Explain the role of mutations in evolution?
Mutations are the material upon which natural selection acts. Evolution is a two sided coin. One side is mutation; the other side is natural selection. Without mutation there is no significant variation. Mutations are, however, ubiquitous. Every organism is a mutant. Evolution can be summarized as the non random survival of randomly varying replicators.
Does medicine have a reverse effect on evolution?
Evolution has no direction. I think you are asking about medicine ameliorating the effects of natural selection as portrayed in this terminology. " Survival of the fittest. " Biologists have never been too comfortable with that term because the ultimate coin evolution pays in is reproductive success, which is a somewhat different thing than just survival. Just because someone is kept alive by modern medicine does not guarantee this persons reproductive success. To launch tour genes into the gene pool is the " goal " of existence and not only do you have to survive long enough to do that your genes must be well represented in the future populations gene pool.

Is there an evolutionary advantage to twins?
The only coin evolution pays in is reproductive success. Having two children who leave no offspring would not give you an advantage over having one child who leaves many offspring. Or any combination thereof. Twinning is a developmental thing of egg doubling or fraternal twins being just like siblings. So, the act of twinning would not seem to confer any more advantage in and of itself, but twins having successful offspring that drive many parental genes to fixation in a population of organism would be reproductively successful that way.

The sociologist who first described society as the survival of the fittest was?
The sociologist who first described society as the survival of the fittest was Herbert Spencer, not Charles Darwin. Spencer applied Darwin's principle of natural selection to human societies, coining the term "survival of the fittest" to explain social change and progress.
Have we humans stunted our evolutionary path by increases in medical science?
No. This is a common misconception that natural selection will not eliminate the " weak " id we medically ameliorate their problems. This misconception is even held by some biologists. Actually, the coin evolution pays in is reproductive success and natural selection can be a creative force to that end. Evolution is the change in allele frequency over time in a population of organisms and the " stunted path " concept implies progress in evolution, but evolution does not care about progress, only reproductive success. If alleles change frequency in populations of organisms, which they do, evolution is not being " stunted, " whatever that means.
From an evolutionary stand point fitness is measured in?
Reproductive success is the coin evolution pays in.
