Many RWNJ creationists don’t understand the concept of natural selection. So, here are some simple steps to explain the concept using the example of green and brown beetles:
1. Variation In Traits
Check out this example. There is a variation of traits with these beetles. Some of them are green and some are brown.
2. Differential Reproduction
The environment can’t support unlimited population growth. The green beetles get eaten more, so they don’t survive as much.
The brown beetles survive, and their babies are brown because the trait has a genetic basis.
4. End Result
Eventually, all of the beetles become brown because the green ones get eaten.
Here are some of the common misconceptions surrounding the theory of evolution:
1. Humans Evolved From Monkeys.
This is the most common misconception. From the University of Wisconsin – Green Bay website:
“Humans and great apes had a common ancestor about 5 million years ago Humans and monkeys had a common ancestor about 50 million years ago. Nowhere, except in the most illiterate anti-evolution literature, will you find a claim that humans evolved from monkeys.”
2. It’s Only A Theory
In the case of science, a theory doesn’t mean a “guess.” A theory is an organized set of ideas. A hypothesis is a theory that hasn’t been confirmed. So, evolution has been confirmed by science.
