Amazing Amphibians: On the Border of Two Elements. A conversation with Alexey Semikhatov and Nikolay Poyarkov.

Frogs, toads, newts, and other amphibians are extraordinary animals in many ways. Their history is a fascinating journey back in time, spanning millions of years. The emergence of amphibians marked a fundamentally new stage in the development of the Earth's biosphere – the colonization of land by vertebrates. Life on the border between two worlds fostered the development of a number of remarkable traits, some of which have survived in mammals. When and why did these amazing creatures appear? How do amphibians differ from other animals? What is the secret to their survival? We discuss this and much more with Nikolay Poyarkov, PhD in Biology and Associate Professor in the Department of Vertebrate Zoology at the Faculty of Biology at Moscow State University.
