圖邁|700萬年前最早人類祖先|人類演化","Sahelanthropus,tchadensis,乍得沙赫人,古猿,圖邁","## 乍得沙赫人簡介\n\n乍得沙赫人(Sahelanthropus Tchadensis),又稱為乍得人猿,被發現於2001年7月至2002年3月間,是由法國古生物學家米歇爾·布呂內(Michel Brunet)領導的團隊在非洲中部國家乍得北部、撒哈拉大沙漠以南的地方發現的。 主要包括一個相當完整的頭骨化石,暱稱為**图迈(Toumaï)**,乍得當地語的含義為「生命的希望」,發現地為\u003Cspan class=\"marker\" enus=\"Djurab Desert\" lon=\"18\" lat=\"17\" map=\"HB\" zoom=\"4\">德乍臘沙漠\u003C/span>(Djurab)。\n\n乍得沙赫人的時代處於中新世晚期(2300萬年前-533萬年前),曾經浩瀚無比的古\u003Cspan class=\"marker\" enus=\"Mediterranean Sea\" lon=\"18\" lat=\"34\" map=\"HB\"

米,只比現在的華山略高。\n\n這個物種可能是人類與黑猩猩的共同祖先,也是目前(2024)公認最早的人族物種(以兩足行走為條件),生活在大約700萬至600萬年前的非洲中西部(現在的乍得)。 他們生存的環境應該是一片疏林,這個物種應該可以直立行走,從而幫助它們在多樣化的棲息地,包括森林和草原中生存。\n\n目前我們僅發現了乍得沙赫人的頭骨化石,但現有研究表明,該物種同時具有猿類與人類的特徵。 其中猿類特徵包括:腦容量較小(甚至略低於黑猩猩)、面部傾斜、眉骨極為突出、顱骨狹長。 而與人類相似的特徵則包括:細小的尖牙、面部中部較短,以及脊髓開口位於顱骨下方而非後方。 其中,脊髓開口的位置至關重要,這一特徵與非雙足行走的猿類差異顯著。\n\n\u003Cdiv class=\"img-container-article\">\n  \u003Cimg

class=\"description\">图迈的頭骨證明該物種具有小腦和傾斜的面部,就像黑猩猩一樣。 頭骨的大小表明該個體是一隻雄性。 小而平坦的尖牙對於雄性靈長類動物來說是不尋常的,也是人類最早的獨特特徵之一。 頭骨(枕骨大孔)為科學家提供了證據,表明他們能夠直立行走。 图迈生前住在開闊的疏林,這和黑猩猩的祖先所居住的封閉大森林非常相同。\u003C/p>\n\u003C/div>\n\n\u003Cdiv class=\"img-container-article\">\n  \u003Cimg

這一特徵表明,乍得沙赫人的頭部能夠支撐在直立的身體上,與雙足行走密切相關。\n\n\u003Cdiv class=\"img-container-v1\">\n  \u003Cimg src=\"https://image.big-history.online/s00016/000124_1704334678211.png\" alt=\"人类与黑猩猩的枕骨大孔位置对比\" />\n

依據這一重要特徵,學界主流觀點認為:图迈能夠雙足行走,但步態較為原始,不如後來的南方古猿穩健,這也確定了它在人類演化圖譜中的位置。\n\u003C/p>\n\u003C/div>\n\n\u003Cdiv class=\"img-container-article\">\n  \u003Cimg

2020年也有一個研究小組提出了不同意見,認為乍得沙赫人似乎更接近四肢行走而非直立;如果被證實,那麼這個物種就很可能會被移出人類族譜了。 由此也能夠看到,確定人類的演化軌跡並不是一件容易的事情。\u003C/p>\n\u003C/div>\n\n图迈的發現還幫助古人類學家推翻了一個風行一時的「東區故事」理論:在距今約 800 萬年前,東非大裂谷的形成造成人類祖先和黑猩猩之間的物理隔離,人的祖先留在大裂谷以東,而黑猩猩則被分隔在大裂谷以西。 隨後兩者各自演化,最終形成了兩個不同的物種。 但發現圖邁的地點距離大裂谷約 3000 千米,顯然,古人類在非洲的分布要比預想的範圍大許多,因此「東區故事」理論是無效的。\n\n\u003Cdiv class=\"img-container-article\">\n
