Evolution: Evolution is the process by which populations of living organisms change over generations. It is driven by natural selection, which is the process by which organisms with traits that are better suited to their environment are more likely to survive and reproduce. Over time, this can lead to the emergence of new species. See also Selection, Mutation, Species, Survival, Fitness, Darwinism._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

Marvin Minsky on Evolution - Dictionary of Arguments
I 145 Evolution/Minsky: Evolution illustrates how processes can become enslaved by the investment principle. >Terminology/Minsky. Why do so many animals contain their brains inside their heads — as with fish, amphibians, reptiles, birds, and bats? This arrangement was inherited long before our earliest aquatic ancestor first crawled upon the land three hundred million years ago. For many of those animals — woodpeckers, for example — another arrangement might serve at least as well. But once the pattern of centralizing so many functions in the head was established, it carried with it great networks of dependencies involving many aspects of anatomy. Because of this, any mutation that changed any part of that arrangement would disrupt many other parts and lead to dreadful handicaps, at least in the short run of evolution. And because evolution is so inherently short-sighted, it would not help if, over longer spans of time, such changes could lead to advantages. >Obsolescence/Minsky._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
