New evidence published today in the journal Science upends decades of evolutionary theory about when animals first walked on ...

Life on our planet began in the water. Eventually, one branch of the fish family tree developed legs and came up on land.

The first four-legged vertebrates did not grow up like tadpoles after all. That idea has shaped the story of life on land for decades. Early tetrapods, the ancient animals that gave rise to mammals, ...

We’ve all seen some version of the classic evolutionary diagram. A fish crawls out of a primordial swamp, sprouts legs, ...

Life on Earth began in water, yet a new fossil discovery suggests that the earliest vertebrates to venture onto land may not ...

Three species that lived about 308 million years ago challenge the idea that the first land vertebrates underwent ...

The first animals to come out of the ocean onto land were creatures resembling modern crocodiles, not amphibians, as previously thought. This is stated in a study published on Thursday, February 12, ...

Palaeontologists have found new evidence that the early ancestors of amphibians, reptiles and mammals did not have a larval ...

If weather predictions from earlier in the week hold true, there could be some extra pedestrians on the road this weekend. They will be very small and motorists are asked to use extra caution on ...

That amphibians are the most imperiled class of vertebrates in the world is largely beyond debate. Such threats as habitat loss and overexploitation for meat or the pet trade are decimating amphibian ...

Disease isn’t the biggest killer of amphibians — that would be habitat loss — but it can be the quickest. And the chytrid fungus (Batrachochytrium dendrobatidis) in particular has been a huge worry ...
