"3 Mammals That 'Choose' Their Babies’ Sex."

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.
