While that's an interesting perspective, the argument is diminished by the fact that sexual reproduction existed long before internal fertilization, so there was no "injecting" for the first 1.5 billion years of sexual reproduction.
- gumby 4y agoWell, those early eukaryotic mixings did involve an exchange of genetic material though perhaps it was less "injection" than letting things drift back and forth between the two cells for a while. Of course by then viruses were already busy doing their genetic injection thing, but we tend not to consider it sexual, even though it is reproduction. Humans love to be bigoted about these kinds of distinctions!
