About Misconception from Monogamy, evolutionary psychologists David P. Barash and Judith Eve Lipton state we are not the sole couples-connecting variety you to definitely wants to sleep to. Also one of many dogs which have always been labeled as faithful types-nesting wild birds, an such like.-hardly any remain exclusive.
