Inclusive fitness theory and eusociality

Patrick Abbot, +137 more
- 24 Mar 2011 - 
TL;DR: It is argued that inclusive fitness theory has been of little value in explained the natural world, and that it has led to negligible progress in explaining the evolution of eusociality, but these arguments are based upon a misunderstanding of evolutionary theory and a misrepresentation of the empirical literature.

Stop Signals Provide Cross Inhibition in Collective Decision-Making by Honeybee Swarms

TL;DR: It is shown that a key feature of a brain—cross inhibition between the evidence-accumulating populations—also exists in a swarm as it chooses its nesting site, and that cross inhibition between populations of scout bees increases the reliability of swarm decision-making by solving the problem of deadlock over equal sites.

On optimal decision-making in brains and social insect colonies

TL;DR: In this paper, the authors show that social insect colonies may also achieve statistically optimal collective decision-making in a very similar way to primate brains via direct competition between evidence-accumulating populations.

A Case-Control Study of Dietary and Nondietary Factors in Ovarian Cancer

TL;DR: It is demonstrated that the apparent protective effect of vitamin A in the 30- to 49-year age group (but not dietary fiber) was independent of the nondietary factors analyzed in this study (P less than .05).
