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

Early in development, many animals pick a team—male or female—based on their genetics, and, with time, acquire the ...

(Phys.org) —A University of Arizona biologist researching frog evolution has discovered striking similarity in frog species on different continents and proposes two very different ways that this ...

The realization has big implications for how scientists think about evolution. Phenotypic plasticity offers a solution to the crucial puzzle of how organisms adapt to environmental challenges, ...

A new study led by UCC paleontologists discovered that frogs have conserved their ecology in the last 45 million years. The research is published in the journal iScience. Dr. Daniel Falk, together ...

Call it a grand-phibian. Scientists have unearthed a fossil of the world’s oldest tadpole in Argentina — a shock finding that could alter our understanding of amphibian evolution, experts say.

This newly discovered poison frog may represent an evolutionary step on the pathway towards developing brilliant warning coloration associated with other poison dart frogs. A small reddish-brown frog ...

In five cases where vertebrates evolved monogamy, the same changes in gene expression occurred each time. In many non-monogamous species, females provide all or most of the offspring care. In ...
