My colleague, Stephen Suomi, has been rearing monkeys in two different ways: randomly separated the monkey from the mother and reared her with a nurse and surrogate motherhood conditions.
Rekan saya, Stephen Suomi, telah membesarkan monyet dalam dua cara berbeda: dipisahkan secara acak dari ibu dan membesarkannya dengan seorang perawat dan kondisi ibu pengganti.
