homologous embryology definition
Embryology is the branch of developmental biology that studies the beginning and early growth of sexually reproducing organisms. This life science specialty focuses primarily on embryogenesis (the formation and development of embryos). In humans, the term embryo is traditionally reserved for the first two months of development. After that point, the term âembryoâ is replaced by the term âfetus,â which then applies until birth. At the beginning of the individualâs development, the entity is a single cell. After two months, it has limbs, distinct fingers and toes, internal development, and countless cells.
Homology involves the theory that macroevolutionary relationships can be proven by the similarity in the anatomy and physiology of different animals. Since Darwin, homology has been cited in textbooks as a major proof for evolution. A review of the literature on homology indicates that the theory does not provide evidence for evolutionary naturalism, and that the common examples of homology can be better explained by Creation.
