What Evolution is NOT

Evolution is NOT a fact.. It is a theory: a highly probable explanation affecting all biological phenomena, with much supporting evidence, and NO evidence against it.

It is NOT concerned with the origin of life… Only the origin of species.

It is NOT just concerned with the origin of humans…. No more or less than any other species.

It was NOT first explained by Charles Darwin… Many other people proposed the general idea long before Darwin did.

It is NOT the same as natural selection… Natural selection deals with how evolution can take place; this idea was first proposed by Charles Darwin.

It is NOT something which happened only in the past… It is still going on today…

It is NOT something which happens to individuals… Evolution happens to populations.

It is NOT an accidental or random process… There are built in limits and constraints; it is influenced by both historical circumstances and environmental factors.

If this is what evolution is NOT….then what is evolution?

Evolution is… Gradual change in a species through adaptations over time.

Hypothesis v. Theory H - Explanation for a question or a problem that can be formally tested. T – explanation of natural phenomenon supported by a large body of scientific evidence obtained from many different investigations and observations.
