Beneficial Mutations

If you do as jar suggests, and put "beneficial mutations" into Google, the very first hit is "Examples of Beneficial Mutations in Humans".(Unless maybe you consider humans to be "simple organisms"...)

Perhaps, but these are real sources, and not propaganda from a website pushing one view or another.The initial jargon-shock doesn't mean you should throw your hands up - try scanning it, since they put the lay conclusions in bold: From reading these, can you at least glean that beneficial mutations have been found in humans, that reduce heart disease and improve immune system function?Though not on that site, mutations have also been found in humans that make them resistant to infectious disease (HIV, malaria), and better able to function in high-altitude, low-oxygen environments - and likely others as well.Are you convinced yet?

Never? How open-minded of you.Actually, though, I meant, "are you convinced that beneficial mutations occur?" - I'm still wondering what you think on that point. It doesn't, though I would say that a gene spreading through the human population that prevents HIV infection, or prevents heart disease despite a poor diet and smoking, is quite "advanced".You are not going to find a single scientific paper that "proves" evolution. Each study presents its findings, nothing more. If it presented more, it would likely cease to be science. Every organism, including you, is a "transitional" between its/your parents and its/your children. If that wasn't the case, you would be identical to your parents and children. You seem to be mixing up concepts a bit. You were asking about "beneficial mutations", which I gave you examples of in humans. Now you've switched the issue to "speciation", that is, one species becoming two species. It is rare that a single mutation will result in a speciation event (for example, a mutation that alters reproductive behavior). Speciation is generally much more gradual, the result of accumulation of many genetic differences, often in geographically isolated groups.Make sure you keep the two concepts "beneficial mutation" and "speciation" separate, since beneficial mutations are not necessarily required for speciation as you suggest in the above statement. Neutral genetic mutation can also result in speciation by producing reproductive compatibilities within a group, splitting it into two.Perhaps reading over the thread How do we define a new species? will be helpful.

hey daaaaaBEAR,Hopefully you realize that this six-word non-response is downright rude, considering I put effort into a page-long response trying to inform you. Perhaps you care to respond to anything else in my post? Is there something you would like explained differently?Specifically, do you now believe that beneficial mutations occur? That is the subject of the thread, and you have been given evidence.What do you think? Do beneficial mutations occur?
