When reading the article, I was surprised to not see the other studies mentioned alongside the strict survival results. In developed/industrialized countries, the number of years a child has an involved father predicts their future income, even after controlling for education level, total family income, etc. Of course, these are in environments where survival is not exactly a close call. Edit to add: I don't know if the results were able to be replicated in non-WEIRD societies.
