This book starts with a paradox and ends with a riddle. The paradox notes that the mammal specie with the most capable adults is the mammal specie with the most helpless of babies. Is there a connection? The author contends that there is. He attempts to show how the evolution of the helpless baby has led to reciprocal genetic and behavioural adaptions of the nursing females. In addition, the increasing length of the baby's helplessness resulted in the development of the hominid multi-age brood. The author shows how the Long and Short Birth Interval multi-age broods led to social sharing, unified teamwork, speech, language; and civilisation.画面が切り替わりますので、しばらくお待ち下さい。 ※ご購入は、楽天kobo商品ページからお願いします。 ※切り替わらない場合は、こちら をクリックして下さい。 ※このページからは注文できません。
