It has always been easily observed that children resemble their parents; the precision of “half” is, I will concede, recent. And many people do want children as a separate desire from wanting sex; I have no reason to believe that this wasn’t the case during earlier historical periods.
“Half” only exists in the sense of the DNA molecules of that new human. That’s why I didn’t say that past humans didn’t recognize any similarity; I said that they weren’t aware of a particularly salient sense in which the child is a “half-copy” (or quarter copy or any fractional copy).
It may be easy for you, someone familiar with recent human biological discoveries, to say that the child is obviously a “part copy” of the parent, because you know about DNA. To the typical historical human, the child is simply a good, independent human, with features in common with the parent. Similarly, when I make a paperclip, I see it as having features in common with me (like the presence of bendy metal wires), but I don’t see it as being a “part copy” of me.
So, in short, I don’t deny that they wanted “children”. What I deny is that they thought of the child-making process in terms of “making a half-copy of myself”. The fact that the referents of two kinds of desires is the same, does not mean the two kinds of desires are the same.
