Re: On Evolution
In Response To: Mitochondrial Eve ()

Let us leave the other subject to be determined by others and not necessarily your or my friends.
This is a collection of notes on Evolution. It is for consideration and not necessarily to convince you of anything.

Biological evolution is a change in the genetic characteristics of a population over time. That this happens is a fact. Biological evolution also refers to the common descent of living organisms from shared ancestors. The evidence for historical evolution -- genetic, fossil, anatomical, etc. -- is so overwhelming that it is also considered a fact. The theory of evolution describes the mechanisms that cause evolution. So evolution is both a fact and a theory.

When most people talk about biological evolution they often confuse two different aspects of the definition. On the one hand there is the question of whether or not modern organisms have evolved from older ancestral organisms or whether modern species are continuing to change over time. On the other hand there are questions about the mechanism of the observed changes... how did evolution occur? Biologists consider the existence of biological evolution to be a fact. It can be demonstrated today and the historical evidence for its occurrence in the past is overwhelming.

Evolution is a theory. It is also a fact. And facts and theories are different things. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts don't go away when rival theories are debated to explain them.

Evolution as a process that has always gone on in the history of the earth can be doubted only by those who are ignorant of the evidence or are resistant to evidence, owing to emotional blocks or to plain bigotry.

"Nothing in Biology Makes Sense Except in the Light of Evolution" - Theodosius Dobzhansky

The controversies about evolution lie in the realm of the relative importance of various forces in molding evolution.

Since Darwin's time, massive additional evidence has accumulated supporting the fact of evolution - that all living organisms present on earth today have arisen from earlier forms in the course of earth's long history. Indeed, all of modern biology is an affirmation of this relatedness of the many species of living things and of their gradual divergence from one another over the course of time. Since the publication of The Origin of Species, the important question, scientifically speaking, about evolution has not been whether it has taken place. That is no longer an issue among the vast majority of modern biologists. Today, the central and still fascinating questions for biologists concern the mechanisms by which evolution occurs.
