Essay on Biology

Developmental biology is a biological field that was started with Aristotle and right now is leading to modern analysis and techniques. The article has given thought to the reasons for genetics being more reviewed and examined rather than developmental biology. It has given rise to many biological fields such as genetics, cell biology, oncology, immunology, and neurobiology. Basically, genetics has taken over developmental biology in the way to analyzing different biological fields. Geneticist believes developmental biology is esoteric and irrational. Developmental biology was condemned due to its vastness as this subject was not regarded as a specialized field likewise other biological branches. This field has a broad research area with important interdisciplinary crossovers.

Developmental biology is not restricted to any levels of organization that as cell tissue, organ, individual, and ecosphere. Developmental biology does not get the credit it deserves for its contribution to understanding the natural world. It remains undifferentiated while the successor fields are more confined. New disciplines are striving to arise from developmental biology. Stem cell biology is more debatable rather than being logical so it’s yet to be divided. Different biologists challenge over biodiversity caused by variation in embryogenesis.

Geneticists argued that the study of different species inheritance was the factual advancement towards evolution. They concluded embryology and paleontology was an illogical approach to study evolution. Oncologist claimed that cancer should be dealt with as a fault in embryonic development because cancer showed similar law which managed development. Geneticists presume supremacy over the discipline of oncology in a similar fashion with evolutionary biology. Boveri related abnormality of cancer to developmental defects caused by polyspermy and by chromosome elimination during nematode growth concluded chromosomal rearrangement was origin of originating cancer. This leads to a result that developmental biology ease in construction of cancer biology. Ross Granville Harrison conducted tissue culture experiments to work out the problem by presenting embryogenesis of frog soma expanded a larger neurite.

In neurobiology, his colleagues indicated signaling’s role in finalizing synapse completion which lead axons to its desired goal. Harrison resolved the issue by describing the neural connections of the human body. Then geneticists presumed superiority over the discipline of oncology similar to evolutionary biology and neurobiology. Ecological developmental biology spot the influence of environment on embryo growth. Woodger and von Bertalanffy tried to merge embryology, ecology and system biology together into the consolidative emerging science of new era. Although there is an argument related to genetics dominance over developmental biology but it still remains an important branch of science. The induced pluripotential stem cells are figure out by propositions of developmental biologists. The new discoveries such as study and function of the Zika virus and the three-dimensional arrangement of chromatin. This field is enlarging by recognizing the connection of zygote cells of the embryo and mutual microbes to make gut, capillary and immune cells. In this century developmental biology has undergone many transformations since its emergence. The comeback of developmental biology to its deserved position to study other biological disciplines. This branch of biological science is becoming a backbone of interlinking biological fields.
