The genetical theory of multi-level selection
(2015-02) - Journal article,
The theory of multi-level selection (MLS) is beset with conceptual difficulties. Whilst it is widely agreed that covariance between group trait and group fitness may arise in the natural world and drive a response to “group ...
The meaning of death : evolution and ecology of apoptosis in protozoan parasites
(2011-12) - Journal item,
The discovery that an apoptosis-like, programmed cell death (PCD) occurs in a broad range of protozoan parasites offers novel therapeutic tools to treat some of the most serious infectious diseases of humans, companion ...
Evolution of Helping and Harming in Viscous Populations When Group Size Varies
(2013) - Journal article,
Recent years have seen huge interest in understanding how demographic factors mediate the evolution of social behavior in viscous populations. Here we study the impact of variation in group size on the evolution of helping ...
Resource supply and the evolution of public-goods cooperation in bacteria
(2008-05-14) - Journal article,
Background: Explaining public-goods cooperation is a challenge for evolutionary biology. However, cooperation is expected to more readily evolve if it imposes a smaller cost. Such costs of cooperation are expected to decline ...
Haplodiploidy and the evolution of eusociality : split sex ratios
(2012-02) - Journal article,
It is generally accepted that from a theoretical perspective, haplodiploidy should facilitate the evolution of eusociality. However, the "haplodiploidy hypothesis" rests on theoretical arguments that were made before recent ...
Haplodiploidy and the evolution of eusociality : split sex ratios (vol 179, pg 240, 2012)
(2012-04) - Journal article,
Dynamics of sex ratio and female unmatedness under haplodiploidy
(2014-05) - Journal article,
Haplodiploid sex determination allows unmated females to produce sons. Consequently, a scarcity of males may lead to a significant proportion of females remaining unmated, which may in turn give rise to a surfeit of males ...
(2015-08) - Journal item,
The first American Naturalist appeared in March 1867. In a countdown to the 150th anniversary, the editors have solicited short commentaries on articles from the past that deserve a second look.
The constant philopater hypothesis : a new life history invariant for dispersal evolution
(2016-01) - Journal article,
Surprising invariance relationships have emerged from the study of social interaction, whereby a cancelling-out of multiple partial effects of genetic, ecological or demographic parameters means that they have no net impact ...
Haplodiploidy and the evolution of eusociality : worker revolution
(2014-09) - Journal article,
Hamilton suggested that inflated relatedness between sisters promotes the evolution of eusociality in haplodiploid populations. Trivers and Hare observed that for this to occur, workers have to direct helping preferentially ...
