TED-Ed: Myths and misconceptions about evolution

How does evolution really work? Actually, not how some of our common evolutionary metaphors would have us believe. For instance, it’s species, not individual organisms, that adapt to produce evolution, and genes don’t “want” to be passed on — a gene can’t want anything at all!

    Interesting, do you care to elaborate on your thoughts about species vs individual organisms and how/why a gene can’t want anything at all?

    • This isn’t my video and your questions are both vague and confusing, so I don’t really want to put the time into giving you a detailed answer. Sorry.

        To clarify, while you did not make this video you found it interesting. I take it you wrote a few comments about the parts you found most interesting: the misconceptions about species vs individual organisms and the fact that a gene can’t want anything. I was asking you if you would elaborate more on why you found these two points from the video interesting?

        But alas, if you do not have the time I will understand.

      • That text was copied from the description under the YouTube video and TED-Ed site.

        If you watch the video it directly addresses these points. The example given is that a giraffe doesn’t somehow generate the gene for a long next by stretching for food over its lifetime (individual organisms). Instead, some giraffes were born that just happened to have longer necks and those were more successful in their environments, so passed on their traits.

        The idea that a gene cant ‘want anything’ seems self-evident to me. I wouldn’t know how to argue that a molecules could want anything. The video goes on to explain that evolutionary changes aren’t a part of some plan. Our genes aren’t working to become more ‘perfect’ in any meaningful way. They’re simply mutating, sometimes with positive effects on our survival, sometimes not.

        I think the video explains this pretty well, which is why I shared it here.
