Multilevel selection analysis of a microbial social trait
TL;DR: This work combines the multilevel partition of the Price equation with a laboratory model system: swarming in Pseudomonas aeruginosa to parameterize a population dynamics model using competition experiments where the cost‐to‐benefit ratio of swarming cooperation is manipulated.
Journal ArticleDOI
In search of general evolutionary principles: Why Darwinism is too important to be left to the biologists
TL;DR: It is proposed here that Darwinism provides a general, meta-theoretical framework for dealing with complex evolving systems, consisting of populations of varied and replicating entities, which are found in both nature and human society.

Suspending disbelief—of Wynne‐Edwards and his reception
TL;DR: Critique of Wynne‐Edwards' views on population regulation and sociality suppose a population of discrete, mutually exclusive groups essential to his thought, yet both his past and present work focus on continually distributed, philopatric populations.
Journal ArticleDOI
The selection differential in quantitative genetics and ess models
TL;DR: A formula of Lande and Arnold (1983) for S, which holds in normally distributed population and which illuminates the relationship between the two models, is extended to the case in which fitness depends also on the average behavior of a local interaction group (equation 12).

Perfect genetic correlation between number of offspring and grandoffspring in an industrialized human population

TL;DR: Using a population sample of identical and nonidentical Swedish twins and their descendants, it is shown that the genetic influences on number of offspring and grandoffspring are identical, supporting the use of reproductive success as a measure of fitness in comparable human populations.
