Document Summary
Preformationism prenatal life starts with a fully formed individual in a sperm or egg, it just getts bigger and stronger over time. Preformationism is patently false new stuff emerges during development=epigenesis. Aristotle took chicken eggs and opened them up at different time in their development to see if new things were forming. Now: scientists can move a cell from one part to another and the cell will change and adapt to where it is place. The beng: newborns get to choose whether they survive or not survive and until they choose they are not alive. Common patterns in biological development you get less specialized first, cells become more specialized over time. Fertilization and conception zona reaction: egg blocks other sperm from entering. Processes of development: cell division, cell migration, cell differentiation: once they migrate they take on whatever is needed for that area, apoptosis. 3 periods of prenatal development ***know for sure for test.
