Study: Breeding Adaptations Help Tree Frogs Thrive in Different Climates

Amphibians evolved from a fish ancestor that had functional lungs and bony lobed fins, which helped them become the first vertebrates to conquer land. Keeping these earlier trails, today’s frogs and toads also have larvae with gills that need an aquatic environment until they transform into air-breathing adults. But this unique feature hasn’t restricted members of the frog family Rhacophoridae from branching out into a wide range of environments, thanks to the adaptation of different reproductive methods, a new study shows.
