Conservationists discover hidden diversity in ancient frog family

Research scientists have uncovered hidden diversity within a type of frog found only in the Seychelles, showing that those on each island have their own distinct lineage. The family tree of sooglossid frogs dates back at least 63 million years. They are living ancestors of those frogs that survived the meteor strike on earth approximately 66 million years ago, making them a highly evolutionarily distinct group.
