what is speciaton???explain its factors with appropriate examples?
Answers
Answer:
What are the factors of speciation? ... Factors that lead to speciation include genetic drift, natural selection, geographical isolation, mutation. Geographical isolation is not a major factor in the speciation of a self-pollinating plant species as pollination occurs between the reproductive organs of the same flower.
factors
- geographical isolation.
- natural selecting.
- genetic driff.
Answer:
1)An example of speciation is the Galápagos finch. Different species of these birds live on different islands in the Galápagos archipelago, located in the Pacific Ocean off South America.
2)The finches are isolated from one another by the ocean.Speciation is the evolutionary process by which populations evolve to become distinct species. The biologist Orator F. Cook coined the term in 1906 for cladogenesis, the splitting of lineages, as opposed to anagenesis, phyletic evolution within lineages.Species and Speciation
3)The best-known example of incipient parapatric speciation occurs in populations of the grass Agrostis tenuis which span mine tailings and normal soils. Individuals that are tolerant to heavy metals, a heritable trait, survive well on contaminated soil, but poorly on non-contaminated soil.
4)Explanation: Speciation occurs when two or more populations become so genetically distinct that they no longer interbreed with one another. ... Allopatric speciation is when populations become separated geographically and diverge over time due to natural selection, mutations, and genetic drift within each populationExamples of Allopatric Speciation
5)Darwin's Finches. A major example of allopatric speciation occurred in the Galapagos finches that Charles Darwin studied. ...
Grand Canyon Squirrels. ...
Peripatric Speciation. ...
Parapatric Speciation. ...
Sympatric Speciation
6).For example: Allopatric speciation occurs when an animal population is forced to be split between two geographical areas as a result of geographical change. As a result, there are mutations that occur in the split populations which affect the ability of the two groups to reproduce if and when they are reintroduced.
i hope it helpfull to you
