Anything worth talking about, is worth blogging about

Creationists and cdesign proponentists often argue that microevolution (changes within a species) occurs, while macroevolution (gradual change from one species to another) does not. Of course, those types are merely in denial of reality, as they are never able to explain what’s going on with this mythical species barrier” they keep positing.

The reason for this is, of course, the fact that macroevolution and microevolution are the same thing. This picture (via) stunningly illustrates the fallacy of the “species barrier”.

An illustrated paragraph of text showing a gradual change from red to blue text, showing that macroevolution is merely microevolution on a large scale

  1. You still have text at the end. Change in color is micro-evolution, not macro. Good try, but still a failure.

  2. What you’re doing is arbitrarily declaring colour change to be microevolution merely by definitional fiat. It is entirely possible to make a more extensive example, by like gradually changing the text into a picture, but using only colour change reduces the traits varied to one, therefore making it easy to understand. The point is that a large number of small differences in degree can “add up” and eventually result in a difference in kind.

  3. If you start with text and it gradually becomes a living breathing dog, then you have macro-evolution.

    Slight changes to the pixels on a screen, where they remain pixels, is just micro-evolution.

    Nothing arbitrary about this standard. This is common sense basics.

  4. Give up on reaching the religious, Rob. They don’t WANT to understand. They just want to continue convincing themselves they don’t already know they’re wrong.

  5. Nice post, I may have to steal it for one of my Sunday disservices in the future. 🙂

  6. @The Ceej: They are claiming that a lot of traits changing simultaneously, which is “macroevolution” and supposedly can’t happen, whereas a single trait changing is “microevolution” and can happen, even though we can use “microevolution” to get the same result as “macroevolution” simply by selecting one trait, gradually changing it until that trait is the same as in the macroevolved entity, and repeating the process mutatis mutandis with the other traits. In other words, it’s drawing a distinction between a process that reaches an end by changing multiple traits simultaneously, and reaching the same end by changing the traits one after the other. In other words, a meaningless distinction, as “macroevolution” is merely “microevolution” on a large scale.

    But then again, this would perhaps be expected from someone who I gave a list of observed instances of speciation over a year ago, and who promised to get back to me but didn’t.

  7. @The Arbourist: You are welcome to do that.

  8. It’s what they do. They shift the goalposts and do anything they can to hold onto their little delusion because they can’t handle the possibility they might be wrong.

    I’ve done the same sort of transition, unintentionally. I have an opening sequence to a work that starts out a Back To The Future parody and ends up a Dick Van Dyke Show parody. At no point through this transition can you tell when the BTTF parody ends or when the DVDS parody begins. It’s a smooth gradual transition.

    Of course, no argument will work for those who hold steadfast onto their beliefs and refuse to allow information to come in. They’re lost causes. As long as they’re not bothering the rest of us (which is a group you SHOULD focus on), let them have their little delusions.
