While in divergence, one population evolves separately to form different characteristics. However, this divergence is so drastic, that the two species now have very little in common. Convergent evolution occurs in the organisms which are not closely related, while Divergent evolution is shown in the organisms which are closely related. 2. However, for the ease of understanding, I will first explain divergent evolution and then move onto convergent evolution. Divergent evolution demonstrates how species can have common (homologous) anatomical structures which have evolved for different purposes.

Natural selection is more of an outcome of natural pressure that organisms find themselves subjected to (typically pressure of competition, pressure of meet the mating preferences of the opposite sex, etc.) Among the Galápagosfinches, for instance, beak shape changed (or diverged) to better match the different types of food available on various isl… Now, can it not happen that the orange eating species eventually diverged into banana-eating species, just the way the apple-eating species did? Convergent evolution is a type of evolution that explains how phylogenetically unrelated organisms show similar traits and physiological processes. 1.” Convergent Evolution.” Boundless. Divergence makes sense only in the light of ‘gradualism‘. We hope you are enjoying Biologywise! So, divergent evolution is the creation of new species through accumulation of many small ‘changes’ that have originated as a result of the natural selective pressures. Continue reading for a simplified understanding. The Convergent example asks for a vehicle, What is questioning? In convergent evolution, organisms share physical similarities that can be seen because they . Thus, the environment forces the phenotype of distantly related organisms to become analogous. https://vivadifferences.com/convergent-vs-divergent-evolution This following BiologyWise article will take you through a brief explanation of the theory of evolution by Charles Darwin. Three main differences between convergent and divergent evolution are: 1. 1. Using the same example of monkeys, apples and bananas – if you want bears competing for apples to also evolve into banana-eating bears, they should be posed with the same amount of competition as the monkeys; only then will two different species (monkeys and bears) evolve towards the same fate (going bananas!). However, the article provides a core difference between convergent and divergent evolution in a tabular form for easier understanding. Thus, divergent evolution is a process of macroevolution, creating more diversity of species in the biosphere. The forelimb structures of several vertebrates are shown in figure 2. The American naturalist J. T. Gul Gradualism is what ensures that two new species will diverge and not converge. Answer Questions. Start studying Convergent and Divergent Evolution. In convergent evolution, analogous structures are developed in distantly related species, which live in the same environment. If a boulder were to obstruct its flow into a crevice, it would take a turn around the crevice. There is a large number of species that exist in this universe. answer choices . a.) On the other hand, penguins and ostriches are both flightless birds, both of which have evolved to walk on the ground. mrsbethhoward. The mechanism of evolution can be parallel evolution, convergent evolution, and divergent evolution. Yet they have both adapted to fly. Convergent Evolution: Convergent evolution describes different species that don’t have a common ancestor (unlike divergent evolution), but ended up with similar traits and features anyways; possibly because they live in similar climates, environments, etc. Birds and butterflies are an example of what? If this were to happen, one of the two species would in fact be driven to extinction. Most of the time, the reason behind convergent evolution occurring is the build-up of adaptations over time to fill a certain niche . This is exactly what divergent evolution is all about. a.) Key Difference – Adaptive Radiation vs Divergent Evolution Adaptive radiation and divergent evolution are two processes related to speciation and evolution.Both these processes involve diversification of a species from a common ancestor. Convergent evolution creates analogous structures that have similar form or function but were not present in the last common ancestor of those groups. Both convergent and divergent evolution have contributed to the development of present organisms from the past organisms. Consequentially they would both split into two smaller independent rivers. Organisms develop analogous … The environment selects similar adaptations in unrelated species. Convergent Evolution: Both species live within the same environment. Natural disasters such as volcanos, changings of the climate, and spread of diseases may cause the divergent evolution. The evolution process may occur in two different forms, either through convergent or divergent evolution. Of the several confusions that persist in the field of evolutionary biology, one is that about convergent and divergent evolution. What is the Difference Between Relative Dating and... What is the Difference Between Gracile and Robust. Popularized in the late 1800s by American missionary and naturalist J. T. Gulick, the term describes one single species becoming many to fit different roles in a given setting. 2. Convergent Evolution vs. Divergent Evolution. answer choices . convergent c.) co d.) it is not evolution 2.)
