This shows that divergent evolution allows species with common ancestral origin to be able to adapt to their own habitats. Thus, it is likely to ease competition among them since they evolve traits that make them explicitly suited to their habitat and ecological niche.

What is divergent evolution?
: the development of dissimilar traits or features (as of body structure or behavior) in closely related populations, species, or lineages of common ancestry that typically occupy dissimilar environments or ecological niches The finches that Charles Darwin described in the Galapagos Islands are a classic example of ...
What is divergent evolution explain with the help of example?
Divergent evolution occurs when two different species share a common ancestor but have different characteristics from one another. For example-Flying squirrels and sugar gliders are very similar, yet different. They do not share a common ancestor.
Why is convergent evolution important?
Convergent evolution, then, can serve as a valuable proxy for repeated experiments in evolution, and understanding how convergent traits evolve, especially at the molecular level, has the potential to inform general rules about adaptation [5,6].
Are humans a result of divergent evolution?
A good example of how divergent evolution occurs is in comparing how a human foot evolved to be very different from a monkey's foot, despite their common primate ancestry. It is speculated that a new species (humans) developed because there was no longer was a need for swinging from trees.
What is divergent evolution and convergent evolution?
Divergent evolution occurs when two separate species evolve differently from a common ancestor. ... Convergent evolution occurs when species have different ancestral origins but have developed similar features. A good example of convergent evolution is the similarities between the hummingbird and the hummingbird moth.
What is divergent evolution quizlet?
divergent evolution. a type of evolution in which organisms are thought to have the same ancestor, but separated over time.
How does divergent evolution lead to the evolution of species?
Divergent evolution is the process whereby groups from the same common ancestor evolve and accumulate differences, resulting in the formation of new species. ... Divergent evolution leads to speciation, and works on the basis that there is variation within the gene pool of a population.
Why do species diverge?
Genetic divergence happens because of natural selection, which may favor different traits in each environment, and other evolutionary forces like genetic drift. As they diverge, the groups may evolve traits that act as prezygotic and/or postzygotic barriers to reproduction.
What is chemical evolution life?
The formation of complex organic molecules (see also organic molecule) from simpler inorganic molecules through chemical reactions in the oceans during the early history of the Earth; the first step in the development of life on this planet. The period of chemical evolution lasted less than a billion years.
What is the relevance of homologous structures in studying divergent evolution?
Importance. In divergent evolution, homologous structures are structures indicating a species is diverging from its ancestor. These structures need not have the same function as that of those of the species' ancestors. ... Their similarity in this regard could indicate plausible evolution from a common ancestor.
What does convergent evolution tell us?
Convergent evolution is the independent evolution of similar features in species of different periods or epochs in time. Convergent evolution creates analogous structures that have similar form or function but were not present in the last common ancestor of those groups.
Why adaptive radiation is called convergent evolution?
Adaptive radiation, if occurs twice in a geographically isolated area will have a similar result, that is the evolved species will have similar adaptations suitable for the area. Hence, it will be a case of convergent evolution.
When would divergent evolution occur?
Divergent evolution occurs when a population of animals or plants is split into two groups by a geographic barrier (for instance, a body of water or a migration to a new area), causing each group to develop different traits under their respective selective pressures and natural selection.
Which is a potential consequence of divergent evolution?
An important consequence of divergent evolution is speciation, the divergence of one species into two or more descendant species. There are four major ways speciation can occur: Allopatric speciation occurs when a population becomes separated into two entirely isolated subpopulations.
How does Darwin explain the divergence of species?
Darwin maintained that the origin of species and the evolution of differences between them is ultimately caused by divergent selection acting to minimize competitive interactions between initially similar individuals, populations, and species.
