Evolutionary novelty is promoted by a macroevolutionary pulse of developmental plasticity, but is enhanced by secondary fixation, which permits developmental character release and further morphological exploration.

CaMKI and neuroendocrine signaling integrate information about food status to regulate a developmental decision in C. elegans.

A comparative and experimental research refutes the controversial hypothesis that plasticity played a major role in the convergent evolution of Anolis ecomorphs.

Sensory innervation density in the insect associative learning center is set by postsynaptic cells and accomplished by flexible allocation of processes by presynaptic cells.

Structural and functional striatal synaptic plasticity abnormalities occur early in a sensitive developmental period, representing a potential unique endophenotypic traits that increase the risk of manifesting clinical symptoms in DYT1 mutation carriers.

Wings achieve plasticity in size while maintaining robust pattern via ecdysone, which elicits graded responses for growth rates and threshold responses for patterning rates, in the fruit fly Drosophila melanogaster.

The higher amount of cortical immature neurons in brains with expanded neocortices may represent a reservoir of young cells for mammals with reduced neurogenesis.

Social clustering behaviors in Drosophila are closely tied to compensatory mechanisms for developmental traits and adaptive behavior plasticity, requiring early-life social experiences and the memory-encoding neuropeptide signaling pathway.

Lizards that live in the Greater Antilles exploit a large range of skeletal variations to adapt to similar habitats, in defiance of the theory of plasticity-led evolution.
