Beneficial Mutations

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.

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.

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?

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

no, sorry. If by convinced you mean converted to evolution then never, but at the time I don't see how this article makes it possible for mutation that is more advanced than improvment against disease and immune systems, etc..Crashfrog says that every species is in a state of transition. If humans are are in transition then how does resistance to disease make us mutate into a different species?That article gives no examples of beneficial mutation that would lend to whole new species.

I only leave room for truth.
