - Divergence – evolutionary process by which animals or plants that are descended from a common ancestor evolve into different forms when living under different conditions.
