Intrafamily and intragenomic conflicts in human warfare
(2017-02-22) - Journal article,
Recent years have seen an explosion of multidisciplinary interest in ancient human warfare. Theory has emphasised a key role for kin-selected cooperation, modulated by sex-specific demography, in explaining intergroup ...
Short-sighted virus evolution and a germline hypothesis for chronic viral infections
(2017-05) - Journal article,
With extremely short generation times and high mutability, many viruses can rapidly evolve and adapt to changing environments. This ability is generally beneficial to viruses as it allows them to evade host immune responses, ...
The meaning of intragenomic conflict
(2017-11-06) - Journal article,
Recent years have seen an explosion of interest in genes that function for their own good and to the detriment of other genes that reside in the same genome. Such intragenomic conflicts are increasingly recognized to ...
Intragroup and intragenomic conflict over chemical defense against predators
(2018-03) - Journal article,
Insects are often chemically-defended against predators. There is considerable evidence for a group-beneficial element to their defences, and an associated potential for individuals to curtail their own investment in costly ...
Monogamy promotes altruistic sterility in insect societies
(2018-05) - Journal article,
Monogamy is associated with sibling-directed altruism in multiple animal taxa, including insects, birds and mammals. Inclusive-fitness theory readily explains this pattern by identifying high relatedness as a promoter of ...
Misconceptions on the application of biological market theory to the mycorrhizal symbiosis
(2016-05-04) - Journal item,
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 ...
Mating ecology explains patterns of genome elimination
(2014-12) - Journal article,
Genome elimination – whereby an individual discards chromosomes inherited from one parent, and transmits only those inherited from the other parent – is found across thousands of animal species. It is more common in ...
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 ...
Simultaneous failure of two sex-allocation invariants : implications for sex-ratio variation within and between populations
(2015-07) - Journal article,
Local mate competition (LMC) occurs when male relatives compete for mating opportunities, and may favour the evolution of female-biased sex allocation. LMC theory is among the most well-developed and empirically-supported ...
