Random fluctuations can also cause changes, ... As was noted in the introductory paragraph above, natural selection is one of several different mechanisms that cause evolutionary change in populations. Natural selection operates to produce individuals that are better adapted to their environment.

In an attempt to better understand the operation of the Darwinian principle involved, this particular article analyzes a small segment of our society - the automobile manufacturing industry - and considers whether Darwin's great engine of "Natural Selection" operates to produce an understanding of the "evolution" ,

Natural selection operates to produce individuals that are better adapted to their environment. ... Natural selection is the process of differential survival and reproduction that inevitably leads to changes in allele frequencies over time as those individuals who are the most "fit" survive and leave more offspring.

Variation is the raw material upon which natural selection operates. Reproduction leads to ... Every organism is adapted for how and where it lives, However periodic changes in resource availability allow subsets of these populations, ...

Moreover, because the mechanism of natural selection operates by eliminating the less fit, it must eventually lead to less diversity ... Processes that produce changes in the genes occur by chance through mutation and only once the gene has been transcribed and produced the phenotype can natural selection come into play.

This genetic variability (that arises by chance) is what natural selection operates on to the produce the genetic changes in a population which (with time) leads to evolution.
