Habitat isolationdescribes when two species prefer differenthabitats. Living in different habitats makes it unlikely that these species will encounter each other. For example, in some parts of India both lions andtigersexist. Despite being closely related and capable of mating, lions live in grassland...
Reproductive barriers are an important part of keeping different species separate, despite occupying the same habitat. If two organisms are not able to mate, they will remain separate species. This helps increase the biodiversity of an area or the number of species present. There are two main ...
Mammal, a vertebrate animal whose young are nourished with milk from special mammary glands of the mother.
There are two main categories of endemic species. Paleoendemic species, which are also known as relict species, are ancient species that were once widespread but are now found only in a much smaller area. Causes for paleoendemism includehabitat loss,pollution,climatic changes, the arrival of new...
Among the three types of natural selection, disruptive selection is the least common and can result in the deviation of a species line. This type of selection occurs during periods of change, such as changes in habitat or resource availability. ...

The physical isolation of the population due to the extrinsic barrier is called allopatric speciationThe evolution of new species from one ancestral species living in the same habitat is called sympatric speciation Differentiation mechanism Natural selectionPolyploidy or changes in feeding pattern, etc. ...
Habitat and its Types What is a Biogeochemical Cycle? You live in a biological ecosystem that shows a constant flow of energy between various organisms. There is an exchange of nutrients, which basically translates to exchange of energy. Nutrients ultimately are chemical compounds. So, there is...
or he or it is not. The life ofHelen Kellermakes this clear: when, through the aid of her teacher,Anne Sullivan, Keller was enabled to escape from the isolation to which her blindness and deafness had consigned her and to effect contact with the world of human meanings and values, the ...
By partitioning out resources, species can have long-term coexistence with one another in the same habitat. This allows both species to survive and thrive rather than one species causing the other to goextinct, as in the case of complete competition. The combination of intraspecific and interspeci...
