Abstract Development can be altered to match phenotypes with the environment, and the
genetic mechanisms that direct such alternative phenotypes are beginning to be elucidated …

Plasticity is a widespread feature of development, enabling phenotypic change based on the
environment. Although the evolutionary loss of plasticity has been linked both theoretically …

Polyphenism is a type of developmental plasticity that translates continuous environmental
variability into discontinuous phenotypes. Such discontinuity likely requires a switch …

Neanderthal foot bone proportions and morphology are mostly indistinguishable from those
of Homo sapiens, with the exception of several distinct Neanderthal features in the talus. The …

Living birds (Aves) have bodies substantially modified from the ancestral reptilian condition.
The avian pelvis in particular experienced major changes during the transition from early …

Animals consume a wide variety of food sources to adapt to different environments.
However, the genetic mechanisms underlying the acquisition of evolutionarily novel feeding …

Some nematode predators and parasites form teeth-like denticles that are histologically
different from vertebrate teeth, but their biochemical composition remains elusive. Here, we …

Developmental plasticity facilitates morphological and behavioral novelty. Nematodes have
emerged as a powerful model to study developmental plasticity and its evolution. Here, we …

Tadpoles can respond to perceived predation risk by adjusting their life history, morphology,
and behavior in an adaptive way. Adaptive phenotypic plasticity can evolve by natural …

Nematodes show an extraordinary diversity of mouth structures and strikingly different
feeding strategies, which has enabled an invasion of all ecosystems. However, nearly …
