Polyphenic development is thought to play an important role in the evolution of phenotypic
diversity and morphological novelties, yet the evolution of polyphenisms has rarely been …

Polyphenic development is thought to play a pivotal role in the origin of morphological
novelties. However, little is known about how polyphenisms evolve in natural populations …

Facultative expression of alternative male morphologies is thought to allow individual males
to select the phenotype with the highest fitness gain given their competitive status relative to …

Polyphenisms are thought to play an important role in the evolution of phenotypic diversity
and the origin of morphological and behavioral novelties. However, the extent to which …

Onthophagus taurus is a polyphenic beetle in which males express alternative major
(horned) and minor (hornless) morphologies largely dependent on larval nutrition. O. taurus …

Two hypotheses address the evolution of polyphenic traits in insects. Under the
developmental reprogramming model, individuals exceeding a threshold follow a different …

In a wide range of taxa, individuals are able to express strikingly different morphologies in
response to environmental conditions encountered during development. Such …

Phenotypic plasticity has long been proposed to play a major role in the origin and
subsequent diversification of morphological and behavioral novelties. Polyphenism, as an …

The existence of discrete phenotypic variation within one sex poses interesting questions
regarding how such intrasexual polymorphisms are produced and modified during the …

Beetle horns are enlarged outgrowths of the head or thorax that are used as weapons in
contests over access to mates. Horn development is typically confined to males (sexual …
