Yes. The basic definition of evolution depends on changes in the frequency of alleles in a population.
Evolution is when a species develops and diversifies at the genetic level to better fit it's environment . Evolution is natural , and occurs so species can survive . Scientifically speaking , when the earth was created , there were only single-cell bacteria around . If they hadn't evolved , they probably wouldn't have survived the ice age , etc .
Yes, physical adaptions are genetic, it's called evolution.
Genetic evolution refers to the variations in inherited traits of biological populations over successive generations. It is also referred to as the selfish gene theory.
Evolution is the change in allele frequency over time in a population of organisms.
contributes to genetic variation.
All evolution that results in increasing genetic divergence between subpopulations may result in speciation. That includes convergent evolution: convergence occurs at the phenotypical level, not at the genetic level.
All reproductively isolated populations diverge genetically. Even in cases where convergent evolution occurs, this is only at the behavioural and morphological level. At the molecular and the genetic level, even these instances still diverge at the genetic level.
Evolution is not a cause of genetic change: it is the effect of genetic change.
Genetic mutation does not always lead to sterilization as you point out. This however is not the way evolution happens. Evolution occurs mainly through small adaptive changes over a long period of time that are not mutations. Evolution does not happen suddenly.

Organic evolution.
Genetic evolution refers to the variations in inherited traits of biological populations over successive generations. It is also referred to as the selfish gene theory.
Micro-evolution is not only a part of macro-evolution, it is the same mechanism as macro-evolution. Macro-evolution includes speciation, as a result of continuing micro-evolution.
