The formation of societies by individual animals is one of the major transitions in evolution and has occurred independently and repeatedly across the animal kingdom. Much effort has been spent on understanding the causes for the evolution of sociality in general and specific forms of sociality in particular. The question whether sociality entails consequences in terms of evolutionary divergence has received less attention and our understanding of how different forms of sociality might influence macroevolutionary dynamics remains obscure.
Two lines of evidence support that sociality plays an important role in macroevolution. First, there is ample evidence that traits of animal societies directly influence population differentiation and genetic diversity. Population differentiation is a key step during speciation and factors affecting population differentiation may consequently impact speciation. Second, several studies show macroevolutionary consequences of differences in social system traits. However, there remains a lack of synthesis across disparate taxa and a coherent understanding of how sociality influences diversification is still missing.
We aim to fill these gaps and provide a nuanced understanding on the sociality-diversification link across the animal kingdom. Our conceptual framework pictures that different forms of sociality influence population differentiation and genetic diversity, which subsequently alter diversification rates.
I. Which data and analyses are needed to efficiently describe diverse social systems across taxa in a quantitative way?
II. Do these descriptors consistently correlate with measures of genetic structure and diversity across taxa?
III. Is genetic structure and diversity a predictor of diversification and species richness?
IV. Do certain behavioural traits, through their effects on diversity and differentiation, impact diversification patterns on a macroevolutionary scale?
By formulating an explicit framework and addressing all the links within, we will reach a better understanding of the role of interspecific behavioural differences in population dynamics and speciation processes. The force of behavioural variation in macroevolution has been largely ignored and its appreciation will serve as a substantial complement to classical views on the causes of speciation. This will constitute an essential step towards understanding the complex interplay between ecology, social behaviour, and adaptive evolution and the underlying genomic processes.
To accomplish this, we combine meta-analyses across a diverse set of animals, with case studies, for which behavioural and genomic data is collected in wild populations.
