Evolutionary biology is the field of biology that studies the evolutionary processes that produce the diversity of life on Earth. Simply put, it is also described as a study of the history of species on Earth. Evolution is based on the theory that all species are related and that they evolve over time. In society, genetic variation affects the physical characteristics of living phenotypes. These mutations in phenotypes will benefit other species, which will then be passed on to their offspring. The Peppered Moth and the Flightless birds are just some examples of the many different kinds of evolution that occur over many generations. The theory of evolutionary biology arose from modern integration of understanding, from previously unrelated fields of biological research, such as genetics and ecology, systematics, and paleontology. The importance of studying Evolutionary biology is primarily to understand the principles of evolution and extinction of species. The current research list has been expanded to include genetically modified genes, molecular evolution, and the various forces that contribute to evolution, such as sex selection, genetic predisposition, and biogeography. In addition, a new field of evolutionary development biology is investigating how embryogenesis, embryonic development, is regulated, thus producing a broader integration of biological development and research fields covered by previous evolutionary combinations. One approach is the level of biological organization, from cell to cell, living to humans. The former approach is to be a hypothetical taxonomic group, with fields such as animal science, botany, and microbiology, reflecting what has been considered major stages of life. The third method is to use methods, such as field biology, theory biology, experimental evolution, and paleontology. These alternative methods of classification can be combined with evolutionary biology to create sub-fields such as evolutionary ecology and evolutionary developmental biology. More recently, the link between biology and applied science has given birth to new fields of evolutionary science, including robots of engineering, algorithms, economics, and architecture. Basic evolutionary methods are used directly or indirectly to come up with novel designs or problem-solving that are difficult to solve in some other way. The research produced in these applied fields, also contributes to the process, mainly due to the evolutionary work in the field of computer science and mechanical engineering. Similarly, birds, insects, and bats all have the ability to fly, but they are not related. The influence of two closely related species is known as co-evolution. When two or more species evolve into other species, one species adapts to other species. This type of evolution usually occurs in species with symbiotic relationships. For example, predator-prey coevolution, this is the most common form of evolution. In this case, the invader has to change to become a more effective hunter because of the selective pressure on the predator to avoid being caught. Likewise, the relationships between pollinating insects such as bees and flowering plants, herbivores and plants, are also common examples. Evolutionary dynamics is related to the evolutionary process that occurs as a result of evolution, making the living thing fit into its habitat. These changes increase the chances of survival and reproduction of an organism. In evolutionary development biology, the various processes involved in evolution can play a role in how a living thing reaches its present system. The genetic control of ontogeny and the phylogenetic process are what allow this kind of biological understanding to take place. If you look at the different processes during development, and walk through the tree of evolution, one can decide when a particular building came into existence. For example, three layers of germs can be seen to be absent from cnidarians and ctenophores, instead they are found in worms, which grow slowly depending on the type of worm itself. Other structures such as the structure of the Hox gene and the optic nerve-like organs may also be traced to this practice.
