which of the following is an example of divergent evolution course hero

What is an example of divergent evolution according to Darwin?

Darwin’s Finches. One of the most famous examples of divergent evolution was observed by Charles Darwin, and documented in his book On the Origin of Species. Upon visiting the Galapagos Islands, Darwin noted that each of the islands had a resident population of finches belonging to the same taxonomic family.

What is an example of convergent evolution in biology?

Real-life examples of convergent evolution include the body shape and color of sharks and dolphins and the different, yet functionally similar, wings of birds, bats, and bees. To unlock this lesson you must be a Study.com Member.

What is the relationship between speciation and divergent evolution?

Divergent evolution leads to speciation, and works on the basis that there is variation within the gene pool of a population.

What is an example of evolution in station 1?

Station 1 (Types of Evolution) 1. A group of mice becomes separated by the formation of a river. Over time, the northern mice became smaller and whiter, while the southern mice became larger and browner. This is an example of: a. divergence

Why does divergent evolution occur?

Alternatively, divergent evolution may take place in response to changes in biotic factors, such as increased or decreased pressure from competition or predation. As selective pressures are placed upon organisms, they must develop adaptive traits in order to survive and maintain their reproductive fitness. Differences may be minor, such as the ...

Which scientist observed divergent evolution?

Darwin’s Finches. One of the most famous examples of divergent evolution was observed by Charles Darwin, and documented in his book On the Origin of Species. Upon visiting the Galapagos Islands, Darwin noted that each of the islands had a resident population of finches belonging to the same taxonomic family.

What are the structures present in the common ancestor of two species and that persist in their evolved lineage?

The structures present in the common ancestor of two species and that persist in their evolved lineage, albeit with a different form or function, are known as:#N#A. Analogous Structures#N#B. Homologous Structures#N#C. Divergent Structures#N#D. Vestigial Structures

What is the case of Darwin's finches?

The case of ‘Darwin’s Finches’ (the birds actually belong to the tanager family and are not true finches) is an example of adaptive radiation, which is a form of divergent evolution. Darwin’s finches. Adaptive radiation is a common feature in archipelagos such as the Galapagos Islands and Hawaii, as well as on metaphorical ‘island habitats’ such as ...

What happens when a reproductive barrier separates two groups within a population?

If a reproductive barrier separates two groups within a population, different genes controlling for various aspects of an organism ’s ability to survive and reproduce increase or decrease in frequency as gene flow is restricted. Allopatric speciation and peripatric speciation occur when the reproductive barrier is caused by a physical ...

What is a small-brained, small-bodied, and relatively small-bodied animal?

These are small-brained and relatively small-bodied, with a wet nose similar to that of a dog. They are often nocturnal, with body features that are considered ‘primitive’, compared to other primates. The next big divergence occurred around 35 million years ago in the other phylogenetic branch of primates, the simians.

What is it called when an organism evolves analogous structures with similar appearances?

This is known as convergent evolution.

What is divergent radiation?

Divergent (Adaptive Radiation)- 2 or more of the same species become dissimilar because of environment. (Darwins finches) (artificial selection in dogs) Station 1 (Types of Evolution) 1. A group of mice becomes separated by the formation of a river.

How does evolution occur?

According to Darwin's theory of evolution, evolution occurs through natural selection operating on populations in ecosystems. - Overproduction- produce more than will survive to insure genes will be passed on. - Competition- better competitor will pass on genes. - Variation- diversity allows for selection.

What is the term for the gradual change of organisms over very long periods of time?

Evolution (Macroevolution) Gradual change of organisms over very long periods of time. Types of Evolution- Coevolution, Convergent, and Divergent (Adaptive Radiation) Coevolution- change of 2 different species in close association to each other.
