Your Views: Natural selection is a survival mechanism for all organisms

POSTED: February 22, 2014 1:00 a.m.

Evolution is a fact. But let’s call it by its proper name, natural selection. Natural selection is not a “law;” it is a process where populations (including human) physically change over time to meet the challenges of an ever changing environment.

Sometimes these physical or physiological changes are great, sometimes small. We humans are undergoing imperceptible physical changes in every succeeding generation.

Here is an example: In the general human population there is a small but growing group of individuals who are born without a third set of molars (commonly called wisdom teeth). At some point in the future, “wisdom teeth” will become very rare, then disappear completely from the population. This process could take thousands of years with no one taking notice (except dentists) but, this is natural selection in action.

I recommend George Kaulbach read “The Origin of Species” by Charles Darwin, the original version. In the original version the word “evolution” is not used. In the first section of his book, he details how mankind used natural selection for thousands of years to improve domesticated plants and animals. Selective breeding is just mankind’s manipulation of natural selection.

The rest of the book details physicals changes in animal populations and how they adopt to specific environmental challenges. What Darwin is saying is that man has harnessed a natural process called natural selection.

This process is what everyone commonly refers to as evolution. It is the survival mechanism of all organisms: Adapt to the environment through natural change or go extinct. The more a marginal population changes from the main population the more likely it will become a new species.

This is a fact of life.
