<u>Answer:</u>
<em>Darwin was a British naturalist UN agency planned the idea of biological evolution by survival of the fittest.
</em>
In <em>living organisms, several characteristics are transmissible, or passed from parent to offspring</em>.
(Darwin knew this was the case, even supposing he didn't understand that traits were transmissible via genes.)
Organisms are capable of manufacturing a lot of offspring than their environments will support.
<em>Thus, there's competition for restricted resources in every generation.
</em>
The offspring in any generation are slightly totally different from each other in their traits<em> (colour, size, shape, etc.), and lots of of those options are genetic.
</em>
<em>To make survival of the fittest a lot of concrete, let's take into account a simplified, theoretic example.</em>
During this example, <em>a gaggle of mice with genetic variation in fur colour (black vs tan) has simply touched into a brand new space wherever the rocks are black.
</em>
<em>This surroundings options hawks, that prefer to eat mice and may see the tan ones a lot of simply than the black ones against the black rock.
</em>
Because the hawks will see and catch the tan mice a lot of simply, a comparatively giant fraction of the tan mice are consumed, whereas a way smaller fraction of
<em>If we glance at the quantitative relation of black mice to tan mice within the living ("not-eaten") cluster, it'll be more than within the beginning population
</em>
