A duplicated gene evolved into a switch that determines sex in frogs, revealing how evolution can safely reshape critical ...

Biologists have long thought that some frogs evolved to mate on land instead of in water to better guard eggs and tadpoles from predation. New research now suggests that mating on land in many species ...

Water frogs have emerged as a compelling model in evolutionary biology due to their unusual modes of hybridization and reproductive genomics. Interspecific crosses between parental species have given ...

A Brazilian study described in an article published in the journal Salamandra evidences the versatility of amphibians in terms of reproductive modes: their eggs and larvae can develop in at least 74 ...

Travel out of almost any of the major cities of Honshu on an overcast, rain-threatening evening, and head toward rice country. Ribbit, ribbit: The male Hokkaido brown frog mating. There, in the ...
