Not quite so simple...

Evolution is simple to understand.
First of all, there is element called Variation. Variation is illustrated in the differences between any 2 people. For example, one might have a longer nose, or might be taller, etc.. Even siblings have such variations.
Your description of evolution is not correct. You have not identified an important source of variation, namely mutation.
Another indication that your description is wrong is that it cannot account for mutations in organisms such as bacteria and viruses that do not reproduce sexually.
Edited by NoNukes, : fix punctuation

I will disagree with your estimate. Inherent in variation is mutation and in viral evolution we witness the overall changing of the virus in response to changes in the virus' environment, incorporating variation
Your statement is not clear, but I assume that you are not advocating a Lamarkian explanation of evolution.
Your original post never mentioned any source of variation other than combining traits from diverse parents and your explanations and examples do not indicate any effect due to mutation. Mutation can allow offspring to have traits that were not present in the previous generation or in either parent.
In other words, you might only start off with 1 viral organism within a host which can fight an antibiotic
Antibiotics do not work on viral organisms. I assume that you meant to refer to a bacterial organism. With that correction, I agree with you.
But you might also start out with no bacterial organisms that can digest nylon and eventually create a colony of bacteria that does have that ability.
