His theory is based on the assertion that through evolutionary history, men have always been "mildly polygamous".
金博士的這番理論建立在人類進化史之上:人類一直以來都傾向擁有多個伴侶。
That has changed today, however, and Dr Kanazawa explained that entering a sexually exclusive relationship is an "evolutionarily novel" development for them.
然而如今這種傾向有所改變。金博士解釋說,只忠于一個伴侶的情況從進化的角度來說是比較“新奇”的。
According to his theory, intelligent people are more likely to adopt what in evolutionary terms are new practices--to become "more evolved".
依他所看,比較聰明的人更加容易順應進化趨勢,接受新式的兩性關系模式。
Therefore, in the case of fidelity, men who cannot adapt and end up succumbing to temptation and cheating are likely to be more stupid.
所以說,如果男人不夠忠誠,不能調節自身并抵制誘惑,那么他有可能是因為智商比較低。
