Author | Topic: Beneficial Mutations | |||||||||||||||||||||||||||||||

daaaabear in a nother thread made this statement:
..too bad mutations are never beneficial to any species whatsoever. This thread is an opportunity for him to back that statment up. When his evidence as been supplied (and let's hold it till then please) we can give him evidence of such beneficial mutations.

Heck - I've been drinking, I'll promote the topic.

See, the problem is Nosy that I have no useful scientific credit to actually argue about the science of mutations, from anything i've heard mutations are an extra leg, siamese twins, abnormal growths, and in no way benefit a species.

May I say that is a great response.
Now, before anyone gives you any examples, can I ask you to research using google for one evening looking for examples of beneficial mutaions? Aslan is not a Tame Lion

May I suggest you read through this thread about favorable mutation first before going on?

I do see the theories of beneficial mutation in bacteria but what about larger species? Is there any examples of mammals or more complex organisms that mutate to benefit a generation?
Bacteria and other simple organisms might mutate but it seems like there would be a missing link if one is to look at transitional species between more complex animals.

Spend some more time looking. Start with google +beneficial +mutation and see what you get.
What you learn on your own is far more appreciated than what is handed to you. Aslan is not a Tame Lion

I looked at a good web site but all the evidence was that of adaptations of simple organisms of temperature, growth in dark, genetic divergence, yeast adaptation, improved fitness of random mutations in certain types of bacteria, etc..
Shouldn't there be some modern examples needed of some kind of mutation that would lead to evidence in transitional species?

Look further. Find it on your own.

Mutations produce variation within the individuals of a species. Of course, because all species are in constant change, all species are transitional species.

it it was in english, then i could read it. I'm not a scientist.

it it was in english, then i could read it. I'm not a scientist. 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:
The LPL Ser447-Stop mutation therefore should have a protective effect against the development of atherosclerosis and subsequent CAD. These associations provide evidence for a common mutation that appears to confer beneficial lipid and lipoprotein profiles amongst an adult male population with regard to risk of CAD. This is a rare example of an inherited functional human disorder in which a mutation affecting splicing still permits some correct splicing to occur and this has a beneficial effect to the phenotype of the patients. Gbeta3-s appears to be associated with enhanced immune cell function in humans. Patients with the QQ or H7H7 genotype had a decreased risk of myocardial infarction...
From this site. 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?
