Wnt signaling is a well-known mode of cell-to-cell communication in multicellular biological organisms. It involves the secretion of small Wnt glycoproteins, by signaling cells, that bind to receptor ...

Many butterflies develop wing patterns that mimic other species to protect themselves from predators. While growing complex body parts like wings involves many genes, the difference between two ...

Butterflies and moths are known to mimic one another in order to adopt warning colors that ward off predators. A new study investigates the genetic machinery behind these adaptations and finds that ...

The female swallowtail butterfly (left) has extra orange spots and a different shape on its wings to mimic species that are toxic to predators, while the male (right) has the standard set of white ...
