Re: Brand-Spanking-New Alleles (Again)
That’s right, nothing but false examples of beneficial mutation are repeatedly hyped up by biologists as beneficial mutation!
I'm guessing that any beneficial mutations presented will be arbitrarily assumed false by you but for those with an open mind, one example includes CCR5-delta-32 (a mutation that makes you immune, or nearly immune, to AIDS). Other examples of mutations are those that make our muscles stronger, reduce fat, or provide high cholesterol tolerance. Mutations enabled flavobacterium to digest nylon and apple maggots to digest apples (they used to eat hawthorn). One of my professors has a photographic memory. Some women are reputed to be tetrachromatic (have an extra type of cone photoreceptor in their eyes that allow to see a greater depth of color).
Here's an article by MSNBC that shows pics of a boy that has twice the muscle and half the fat of other toddlers thanks to a genetic mutation. MSN | Outlook, Office, Skype, Bing, Breaking News, and Latest Videos
Everything I mentioned so far is a beneficial mutation. Sickle cell anemia can be beneficial as well, in places where malaria is common.
