Question

What is Evolutionary Developmental Biology (Evo-Devo)? Explain how this new field is different from experimental embryology and evolutionary biology.

Answer 1

Evolutionary Developmental biology

evolutionary Developmental biology is made up of two words Evolution that means evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection. The theory of evolution is based on the idea that all species are related and gradually change over time. and the development is the evolution that can be checked with the perspective of the development of the organism. evolutionary Developmental biology is referred to as the advancement in evolutionary biology to know the evolution by means of organisms Developmental in the environment from before its birth or the study that compares the developmental processes of different organisms to infer the ancestral relationships between them and how developmental processes evolved. Evolutionary developmental biology is that part of modern biology concerned with how variable changes occur in embryonic development during single generations related to the evolutionary changes that occur between generations. Charles Darwin argued for the importance of development (embryology) in understanding evolution Mendel experiment can not gives exact ideas about the evolution in the related species o know the evolution scientist takes the help of embryology.

Charles Darwin suggested that the genetically same species which are now in different morphology and variation are due to any kind of reason shows different habitats but the species which can genetically relate in the past which shows the same kind of embryonic structure when they develop. by the example of spherical eggs of different animals give rise to extremely different bodies, from jellyfish to lobsters, butterflies to elephants. Many of these organisms share the same structural genes for body-building proteins like collagen and enzymes, but biologists had expected that each group of animals would have its own rules of development. The surprise of evo-devo is that the shaping of bodies is controlled by a rather small percentage of genes and that these regulatory genes are ancient, shared by all animals.

the evolutionary developmental biology is the combination of both developmental biology and the evolution Charles darwin can give us the idea about the natural selection for the evolution but to check the evolution we need to proves and that proves which are given by the specific studies of developmental biology as the genetically related species by observing the embryo development and its stages. the evolutionary developmental biology comes to existence due to the relation of the species with its ancestor and their genetic related species is by the development. development pattern before the birth of the genetically related organism is really the same that they carry the same pattern from the past.

in nutshell many embryological states that the growth of the characteristic of the embryo is going to help the scientist to arrange grouping the phyla and subphyla.

the difference in the evolutionary developmental biology from both experimental embryology and the evolutionary biology is to it gives an idea of evolution in by the development and that two fields are working the same but differently the evolutionary biology has many factors to prove the evolution like fossils flora fossils fauna and that is supported by the developmental biology to learn the evolution in the organism by the new field evolutionary developmental biology.
