Flaws of Evolution: Part One

As some of you may not realize there are many flaws in the way evolution is made up. One of which is:

This is part one of my telling (some of) the flaws of evolution.

  1. Evolution is not about always increasing the number of different traits, it’s about selection of the best traits over time. In each specific case, this could mean that the traits are getting simpler or more complicated depending on which one is favored.

    What you are looking at here is a very specific selection for a particular trait (long necks). One trait is preferred over the other because of its ability to aid survival. Over time, the “weaker” trait dies out and the “stronger” trait is passed on. Evolution is occurring here as the giraffes in the succeeding generations are better suited for survival in their environment. This is the essence of evolution….not the idea to collect as many different variations of the same trait as possible.

    • First of all, sorry it took so long to approve the post, somehow it ended up in spam.

      With that said, one thing I’d like to point out is that the ‘long neck trait’ isn’t stronger, it is merely more useful for surviving in the giraffes current circumstances. If, for some reason, all the trees started to grow very short, the giraffes with short necks would survive better. But they all have died already, so there are no more ‘short-neck’ genes. What would happen then?

      • I should clarify that by “dying out”, it does not necessarily mean that it has to die out completely. Though that scenario is possible as well, a lot of the times it’s just the allele frequency that decreases. Also, it’s important to realize that for many traits, it’s not simple matter of tall vs short, or big vs small. It usually occurs on a scale, so when one end of the scale is favored, the population’s average slowly shifts towards that end of the scale. In your specific case, if the environment changed so that long necks is no longer suitable, the neck sizes well slowly decrease.

        There is actually a classic example of this scenario that’s given in almost all high school biology books:http://en.wikipedia.org/wiki/Peppered_moth_evolution

        Essentially, the industrial revolution caused a dramatic change in the environment and the moths trait frequency adapted appropriately.

        A more recent example is the evolution of the beak size of Darwin’s finches in the Galapagos, the short article is here (http://www.livescience.com/4147-darwin-finches-evolve-scientists-eyes.html) but I be happy to send you the Science paper if necessary.

        There’s even more examples of this allele frequency change in microbiology, since bacteria reproduce and mutate at a much faster rate than animals.

      • That’s ridiculous! A moth changing colors is not evolution. It is merely adapting to its environment. And as it says, Peppered Moths have started to become light again. There is no genetic advancement there.
        And about Darwin’s finches, a smaller beak does not make a new animal. I suppose different circumstances could cause the finches’ beaks to become larger again. And I also suppose it’s possible for them to start growing crests, or for the color of their feathers to become lighter; either way, they stay the exact same bird.
