| | Human Kin Investment as a Function of Genetic Relatedness and Lineage by Gregory D Webster (Site not responding. Last check: 2007-10-06) |
 | | Relatives of a direct lineage are those who are direct descendents or progenitors of the target individual (e.g., grandparents, parents, children, grandchildren), whereas peripheral relatives refer to those who are genetically related to the target, but are neither direct descendents nor progenitors of the target (e.g., siblings, aunts/uncles, nieces/nephews, cousins). |
 | | The purpose of the present studies was to assess the strength of the genetic relatedness by lineage interaction using a survey method (Study 1), to replicate this effect in a subsequent survey study (Study 2), and to observe this effect in actual inheritances (Study 3). |
 | | Lineage was also a strong predictor, with direct lineage relatives receiving a greater share of the lottery than peripheral relatives. |
