Demography and the Palaeolithic Archaeological Record

Demographic change has recently re-emerged as a key explanation for socio-cultural changes documented in the prehistoric archaeological record. While the majority of studies of Pleistocene demography have been conducted by geneticists, the archaeological records of the Palaeolithic should not be ignored as a source of data on past population trends. This paper forms both a comprehensive synthesis and the first critical review of current archaeological research into Palaeolithic demography. Within prevailing archaeological frameworks of dual inheritance theory and human behavioural ecology, I review the ways in which demographic change has been used as an explanatory concept within Palaeolithic archaeology. I identify and discuss three main research areas which have benefitted from a demographic approach to socio-cultural change: (1) technological stasis in the Lower Palaeolithic, (2) the Neanderthal-Homo sapiens transition in Europe and (3) the emergence of behavioural modernity. I then address the ways in which palaeodemographic methods have been applied to Palaeolithic datasets, considering both general methodological concerns and the challenges specific to this time period. Finally, I discuss the ability of ethnographic analogy to aid research into Palaeolithic demography.     

Demography and the extinction of European Neanderthals

Causes previously suggested for the sudden extinction of Neanderthals (Homo neanderthalensis) in Europe, starting around 35,000 years ago, comprise food shortage, climatic effects and violence from Modern Humans. The aim here is to formulate a demographic model with reconstructed fertility and death rates, capable of modelling the population development under conditions of changing climate and prey availability, from the early appearance of Neanderthals in Europe about 260,000 years ago to their demise. Parameter variation studies are made for the parameters considered to have the highest uncertainty. Finally, the option of regional migration between northern, middle and southern Europe is added, in order to capture population movements away from a region in response to deteriorating or improving climate. This model accounts for population developments, including the re-population of the Middle and Northern regions of Europe during and after the warm Eem period. However, parameter choices that give plausible results during the initial 210,000 years also predict that the Neanderthals should have survived the latter part of the Weichselian ice age, despite competing for food with Modern Human newcomers during the last part of the period. The conclusion is that other reasons for extinction than climate or starvation must be sought.     

Demography and pronatalism in France in the nineteenth and twentieth centuries

The fear of population decline in France is deep-rooted and complex. With a renewed decline in fertility in the 1970s, fresh concern has shown itself in the multiplication of books and comments, fitting into a pronatalist tradition which can be traced back at least one hundred and fifty years. In reviewing these works, and other new works on the history of population ideas in France, this paper emphasizes both the uniqueness of the French demographic case and the continuity of reactions both official and private. It isolates key periods of concern in the years before the First World War, in the 1930s and the late 1970s. It also draws attention to the proliferation of propaganda, four examples of which are re-published here.     

国共第三次“围剿”与反“围剿”探微

1931年国共在中央苏区展开的第三次“围剿”与反“围剿”,开场和结局都颇具戏剧性,整个“围剿”、反“围剿”进程,直接受制于国内外形势的变化。在国共两大主角的角力过程中,宁粤冲突和九一八事变,某种程度上成为国共武力斗争的搅局者。事实上,1930年代前后,国共之间的许多故事,都可以看到如是因素的介入,国共两大力量之外的“第三者”,为历史的走向增添了更多的变数。     

唐贞观时期社会经济发展程度考略

唐太宗统治的贞观时期(627-649),共23年时间。他的“治武功”,被封建史书赞美为“贞观之治”,也为后世的治史所重视。
