I have a hard time believing this. The correlations they point out aren't enough to support the conclusions they're drawing. While it makes sense that evolution would select against brains that are too large to pass through the birth canal, shorter gestation is just one of multiple adaptations that could address this.

Yeah, BUT i was two weeks premature and i'm SUPER DUPER smart. Science!

Anecdotally, my sister and I had pretty straightforward births but my younger brother had a devil of a time getting out. He did seem to get the lion's share of the attention but I always chalked that up to him being the last in line and also my parents actually having the time/money to spend.

You got the point, we have an oversized brain size compared to our body, so we have to get birth early to pass through the birth canal. If you take the brain size (compared to the body) as proxy for intelligence of course bigger brain imply early birth. Now, does a bigger brain mean more intelligence?
