Understanding the relationship between human evolution and environmental changes is the key to lifting the veil on human origin. The hypothesis that environmental changes triggered the divergence of humans from apes (ca. 9.3–6.5 million years ago, Ma) has been poorly tested because of limited continuous environmental data from fossil localities. Lufengpithecus (12.5-6.0 Ma) found on the southeastern margin of the Tibetan Plateau (SEMTP) across the ape–human split provides a good chance for testing this hypothesis. Here, we reconstructed the habitats of L. keiyuanensis (12.5–11.6 Ma) with comprehensive vegetation, climate, and potential food web data by palaeobotanical evidence, together with other multidisciplinary data and partly tested the environment-driven hypothesis by revealing the living conditions of Lufengpithecus. A detailed comparison of hominoids on different continents reveals their behaviour and fate divergence across the ape–human split against the background of global climate change, i.e., the stable living conditions of SEMTP not only provided a so-called ‘refuge’ for arboreal Lufengpithecus but also acted as a ‘double-edged sword’, preventing their further evolution while vegetation shifts in East Africa probably stimulated the emergence of human bipedalism, and the intense climatic changes in Europe possibly prevented those hominoids from surviving that time interval. Our findings provide interesting insight into the environmental impacts on the behavioural evolution of hominoids.

古植物学证据揭示了东亚中新世禄丰古猿的生活条件

了解人类进化与环境变化之间的关系是揭开人类起源面纱的关键。由于来自化石产地的连续环境数据有限,环境变化引发了人类与类人猿的分化(大约 9.3-650 万年前,Ma)的假设没有得到很好的检验。在青藏高原东南缘(SEMTP)发现的陆丰古猿(12.5-6.0 Ma)横跨猿-人分裂,为检验这一假设提供了一个很好的机会。在这里,我们重建了 L. keiyuanensis (12.5–11.6 Ma) 的栖息地,利用古植物学证据的综合植被、气候和潜在食物网数据,以及其他多学科数据,并通过揭示禄丰古猿。对不同大陆上类人猿的详细比较揭示了它们在全球气候变化背景下的猿-人分裂行为和命运差异,即SEMTP稳定的生存条件不仅为树栖禄丰古猿提供了所谓的“避难所”,而且也起到了“双刃剑”的作用,阻止了它们的进一步进化,而东非的植被变化可能刺激了人类两足动物的出现,而欧洲强烈的气候变化可能阻止了这些类人猿在那个时期生存下来。我们的发现为了解环境对类人猿行为进化的影响提供了有趣的见解。SEMTP 稳定的生活条件不仅为树栖陆丰古猿提供了所谓的“避难所”,而且起到了“双刃剑”的作用,阻止了它们的进一步进化,而东非的植被变化可能刺激了人类两足动物的出现,以及欧洲剧烈的气候变化可能阻止了这些类人猿在那个时间间隔中幸存下来。我们的发现为了解环境对类人猿行为进化的影响提供了有趣的见解。SEMTP 稳定的生活条件不仅为树栖陆丰古猿提供了所谓的“避难所”,而且起到了“双刃剑”的作用,阻止了它们的进一步进化,而东非的植被变化可能刺激了人类两足动物的出现,以及欧洲剧烈的气候变化可能阻止了这些类人猿在那个时间间隔中幸存下来。我们的发现为了解环境对类人猿行为进化的影响提供了有趣的见解。欧洲剧烈的气候变化可能阻止了这些类人猿在那个时间间隔内幸存下来。我们的发现为了解环境对类人猿行为进化的影响提供了有趣的见解。欧洲剧烈的气候变化可能阻止了这些类人猿在那个时间间隔内幸存下来。我们的发现为了解环境对类人猿行为进化的影响提供了有趣的见解。
