Paragraph 1: I agree. That is quite right.

Paragraph 2: Adaptation is not that simple. Sometimes it is reversible. For example, take epigenetics. Epigenetic changes to a creature’s genome only turn on or off certain parts of the genome. It lasts several generations, but can change back. There is, of course, a type of adaptation where a creature actually loses bad genes, but is this really evolution? A creature can’t evolve into something better if all that happens is it loses little bits of its DNA over millions of years. For actual macroevolution, there needs to be new information added, and that new information has to benefit the creature. Like I said, we’ve selectively bred dogs for thousands of years - they are still dogs, they just express features already in the genome of their ancestors. No macroevolution has occurred.
