I'm on board with survival as well. But it is the mutants that don't survive.
Every single new born of every single species is a "mutant".
YOU, being a human, have an average of some 50-ish mutations in your DNA.
They are killed by gunfire, disease, accidents, etc. so are weeded out and cannot reproduce, although many already have. Their mutant kids will repeat unless they too die prematurely. Sadly modern society allows the mutants to survive much longer than they should (aborted mutant fetuses excepted of course).
Please learn how evolution works and what the word "fitness" means in context of evolutionary biology and how mutation might result int
more or less fitness.
I know for a fact that you've already been lectured on this exact topic right here on these forums. Or at the very very least, you've read posts on here that explained it.
It is really amazing to see how the same falsehoods and "playing dumb" is repeated over and over and over... how creationists are corrected on the exact same points time and again, while a couple days later, when those posts are burried in the pages, they just repeat the exact same falsehoods.
I simply don't get it.
We can repeat a thousands times over "that's not how it works...
this is how it works". And it's only a matter of days, sometimes even just hours, before we are back arguing about the same strawman.
One has to start wondering if it is being done on purpose...
Here's an exercise in honesty for you:
Name an instance of an observed mutation that had a positive effect on fitness either in the lab or in the wild.
I know of at least 3 that are regularly repeated on these forums.
When you gave us an example mutation, then please refer to the post I'm quoting here and then explain how your post is still valid in context of that example of a mutation that increased fitness.
