我们建议将人类世定义为最后一个C。2000年的晚全新世和人为土壤的基础上的特点。这与人类世作为最后一个世纪的最初定义形成了鲜明对比。250年（自工业革命以来）和更近的提议，人类世开始于大约5000至8000年前的全新世早期至中期（早期人类世假说）。人类活动的土壤层，其中几种类型是公认的，提供了广泛的陆地地层标志，以确定人类世的开始。土壤圈被认为是人类对整个环境的影响上升到主导地位的最佳指标，因为它强烈反映了早期文明对地球表面大部分地区日益增长的影响。因此，人为土壤的组成被认为比大气组成更适合为人类世提供“金钉”。
We propose that the Anthropocene be defined as the last c. 2000 years of the late Holocene and characterized on the basis of anthropogenic soils. This contrasts with the original definition of the Anthropocene as the last c. 250 years (since the Industrial Revolution) and more recent proposals that the Anthropocene began some 5000 to 8000 years ago in the early to mid Holocene (the early-Anthropocene hypothesis). Anthropogenic soil horizons, of which several types are recognized, provide extensive terrestrial stratigraphic markers for defining the start of the Anthropocene. The pedosphere is regarded as the best indicator of the rise to dominance of human impacts on the total environment because it reflects strongly the growing impact of early civilisations over much of the Earth's surface. Hence, the composition of anthropogenic soils is deemed more appropriate than atmospheric composition in providing 'golden spikes' for the Anthropocene.
