Correlations as high as 0.6??? Sounds extremely unlikely to me.

When I see correlations this high between indices such as these, I immediately think of inflation through multiple testing, or collinearity.
@lakens@david_colquhoun thoughts? -
Not sure it should be that surprising. The earlier you start having kids, the more kids you can have, no?
-
Real question. I really have no clue about this beyond high school knowledge about evolutionary biology and my gut feelings.
-
It's the other correlations as well. Around 0.25-0.3 just seems way too high an association for those variables.
-
Ha. I am with you there and that makes me rethink my gut feeling for the other correlation.

Actually, as per the graph, all metrics that relate to larger body size are selected in *both* males and females - it's just that the selection is stronger it in males.
-
Is that higher BMI in muscle, or fat? Also, it's damn hard to find a guy who's not fat, so is that choice, or just tough luck?
-
BMI doesn't care if you're jacked or fat, so it's both. It's not exactly the smartest measure, honestly.
-
Yup. The chart mitigates this problem by also including body fat percentage and hip to waist ratio.
-
Low, or high, body fat percentage? High in women and low in men, is simultaneously assumed, or? What hip to waist ratio? Men with an hourglass figure are selected? Ok, I could click on the article, but it's the Economist

If I read it correctly younger age at first birth goes against reproductive success. It's in negative. The positive things for women are Waist-hip ratio and Age at first period. But not age at first birth.
-
Nope. You’re reading it wrong. The older a woman is at birth of her first child, the fewer children she will have.

Got it. Thanks.

BMI is not inherited genetically, and the demographic transition is still ongoing.
