New research indicates that chameleon embryos pass through an early developmental stage featuring a structure previously believed to exist only in mammals. The finding suggests that aspects of early embryonic development are more widely shared across vertebrates than scientists assumed, prompting a rethink of how these traits evolved and how similar they are between reptiles and mammals.
