新石器时代在欧洲的扩张是从近东逐渐扩展到整个欧洲大陆的。在北方欧洲，观察显示，与欧洲大陆的其他地区相比，新石器时代前沿的速度有所减缓。有人认为，北方狩猎采集者人口密度高可能是这一减缓的主要原因。最近，一个数学模型描述了这一提议，该模型考虑到：（i）中石器时代人口对新石器时代人口在其领土上前进的阻力，以及（ii）由于对空间和资源的竞争，人口增长动力学受到限制。但这两种效应对利差放缓的作用并不相同。事实上，在这里，我们表明，对人口增长动力的限制似乎是北方欧洲农业扩张延迟的主要原因。(C)2012爱思唯尔有限公司保留所有权利。
The expansion of the Neolithic transition in Europe took place gradually from the Near East across the whole continent At Northern Europe, observations show a slowdown in the speed of the Neolithic front in comparison to other regions of the continent. It has been suggested that the presence of high population densities of hunter-gatherers at the North could have been the main cause for this slowdown. This proposal has recently been described by a mathematical model that takes into account: (i) the resistance opposed by the Mesolithic populations to the advance of Neolithic populations in their territory, and (ii) a limitation on the population growth dynamics due to the competition for space and resources. But these two effects are not equally responsible for the slowdown of the spread. Indeed, here we show that the limitation on the population growth dynamics seems to have been the main cause of the delay of the expansion of farming in Northern Europe. (C) 2012 Elsevier Ltd.
