Social Learning Mechanisms and Cumulative Cultural Evolution: Is Imitation Necessary?

Abstract: Cumulative cultural evolution has been suggested to account for key cognitive and behavioral attributes that distinguish modern humans from their anatomically similar ancestors, but researchers have yet to establish which cognitive mechanisms are responsible for this kind of learning and whether they are unique to humans. Here, we show that human participants' cumulative learning is not always reliant on sources of social information commonly assumed to be essential. Seven hundred participants were organized into 70 microsocieties and completed a task involving building a paper airplane. We manipulated the availability of opportunities for imitation (reproducing actions), emulation (reproducing end results), and teaching. Each condition was independently sufficient for participants to show cumulative learning. Because emulative learning can elicit cumulative culture on this task, we conclude that accounts of the unusual complexity of human culture in terms of species-unique learning mechanisms do not currently provide complete explanations and that other factors may be involved.

The Impact of the Recent Migration from Eastern Europe on the UK Economy

Abstract: UK population growth over the last thirty-five years has been remarkably low in comparison with other countries; the population grew by just 7% between 1971 and 2004, less than all the other EU15 countries except Germany. The UK population has grown at a faster pace since the turn of the millennium driven primarily by changes in net migration, and in particular from an influx of migrants from eight East European (A8) countries. There appears to be consistent evidence from the Worker Registration Scheme and National Insurance Number applications that approximately 500,000 migrants from the A8 countries had come to work in the UK between May 2004 and late 2006. But other sources suggest approximately half of these workers have likely returned to their country of origin. We argue that, at present, it appears that A8 immigration has tended to increase supply by more than it has increased demand in the UK (in the short run). This migration flow, we argue, has acted to reduce inflationary pressures and to lower the natural rate of unemployment.
