Evolution is the change of allele frequency in a population of organisms.
So, for a characteristic to affect evolution it must be heritable, genetically so, it must be selected for, or be the result of recombination processes and it must be in the germ line where it is passed to future generation of, hopefully, reproductively successful organisms who leave enough decedents to change the allele frequency in the populations gene pool over time.
It must change the alleles of populations over time. Natural selection, the immediate environmental pressure, can effect not only evolution by adaptive change over time.
That is false.
True. That is the definition of evolution.

sorry, you cannot prove that something is true if it is not true!
It is always true.
True.
To answer this question, you would first have to define evolution. Evolution follows a process of "survival of the fittest." However, this is commonly misconceived as meaning "those who are genetically inadequate die, so their genes don't get passed on." This is close, but not quite how it works. "Survival of the fittest" actually serves to mean "those who survive long enough to breed successfully can pass their genes on." Although these seem ridiculously similar, they are, in fact, extremely different. Genetic adequacy (in a sexual reproductive species) is defined by an organism's responses to stimuli from organisms within the same species of the opposite sex. This is seen most commonly as "attractiveness." When you see someone you find "attractive," your brain is computing a response to the various stimuli from your sensory organs and telling you that that your body thinks that the genes that person has would improve your own in your offspring. The combination of those genes is what constitutes the process of evolution, as it averages the genes in question based on their dominance, and a certain level of random chance. My point in this explanation is that if a specific organism is seen as "genetically inadequate," it may not die because of that genetic inadequacy, but it also might not be able to find a mate that will accept them, regardless of that inadequacy, and thus their genes are still not passed to a subsequent generation. Another factor that affects an organisms ability to pass its genes on is sterility. A sterile organism is an organism whose reproductive organs are physically incapable of functioning. This can be caused by birth defects, or post-birth damage to said reproductive organs, and/or their complementary systems. All in all, a characteristic that would affect evolution is any characteristic that would stimulate or prevent an organism from passing on its genes to subsequent generations. For a characteristic to affect evolution it must be inheritable. That it is heritable, that is it is in the generic germ line and is passed successfully into the population's gene pool.
A good hypothesis should be clearly defined with no ambiguous terms. It should also have a strong possibility at being correct.
