Since Hamilton published his seminal papers in 1964, our understanding of the importance
of cooperation for life on Earth has evolved beyond recognition. Early research was focused …

Supergenes are genomic regions containing sets of tightly linked loci that control multi-trait
phenotypic polymorphisms under balancing selection. Recent advances in genomics have …

How locally adapted ecotypes are established and maintained within a species is a long-
standing question in evolutionary biology. Using forest and prairie ecotypes of deer mice …

Many organisms have sex chromosomes with large nonrecombining regions that have
expanded stepwise, generating “evolutionary strata” of differentiation. The reasons for this …

Speciation is the process by which barriers to gene flow evolve between populations.
Although we now know that speciation is largely driven by natural selection, knowledge of …

Supergenes are sets of genes that are inherited as a single marker and encode complex
phenotypes through their joint action. They are identified in an increasing number of …

Across a species range, multiple sources of environmental heterogeneity, at both small and
large scales, create complex landscapes of selection, which may challenge adaptation …

The coexistence of discrete morphs that differ in multiple traits is common within natural
populations of many taxa. Such morphs are often associated with chromosomal inversions …

Species commonly exhibit alternative morphs, with individual fate being determined during
development by either genetic factors, environmental cues or a combination thereof. Ants …

Supergenes are clusters of tightly linked genes that jointly produce complex phenotypes.
Although widespread in nature, how such genomic elements are formed and how they …
