也許他們是為了尋找食物而出走,或者僅僅是出於漫遊的渴望。但在某個時候,早期人類離開了他們的非洲家園,開始殖民世界其他地區。科學家們才剛剛開始形成對這些早期遷徙時間的理解。《自然》雜誌今天報道的發現可能因此為這個問題提供一些亟需的光芒。

由中國科學院北京分院的朱日祥領導的研究人員,已經將從中國北方泥河灣盆地挖掘出的大量石器工具的年代確定為136萬年前。因此,這些被認為是直立人的手工藝品的遺骸,提供了東北亞最早的人類證據。過去,由於缺乏適用於同位素年代測定方法的材料,東亞舊石器時代遺址的年代一直存在爭議。但朱的研究團隊使用所謂的磁性地層學方法得出了他們的年代估計。

團隊寫道:“工具製造者向[至少北緯40度的緯度]的擴散,意味著東亞早更新世的人類群體能夠適應多樣化的氣候環境。” 事實上,這些勇敢的探險家似乎已經從熱帶非洲出發,為當時加劇的氣候變異性做好了準備,包括中國北方間歇性的乾旱。

Kate Wong is an award-winning science writer and senior editor at 大眾科學 focused on evolution, ecology, anthropology, archaeology, paleontology and animal behavior. She is fascinated by human origins, which she has covered for more than 25 years. Recently she has become obsessed with birds. Her reporting has taken her to caves in France and Croatia that Neandertals once called home, to the shores of Kenya's Lake Turkana in search of the oldest stone tools in the world, to Madagascar on an expedition to unearth ancient mammals and dinosaurs, to the icy waters of Antarctica, where humpback whales feast on krill, and on a "Big Day" race around the state of Connecticut to find as many bird species as possible in 24 hours. Kate is co-author, with Donald Johanson, of Lucy's Legacy: The Quest for Human Origins. She holds a bachelor of science degree in biological anthropology and zoology from the University of Michigan.
