Doesn't Evolution Violate the 2nd Law of Thermodynamics?
The second law states that "In a closed system (one in which energy cannot enter), Entropy will not decrease." Since Entropy often refers to disorder, this law is often taken to mean that order cannot arise from disorder. How then would life, which is highly ordered, form naturally? The answer, simply, is that life is not a closed system. Energy is constantly being added to the Earth from the Sun, which fuels the plants, which in turn fuel other life. This is how plants, for example, can have more energy than the seeds they originally sprouted from. But life is not the only example of order from disorder. Snowflakes, crystals, lightning, and sand dunes are all examples of non-living matter organizing into complex structures.
