Macroevolution

From Atheist Survival Guide
Jump to: navigation, search

Macroevolution (changes from one species to another) is the observation of larger more visible changes of biological evolution whereas microevolution (changes within a species) is the observation of smaller less obvious increments of change. Macroevolution is disputed by theists who insist that the God of monotheism created all species (kinds) as they are today. Theists cite the fact that only smaller changes (microevolution) have ever been observed in the living. However in order to support the theistic view of evolution (explicitly microevolution), one must abandon the entire fossil record.

While biologists do observe microevolution and macroevolution, the two concepts belong to a single process known simply as "evolution" by natural selection.

Notable scientists in recent history such as Eugenie C. Scott, reject the use of the term macroevolution to describe evolution.

Demonstration

A very good demonstration of the problem of splitting macroevolution from microevolution as two separate processes is presented using the following example:

We all can agree (save for the severely color blind) that this text is red.

We can also similarly agree that this text is blue.

If we have red text and decide to change it by just a small amount, the change might be barely noticeable, but still a very small change. This, we will call micro-evolution. Every word up to now can be considered red, with very minute changes in the hue. If we keep reading long enough, would anyone be able to tell just by looking, at which word or letter is this text no longer red, but actually purple or blue? All this micro-evolution keeps occurring in the text, with its tiny changes in hue, but ultimately, we end up with a completely different color. It's actually the difference between what one would consider red and what one would consider purple (or a whole new species, in this analogy) which is macro-evolution. See, the common misunderstanding is, that macro-evolution means a dog being a direct offspring of some other different canine-like species, or even more stupidly, a cat coming from a dog. Well, that's not what macro-evolution is. There is really only one distinction between micro-evolution and macro-evolution, and it's the same distinction between their prefixes: micro and macro. Just like if something is microscopic or if something is macroscopic. Microscopic usually requires a microscope to see it because it's so small, but the macroscopic are things large enough to be seen by the common human eye. However, things of both size are completely visible and plainly exist, and there are many things in this universe between both general sizes. So as you read this, can you identify the first word here that is blue, and not purple? After all, every change in color since the first word in this paragraph has only micro-evolved from the color next to it, but we've managed to macro-evolve through 2 colors. This, hopefully, will illustrate how it's illogical to believe that macro-evolution doesn't happen, even given time for enough micro-evolution to occur.

So tell me -- what was the first purple word in the block of text above? What's the first blue word? Remember, if macro-evolution simply can not happen then you're saying the words you are reading now are still red.

Survival Tip

In discussions with creationists, macroevolution is bound to be brought up by the creationist in an effort to sound scientific as they reject the idea that evolution transcends species. They will ask to be shown a transitional forms to back macroevolution. Pointing out fossils will not work because the creationist will reject the fossil record as either being a scientific plot to mislead the public, a trick played by God to test our faith, or unable to produce the halfway point between one species and another. Simply point out to them that every living thing is a transitional form and that the proof of macroevolution is everywhere. Let them know that when they are ready to accept the fact of evolution, there will be no shortage of examples for them.

Also, linking to this page for the sake of the demonstration will illustrate how macroevolution and microevolution are simply different ways of observing the same thing.

Remember: always end a discussion or argument by thanking them for their time and by reminding them that it's never too late to learn.
