Supposing for a moment that we could trace the origins of all to one organism (which we have not), what would the impetus for variety possibly have been?
"Limited attacks on a system" refers to that which will strengthen a system without destroying it. Strength only builds when rest/recuperation is allowed. What thinking part of NS determines the thre ...[text shortened]... t species, evolution's biggest gap remains insurrmountable--- that is, not counting miracles.
Apart from that, there are so many problems with what you just said. How is "rest/recuperation" relevant to natural selection?Why does strength depend on it? In fact, to make it easier forget the term natural selection. What we describe as natural selection is just the emergence of variations that have more chance of passing on their genes to their progeny.
As for the species turning into another species, I would argue that the definition of a specie is vague. I will just assume you mean an accumulation of variations i.e. that would make one ancestor largely distinguishable from its descendents. There is, of course, no reason to think that this cannot happen. If we observe one mutation, we can infer that millions of mutations can also occur over a larger period of time, thus giving a new "species".
I will maintain that the theory of evolution is not inductively based but deductively based. We do not need to observe it. However, we do examine fossils which substantiate the theory.
