Quoth Comfort:
“I sincerely apologize for misrepresenting what Darwinian evolution says about the origin of males and females. I have checked out the references you have given me as to what the theory has to say about their genesis, read them again and again, and I still don’t understand what you believe. It doesn’t make sense to me because I can’t reconcile what I see in creation with what you would have me believe about evolution. Still, that doesn’t give me the right to misrepresent your beliefs, even if it was done in ignorance.”
Okay, Comfort has officially admitted that he is too stupid to understand evolution, and that his tripe is an example of the arrogance of ignorance. Well, good. But I think I’ll try to explain anyway. I’m typing this on an iPhone so please excuse typos.
Let’s do a thought experiment where we try to *actually understand* what biologists think. We’re going to do this honestly, though, so no smuggling in creationist assumptions.
Suppose we have a cage (cage 1) that contains a lion, Leo. Because this is a thought experiment, Leo will let us take all the measurements we want. So we write down all the measurements, step out of the cage and see that to its left is another cage, cage 2, containing Leo’s sire and dam. So we go in there, carefully measure the two animals, compare with Leo, and find that he is very similar to his sire.
Good. Now we go to cage 3, containing the sire and dam of the male in cage 2, and we measure again. No surprise; this male is much like his son and the female is much like the female in the next cage. They are clearly of the same species. So we step out and move to cage 4, containing the sire and dam of the male in cage 3 and … you see where I’m going with this.
Well, this is kind of repetitious so we’ll skip over describing the animals in a couple of million cages, but each cage will contain both a male and a female, and they will always be quite similar to the animals in the cages to their left and right. So we reach cage 2,000,000 or so, start the tedious process of measuring, and then come out of our stupor of boredom and realize — wait, this male isn’t a lion! It’s smaller, its coloring is different, it’s less heavily built … what is this thing, and how did it get in the lion cages?
We check our records, and this animal looks much like his son, which looks much like his son, which looks much like … all the way back to Leo. Somehow those small differences, sometimes bigger, sometimes smaller, added up to a large difference in size. Yet there was never a point where we could say, the animals in this cage are lions and the animals in the next cage are not. Further, of course, every cage contains both a male and a female.
So we keep going back, seeing that in each cage the animals are similar to the animals on either side, and then after, say, fifty million generations, we’re looking at rat-sized animals that aren’t really cats, or dogs, or bears, though we could trace their descendants and find that some *are* cats (like Leo), while others are dogs or bears. And still each cage contains both a male and a female.
Now we keep going for hundreds of millions of generations, still observing a male and a female in each cage, still seeing great similarity between the animals in each cage and those in the neighboring cages, and we find some reptilian animals, something like Tiktaalik, some fishes (though not quite like modern fishes) and still there are two animals in every cage.
If we traced forward from here, we would have many paths to follow — we would find modern fishes, frogs, turtles, blue jays, eagles, elephants, cattle, lions … all those animals that Comfort observed as having both males and females.
The various species that have males and females today are descended from species that had males and females. There are species that have lost their males and are female-only, but there are no species that are male-only.
This doesn’t strike me as terribly difficult to grasp. Now why the two roles of male and female evolved in the proto-species, the worm-like invertebrate, well, scientists are working on that. They are not working on the issue of how lions got along without lionesses for millions of years until lionesses evolved.
