Cryptic variation
WebApr 11, 2024 · Here, we use a comparative approach to investigate how pattern use varies across a phylogeny of 268 species of cryptic and aposematic butterfly larvae, which also vary in social behaviour. We find that longitudinal stripes are used more frequently by cryptic larvae and that patterns putatively linked to crypsis are more likely to be used by ... WebJul 27, 2024 · In the wild, cryptic variation helps fish adapt to life in caves. In the lab, cryptic variation might help a biomolecule bind a new receptor. “Our work can help develop new directed evolution strategies to find innovative biomolecules for biotechnological and medical applications,” says Zheng.
