Document Summary
4. 1 variation: humans exhibit variation in skeletal and dental morphology, bone chemistry, and. There is variation between males and females in size, shape and size-dependent shape. A typological approach, one that employs typology (the practice of choosing one individual to characterize a whole species), without consideration of the normal range of variation can result in misguided and inaccurate taxonomies, or species identifications. > variation is the most important component of learning evolution. 4. 2 facts about bone: bone is a relatively light-weight, yet very strong, material that is a composite of collagen (which is essentially protein) and mineral (hydroxyapatite-> a form of calcium phosphate). Bone is living and dynamic tissue which is able to regenerate itself: the skeleton is subjected daily to mechanical forces such as compression, bending, shear, and torsion. Bone is deposited where it is needed and resorbed where it is not (wolff"s law).
