Adaptive Radiation: Contrasting Theory with Data

TLDR
Using modeling approaches, 10 general patterns concerning the temporal, spatial, and genetic/morphological properties of adaptive radiation are identified.

Rapid evolution of reproductive barriers driven by sexual conflict

TLDR
A simple mathematical model is developed describing coevolutionary dynamics of male and female traits involved in reproduction that shows that continual change in such traits at a constant speed is expected whenever females experience fitness loss from having too many compatible males.

TLDR
This work describes the Bateson-Dobzhansky-Muller (BDM) model of speciation that does not require overcoming selection and describes exactly how the probability of speciation, the average waiting time to speciation, and the average duration of Speciation depend on the mutation and migration rates, population size, and selection for local adaptation.

The evolution of female mate choice by sexual conflict

TLDR
A quantitative genetic model is developed showing that sexual conflict over mating indeed results in the joint evolution of costly female mate choice and exaggerated male traits under a wide range of circumstances.

TLDR
This work builds and explores a large-scale, stochastic, spatially explicit, individual-based model of adaptive radiation driven by adaptation to multidimensional ecological niches, and shows that a great majority of speciation events are concentrated early in the phylogeny.

Sympatric speciation by sexual conflict

TLDR
A simple mathematical model is presented that shows that sexual conflict over mating rate can result in two other general regimes, rather than “running away” from males, females can diversify genetically into separate groups, effectively “trapping” the males in the middle at a state characterized by reduced mating success.

The genetics of phenotypic plasticity. V. Evolution of reaction norm shape

TLDR
This model goes beyond previous models by simultaneously permitting any shaped reaction norm and allowing for the imposition of genetic constraints, and it predicts that a population will converge on the genotype with the maximum mean geometric fitness over all environments.

What, if anything, is sympatric speciation?

TLDR
It is argued that testing whether a case fits a particular definition is less informative than evaluating the biological processes affecting divergence, and that this context can be better understood by modelling and measuring quantities, such as gene flow and selection, rather than assigning cases to discrete categories like sympatric and allopatric speciation.
