We analyzed data from the historic population of the Krummhörn (Ostfriesland, Germany, 1720-1874) to determine the effects of grandparents in general and grandmothers in particular on child mortality. Multilevel event-history models were used to test how the survival of grandparents in general...

On the basis of church register entries from the Krummhörn region (Ostfriesland, Germany, 1720-1874) we looked at the question whether the existence or non-existence of grandmothers had an impact on the reproductive success of a family. We found that fertility (measured by intervals between...

The concept of genetic identity–by–descent (IBD) has markedly advanced our understanding of the genetic similarity among relatives and triggered a number of developments in epidemiological genetics. However, no empirical measure of this relatedness throughout the whole human genome has yet...

Kommunikation und Kooperation zwischen sozialwissenschaftlicher und evolutionär-anthropologischer Forschung ist durch einige Verständigungsbarrieren erschwert. In diesem Beitrag werden die wichtigsten dieser Probleme systematisch geordnet und auf die folgenden Fragen hin analysiert: Wo stehen...

"In the population of the Krummhörn (Ostfriesland, Germany) in the 18th and 19th centuries, paternal death led to an accelerated marriage of his children on average. Three evolutionary explanations are offered for this “paternal absence” effect in the literature, namely (i) the assumption...

In this paper we propose a way to measure the degree of government intervention on forward –from parents to children– and backward –from adult children to elderly parents– intergenerational family transfers (IFT). We carry out a discussion about the possibility of using Generational...
