BIOL 101 Lecture Notes - Lecture 12: Cambrian Explosion, Chromosome, Regional Differentiation
Document Summary
Evolutionary developmental biology (informally, evo-devo) is a field of biology that compares the developmental processes of different organisms to determine the ancestral relationship between them. Modifications of development and developmental processes lead to the production of novel features the role of developmental plasticity in evolution how ecology impacts development and evolutionary change developmental basis of homoplasy and homology. The study of the process by which animals and plants grow and develop, and is synonymous with ontogeny. Main processes involved in the embryonic development of animals are: regional specification. Morphogenesis cell differentiation, growth overall control of timing. Segmentation condition of being constructed of a linear series of repeating parts, each being a metamere (body segment, or somite) and each being formed in sequence in the embryo, from anterior to posterior. The genes controlling segment formation during embryo development are almost identical in the fruit fly (an arthropod) and in annelid marine worms (an annelid).
