Good looking couples are much more likely to have daughters while unattractive couples are likely to have sons, reveals a recent study.
Natural beauty can act as a strong marker of reproductive success for females than for males, according to Satoshi Kanazawa, an evolutionary psychologist at the London School of Economics and author of Ten Politically Incorrect Truths about Human Nature.
“Physical attractiveness is one of the strongest determinants of women’s mate value,” said Kanazawa.
"Standards of beauty are both innate and culturally universal, and everybody agrees on who is beautiful and who is ugly just like they agree on who is tall and who is short," he said.
