Document Summary
Sociobiologists cannot ignore analyses of the learning process. Evolution must be understood as a modification of developmental processes over generations. Male & female pronuclei grow (12 hours) Implantation in the uterine wall: trophoblast cells o blastocyte. Differentiation types all arise from a single cell zygote. : the emergence of structural organization whereby cell types and structures differ from one another. Often wanes or disappears as differentiation progresses. The potential of cells to change their original function this stage only lasts for a certain period of time. Is a process of continual alteration of pre-existing structure within a particular environment. An organism"s structure changes over time as an interactive function of the pre-existing structure, and the environment which the structure is in. Key idea when you think about modern humans. Each structural element in an organism is considered to have its separate precursors idea that it is all genetic determinism the way that an individual develops outdated.
