Quote Coragyps: I've got news for you - in parts of Africa where malaria is endemic the increased resistance to malaria outweighs the downside of the mutation, so guess what?
It's a positive mutation after all in the right environment.

Right environment huh? That is evolution's greatest weakness you know. It is mathematically impossible for all the circumstances to happen right.
Actually it was me, not Coragyps who said that.
Well yes of course in the right environment.
The environment can be a major selection factor. As an imaginary example suppose there is a population of some animal living on an island. There are two different mutations existing in the population, one of which causes the animal to have thicker, warmer fur while the other causes the animal to have thinner, cooler fur. Initially the island has mild winters so neither mutation is selected for. The climate then changes so that the winters become much harsher and colder. The animals with the thin fur mutation will be strongly selected against (i.e. more of them will die in winter), those with neither mutation will also be selected against (but not as strongly) while those with the thick fur mutation will be selected for. The long term result of this selection pressure
from the environment will be that the thick fur mutation will become universal through the population.

Well I'm sure you'll have no trouble showing us the maths to demonstrate this then (in accordance with rule 4 in the Forum Guidelines).
Edit: I see while I was typing this you put in some AIG links purporting to 'do' the probability. I dare say others will refute them while I'm offline (which I will be in a few minutes until late today or tomorrow). Suffice to say for now they're about the quality you'd expect from AIG.
In order to support evolution these mutations need to add information to genes.
Groan....
There are seemingly endless threads on this subject on this site. If you can substantiate your assertion you should post in one of them. All you will need to do is provide a meaningful definition of information and describe how we can measure it so we can tell if it has been added or removed.
You're the latest in a long line of creationists spouting this drivel - not one of them to date has been able to back up what they say.
