Adaptive radiation occurs when a population colonize a new environment that has a variety of different habits and FEIL competito

CaHeK987 [17]

Answer:

True (although question is not clear enough)

Explanation:

Adaptive radiation occurs when organisms evolve from the same ancestor. This process takes place as a result of environmental changes or when they are introduced to or colonize a new environment. These changes become challenges that force these individuals to adapt to these new conditions.

Therefore, this results into a faster evolution that creates different new forms that possess a diversity of variations adapted to their new feeding habits, environment, and behavioral needs.

One of the most famous examples of adaptive radiation is the formation of new forms of Galapagos finches. These striking finches, which arose from a common ancestor, evolved different beak sizes and shapes that were especially adapted to different types of food. As different as they may appear, they are closely related!

After Darwin proposed his ideas about natural selection as a mechanism for evolution, it took time before evolution was generall

OverLord2011 [107]

Answer:

A scientific theory refers to the possible explanation of the natural event. It can be tested repeatedly and can be verified by anyone with the help of predefined sets of protocols and scientific experimentation.

Similarly, Darwin proposed the idea of natural selection as the mechanism of evolution.

Various experiments in labs, as well as observations made under natural conditions, proved that natural selection plays a major role in the evolution.

Examples may include industrial melanism of peppered moths, long neck of Giraffe, different shapes and sizes of beaks of Darwin finches et cetera.

This is why natural selection is considered a theory now.
