I great waste of time and opinion!<quoted text>
If it helps the individual survive then it will be passed on to next generation. If not it dies with the individual.
That's a presumption on your part.
If the cost is greater than the benefit then those mutations wouldn't have survived.
No because natural selection (what survives breeds) clears them out.
Species adapt to an environment. If the environment doesn't change then once fully adapted the species won't change.
But there's always new ones. Evolution never stops.
Like you understand the data?
Your opinion is irrelevant.
Eg."If it helps the individual survive then it will be passed on to next generation. If not it dies with the individual." How simplistic.
The rest is evasive jabber.
