the textbooks are a lie, so you are going off false information. Mutations are just what they sound like. Mutations! These are things that may or may not be passed on genetically, and even if they are...how is that an improvement? How did man progress from apes with cancer?

Your logic is flawed and ill-informed.
Mutations can either increase the chance of survival or decrease the chance of survival (or of course have no effect), on an individual level. Obviously, those mutations would decrease the chance of survival and be selected against - meaning the holder of those traits would often times die before being able to reproduce and pass on those traits, in nature.
Your view of evolution isn't quite whole. Evolution means both success and failure - in nature, the failures are natually selected against, making the line stronger.
In application with humans, of course these 'mutations' are not selected out and the holders of such mutation can go on to reproduce - this is how we as an 'advanced' society fight evolution without knowing it.

No.
Darwinian theory provides for "Survival of the Fittest"
Read that carefully. "... of the FITTEST"
Genetic anomalies that cause people to die - according to Darwinian theory - are nature's way of wiping out the weak. ie-bad genes. Those genetic anomolies cannot survive in the current environment OR it's the environment that triggers the anomalies.
for instance... diabetes... practically unheard of 25 years ago.
Sugar and processed foods - not a big part of the american diet 25 years ago. You overload on sugar 24-7, your body gets pi**ed and stops making insulin or makes too much. Not because of 'evolution or genetics' but because the ENVIRONMENT changed.

yes, as said before evolution was said by Darwin to be survival of the fittest, but that just means that those less fit didn't survive to pass on they're genetic material.
Oh and by the way badandigood, I have diabetes and I happen to know that there are 2 types of diabetes and you got them mixed up, Type I, which is caused by the body's immune system or a foreign agent destroying the islets of Langerhans which are the glands that make insulin, sugar intake has absolutely no affect at causing it, Type 2 is the production of either insufficient or deformed insulin and can be caused by food intake or weight, GET YOUR FACTS STRAIGHT!

Even though scientists say creatures evolved things like wings, legs, eyes, ears, lungs etc, through mutations, we should be able to see that as false since there are hardly any records of beneficial mutations in the modern world.
