Agreed.

I would also be curious if she has any areas of interest where she is actually very quick and knowledgeable. If not, that might be cause for concern, but for all we know she just hates the humanities and is actually a wizard at higher mathematics. Especially since she’s young, there’s no real way to gauge whether it’s a lack of general intelligence or just a symptom of complete and total disinterest in a particular subject.

Also let’s not forget that pretty people can often get away with more than average looking people can, so they don’t have quite the same degree of pressure to perform in areas where they’re uninterested. If a quick, dazzling smile can unlock the ability to copy someone else’s homework or get the teacher to grant extra time on an assignment, well, school might be a little easier.

It’s a pros and cons thing. The pros in this case are our upright posture with narrower hips that let us cover long distances more efficiently than most of the rest of the animal kingdom. We can even do things like carry food to eat while walking, which something like an antelope would struggle with. Then a second pro is the whole big brain thing. These two factors did let us take over most of the planet over the course thousands of years, pretty quick work, really.

Then the cons are high mortality in birth, and taking something like 10 years after that risky birth to become even semi-functional at a practical level.
