The process of adaptive radiation—the proliferation of species from a single ancestor and
diversification into many ecologically different forms—has been of great interest to …

Ecological character displacement (ECD), the evolutionary divergence of competing
species, has oscillated wildly in scientific opinion. Initially thought to play a central role in …

Across the great diversity of life, there are many compelling examples of parallel and
convergent evolution—similar evolutionary changes arising in independently evolving …

Soil bacteria produce a diverse array of antibiotics, yet our understanding of the specific
roles of antibiotics in the ecological and evolutionary dynamics of microbial interactions in …

Conventional wisdom holds that synonymous mutations, nucleotide changes that do not
alter the encoded amino acid, have no detectable effect on phenotype or fitness. However, a …

There have been a variety of approaches taken to try to characterize and identify the genetic
basis of adaptation in nature, spanning theoretical models, experimental evolution studies …

Evolutionary adaptation to a constant environment is driven by the accumulation of
mutations which can have a range of unrealized pleiotropic effects in other environments …

Competitors are known to be important in governing the outcome of evolutionary
diversification during an adaptive radiation, but the precise mechanisms by which they exert …

Can a population evolved in two resources reach the same fitness in both as specialist
populations evolved in each of the individual resources? This question is central to theories …

Local adaptation seems to be common in natural systems, but the genetic causes of its
evolution remain poorly understood. Here we characterize the genetic causes of trade-offs …
