Question

what is speciation? explain with the help of an example..

Answer 1

Speciation is how a new kind of plant or animal species is created. Speciation occurs when a group within a species separates from other members of its species and develops its own unique characteristics.

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. The finches are isolated from one another by the ocean. Over millions of years, each species of finch developed a unique beak that is especially adapted to the kinds of food it eats. Some finches have large, blunt beaks that can crack the hard shells of nuts and seeds. Other finches have long, thin beaks that can probe into cactus flowers without the bird being poked by the cactus spines. Still other finches have medium-size beaks that can catch and grasp insects. Because they are isolated, the birds don’t breed with one another and have therefore developed into unique species with unique characteristics. This is called allopatric speciation.

Answer 2

Hey mate !!

Here is your answer........

Speciation means the formation of new and distinct species in the course of evolution.

Hindi meaning -: पृजातीकरण

Example.........

* Allopatric speciation occurs when an animal population is forced to be spilt between two geographical areas as a result of geographical change . As a result , there are mutations that occur in the spilt populations which affect the ability of the two groups to reproduce if and when they are reintroduced.

The above was a type of speciation.

Here are a few examples of that ......

1- Hawthorn fly

2- Three - spined sticklebacks

3- Cichlid fishes in Lake Nagubago

4- Tennessee cave salamanders

5- Greenish Warbler

6- Ensatina salamanders

7- Larus gulls

8- Patroica multicolor

9- Drosophila

10- Mayr bird fauna

11- Finches

12- Squirrels in the north and south rims of the Grand Canyon

13- Apple maggot

14- Faeroe island house mouse

15- Primula kewensis

16- Croatian lizards

Speciation can be natural and can occur as a normal part of the evolutionary process. Artificial speciation is also possible and can be created by laboratory experiments or through agriculture and animal husbandry. Fruit flies are primary example of artificial speciation. Another well - known example is domestic sheep.
