摘要

气候与人类进化之间的关系错综复杂,其因果机制仍不为人知。在此,我们回顾并综合了目前已知的有关非洲地貌的气候影响因素,主要侧重于过去的 400 万年。我们利用海洋沉积物档案和数据-数值气候模型比较与整合所获得的信息。泛非水文气候的变化存在异质性,受以下因素的共同影响:轨道步调一致的低纬度日照波动;极地冰量变化;热带海洋表面温度梯度;沃克环流;可能还有温室气体。泛非植被变化并不遵循相同的模式,这表明还有其他影响因素,如二氧化碳和温度。我们提醒不要依赖全球或区域气候、环境变化和人类进化之间的时间相关性,并简要提出了泛非气候趋势如何有助于建立新的概念框架,以确定气候/生境变化与类人进化之间的因果机制。

Climate and Human Evolution: Insights from Marine Records.

The relationship between climate and human evolution is complex, and the causal mechanisms remain unknown. Here, we review and synthesize what is currently known about climate forcings on African landscapes, focusing mainly on the last 4 million years. We use information derived from marine sediment archives and data-numerical climate model comparisons and integration. There exists a heterogeneity in pan-African hydroclimate changes, forced by a combination of orbitally paced, low-latitude fluctuations in insolation; polar ice volume changes; tropical sea surface temperature gradients; the Walker circulation; and possibly greenhouse gases. Pan-African vegetation changes do not follow the same pattern, which is suggestive of additional influences, such as CO2 and temperature. We caution against reliance on temporal correlations between global or regional climate, environmental changes, and human evolution and briefly proffer some ideas on how pan-African climate trends could help create novel conceptual frameworks to determine the causal mechanisms of associations between climate/habitat change and hominin evolution.

期刊介绍: The Annual Review of Marine Science, published since 2009, offers a comprehensive overview of the field. It covers various disciplines, including coastal and blue water oceanography (biological, chemical, geological, and physical), ecology, conservation, and technological advancements related to the marine environment. The journal's transition from gated to open access through Annual Reviews' Subscribe to Open program ensures that all articles are available under a CC BY license, promoting wider accessibility and dissemination of knowledge.
