The Lizard's Tale 102: Does Evolution Repeat Itself?

Synopsis

Anoles from Cuba, Hispaniola, Jamaica, and Puerto Rico exhibit remarkable physical similarities, a phenomenon known as ecomorphism. Researchers, including evolutionary biologists from the University of California, Santa Barbara, investigate whether these similarities arose from a single evolutionary event on one island or developed independently across the islands. Through a combination of physical measurements and DNA analysis, the study aims to clarify the evolutionary history of these lizards, enhancing the understanding of species adaptation in isolated ecosystems.
