To all, I think in order to actually explain evolution to
jesus_freak you’ll have to start at around a second grade level and work your way forward.

You see one of my main things is that a mutation is just that...a mutation, and mutations do not prove evolution or anything even close to it
NOTE: I only completed one year of biology in college, I was much more interested in physics so I'm sure others can come up with much better examples. I also vaguely recall that this has actually been observed but I don't know who or when.
Simple example (between each step time/generations pass)
String A - A string of bacteria incapable of eating/processing nylon (This is our definition of String A bacteria)
String A has never encountered nylon and is incapable of processing it.
The string encounters nylon for the first time.
The normal food supply dwindles, but there is an excess of nylon.
A mutation occurs and the bacteria can partially process nylon.
The normal food supply dwindles again, but there is still an excess of nylon.
Q1: Would those bacteria capable of partially processing nylon have an environmental advantage? What would happen to those bacteria without the ability to process nylon? Explain why.
Over the course of generation, those bacteria capable of partially processing nylon gain the ability, through mutation, to better, maybe fully, process nylon.
The normal food supply dwindles, again, to the point of nonexistence, but there is still an excess of nylon.
Q2: Would those bacteria capable of processing nylon have an environmental advantage? What would happen to those bacteria without the ability to process nylon? Explain why.
Over generations, the remaining bacteria start to lose their ability to process the original food supply. (Keeping unused processes active is a waste of energy. The bacteria wouldn’t necessarily lose the DNA coding, it would simply go inactive. Once inactive, the DNA coding may be lost.)
Q3: What would this string of bacteria be called? They no longer meet the criteria for String A bacteria. If they were suddenly moved to a String A friendly environment (no nylon, excess of normal bacteria food) what would happen to this new string?
