A gradual, step-wise, physiological/molecular response of eyespot size to temperature is a likely adaptation to seasonal variation experienced in the habitat of Bicyclusanynana butterflies.
Parallel losses of short-wave light sensitivity in diverse bats occurred through independent changes at multiple steps in the conversion of genotype into functional phenotype, including pre-, during, and post-transcription.

Enzyme evolution is reversible on a structural and functional (phenotypic) level, but through a different mutational pathway that leads to genotypic incompatibility with the ancestor.

Treating color patterns in a geometric morphometrics framework reveals rapid rates of color evolution that are explained by a combination of intrinsic organismal features (color variation among patches) and geography within a cosmopolitan radiation of birds.
Phenotypic evolution can originate from variations in very precocious developmental events, starting even before fecundation, during the fabrication of the egg in the mother's gonad.

Mycobacterium tuberculosis, which causes tuberculosis, can evolve rapidly in response to new environments by mutating genetic regulators that control multiple genes at once.

Analyses of allelic- and socially-biased gene expression reveal that suppressed recombination causes most of the expression differences in the social supergene, with only few differences due to socially antagonistic selection.
Single-cell RNA sequencing highlights the influence of host–pathogen interactions and stochasticity on transcriptional and phenotypic variance in lymphoblastoid cell lines derived from Epstein–Barr virus-infected primary B cells.
