"3 Mammals That 'Choose' Their Babies’ Sex."
Posted on 08:56 by Unknown
Yes, one of the 3 is the human being.
Interesting use of the word "choose." I assume that's intended to resonate with the right to choose, and the argument is something like: The vaal rhebok and the francois’ langur are doing it too, so we ought go all out with the sex-selection technology — abortions and all. Don't let the beasts get the jump on us!
We used to try to rise above the animals — they also "choose" infanticide and other murder — but that's been turned around. Now, we fuzzily yearn to emulate what we see in the natural world.
And by "see," I mean seeing what we want to see — typical human style. Any other animal indulging in our kind of see-what-you-want-to-see perceptions would have gone extinct long ago.

"Those H's and O's would love to get together and quench, making water, leaving the naked nitrogens to couple..."

"... making N2 which is essentially air. The chemical structure of ammonium nitrate is a depiction of air separating water. We never hear about spontaneous explosions of ammonium nitrate. Why is that?"
Answering that question and explaining why fertilizer bombs work ("because they do make air and water from ammonium nitrate").
