Evolution

The process by which plants and animal forms develop by decent with modification from earlier forms.

 

There are those who vehemently oppose the very idea of evolution, refusing to acknowledge it is scientific fact.

 

Often assertions are made in the vein that complicated things such as human brains and behaviour, etc., in all seriousness simply cannot credibly be the result of chance, therefore, the idea that we are the product of Evolution is ludicrous!, referring to it as only a theory. For example, opponents of Evolution like to talk about the (extremely) low odds of a chimpanzee composing some famous piece of music to illustrate this point, that, in their minds, in Evolutionary thinking complex things are postulated to have come together purely by accident.

 

1.

Mutations (copying mistakes), a major ‘driver’ of Evolution, are random and occur irrespective of whether they would be useful to or adaptive for the individual organism, happening haphazardly and involving accidental changes in the DNA sequence of the organism;

2.

However, the process of Evolution by Natural Selection is the polar opposite of being random: adaptive changes are probabilistically retained. The genes of those organisms which survive and successfully reproduce are passed on to subsequent generations: in short what works is preserved.

Evolution by Natural Selection is an unguided process.

 

Actors holding such views may complain that Evolution has little value at all, for example, preferring what they may see as the safe and comforting notions of Biblical Creationism and Intelligent Design (ID): a religious story and a dogma rather than scientific claims.
