A species of butterfly that changes its appearance through the seasons lacks the genetic variation needed to quickly evolve a different response to more unpredictable environmental conditions, such as those expected under ...

Our genes (aka. the genotype) determine our characteristics (aka. the phenotype). Evolution acts on changes in the phenotype, which occur when mutations change the underlying genotype. But what changes to the phenotype can ...

A new model exploring how evolutionary dynamics work in natural selection has found that phenotypic diversity, or an organism's observable traits, co-evolves with contingent cooperation when organisms with like traits work ...
