These are areas and/or ways of life that can be exploited by different types of animals.
For example, in a rainforest, there are niches for animals that can climb to access fruit, but there are also niches for animals that will eat fruit that has fallen to the forest floor.

Evolution and Diversity Evolution and Diversity The foundation for the theory of evolution was laid by Charles Darwin (Rose, n.d.).
In this process, species gradually change in various ways.
The changes that are useful will be passed on to future generations and may eventually lead to the rise of new species.Educators go through a rigorous application process, and every answer they submit is reviewed by our in-house editorial team.In any ecosystem, there is a wide variety of ecological niches.He developed hypotheses about natural selection which helped scientists develop the theory.Evolution is a theory and not a hypothesis because evolution has been proven by vast amounts of scientific data, research, and testing.It is hard to truly estimate what fraction of offspring will survive to reproduction.There are always obstacles to survival for an organism.The diversity of living forms and the unity of evolutionary processes are themes that have permeated the research and writing of Ernst Mayr, a Grand Master of evolutionary biology.The essays collected here are among his most valuable and durable: contributions that form the basis for much of the contemporary understanding of evolutionary biology.The most significant and rapid genetic reorganization occurs in extremely small populations that have been isolated (as on islands).His theory of peripatric speciation (a more precise form of allopatric speciation which he advanced), based on his work on birds, is still considered a leading mode of speciation, and was the theoretical underpinning for the theory of punctuated equilibrium, proposed by Niles Eldredge and Stephen Jay Gould.
