Some people argue that evolution, which is generally associated with progressive increases in the
yKpoI14uk [10]

This argument would not be valid because it fails to take into account the <u>mechanisms </u><u>through which </u><u>evolution </u><u>occurs</u> and misunderstands the <u>second law </u><u>of </u><u>thermodynamics</u><u>.</u>

The second law of thermodynamics states that the total entropy of a system must always increase. The argument stating that this law disproves evolution given that evolution can be considered as a <u>decrease in entropy</u>, fails to realize that the <em><u>second law</u></em> states that the <u>total entropy </u>must increase, this does not mean that entropy cannot decrease at one point, to then increase more so at another.

The other aspect of evolution that this argument fails to account for is that evolution is a chaotic process. Evolution, though having a final product that may be considered as increasing in organization, is at heart <u>a </u><u>chaotic process </u><u>caused by</u><u> random mutations</u><u> and the fragile process of </u><u>natural selection</u><u>.</u> Therefore, rather than disprove it, the<em><u> second law of thermodynamics</u></em> is actually the driving force behind continued evolution.
