Why be good?

Jenny-

If you Google the terms "theory of evolution' and "natural selection", you can read about the "survival of the fittest".

If she wants to read about survival of the fittest, her best bet would be to google that phrase, not the other two. So that is exactly what I did -- I googled survival of the fittest. And do you want to know what the first paragraph of the first entry read? Of course you do. It was Wikipedia, naturally, and here's that first paragraph. Odd how it seems germane to this very conversation, don't you agree?

"Survival of the fittest" is a phrase that originated from an evolutionary theory as a way of describing the mechanism of natural selection. It is more commonly used today in other contexts, to refer to a supposed greater probability that "fit" as opposed to "unfit" individuals will survive some test. In these contexts, "fit" refers to "best adapted to the current environment," which differs from common notions of the binary 'fit' and 'unfit.'[citation needed] These ideas are not related to the biological concept of fitness (defined as reproductive success) which has led to popular misconceptions about the meaning of the phrase. In Darwinian terms the phrase is best understood as "Survival of the form that will leave the most copies of itself in successive generations."

You see, Randy, what you've been told in this thread this whole time, that your conception of "fittest" is wrong and doesn't comport with the evolutionary context of the term, is specifically mentioned as wrong in the first paragraph of the first entry of a google search on the topic.

You seem to have researched differing views on evolution about as diligently as you've researched those other religions you claim to have investigated before settling on Catholicism as the most reasonable faith.

The reason we know about certain cultures such as the Spartans, the Visigoths, the Mongols, etc. is because they dominated those around them and survived. And within those "small groups", the alpha male led the group and passed on his genes through the offspring of the females he wanted. 

And this is based on what? Link to a reputable source for each of these claims, please.

But the lacuna is the transition from "survival of the fittest" to feeling warmth and empathy toward the weak and less fortunate members of the group.

Except that what you're being told has support, and what you're asserting doesn't. Your misunderstanding of simple phrases in the theory lead me to believe that your education in it is woefully inadequate -- or that you've read with filters in order to protect cherished ideas that cannot withstand the force of facts.
