Hi Christopher,

Your "short" list of questions concerning evolution will very difficult to
deal with in this format.  Some of the questions are fairly clear, but most
seem a bit vague or open-ended.   Perhaps you should first read sections of
a good general biology text.  I also recommend the writings of Richard
Dawkins for clarity and Stephen Jay Gould for fun.  Regardless I shall try.

Evolution describes the changes in the diversity of life over time.
Evolutionary theory describes the processes thought responsible for those
changes.

 Organisms must pass their traits to subsequent generations. See
evolutionary theory.

Directed evolution does not exist in the natural world, it is an oxymoron.
Molecular biologists can engineer genes but that is not even close to an
evolutionary process.  Think of those new genes as mutations or
recombinations of old information into something different.  See subsequent
generations.

Adaptations that are heritable may increase in subsequent generations.  See
something different.
