AB,
You only see it as a fallacy because you try to remove God from the equation
Did you mean to say that?
A fallacy is a fallacy is a fallacy. “A lion is a cat, therefore all cats are lions” is a fallacy whether or not you throw “God” into the mix, and so is circular reasoning.
The logic is quite clear.
Given your form here somehow I doubt it will be, but let’s see…
For evolution by natural selection to work, every incremental mutation involved in the development of each element of our body has to be passed on through natural selection of beneficial mutations,…
Or neutral ones or ones that reduce functionality but not sufficiently to cause extinction provided the mutations are genetically dominant rather than recessive.
…the implying that every incremental mutation has to give sufficient benefit on its own to be passed on by avoiding extinction.
No it doesn’t. You might for example think that weaker eyesight is harmful, but if the species lives in a lightless cave it would make no difference to its survival and continued presence down the subsequent generations if it happened to be dominant.
Mutations are only “beneficial” or “harmful” in relation to the environment the organism occupies.
So members of the same species without one of the incremental mutations in question would need to become extinct in order for this incremental mutation to be incorporated in the future generations. That is how natural selection works. Or I should say, that is how natural selection is meant to work.
No it wouldn’t and no it isn’t. And it wouldn’t and it isn’t because, eventually,
speciation occurs – generally when the daughter organism can no longer breed with the parent organism.
Why is this difficult for you (and where is Richard Forrest when you need him)?
