The film discusses the evolution of amphibians, highlighting their origins from fish-like ancestors that adapted to land during the Devonian period. It explains how these primitive animals ...

The first tetrapods (animals with four legs) were almost certainly amphibians, ... The Devonian ended with a series of mass extinction events that killed between 70% to 80% of all life on Earth.

The origin of four-limbed animals known as tetrapods was thought to be fairly straightforward: Fish flopped onto land in the Devonian, evolved, and eventually diversified into the reptiles, birds ...

Amniotes are thought to have diverged from amphibians at the dawn of the Carboniferous period, about 355 million years ago. Mammals would diverge from reptiles and birds only 30 million years later.

The team believes that amphibians and ammonites split apart further into the Devonian period and were likely a contemporary of the primitive, transitional “fishapod” called Tiktaalik.

Amphibians evolved in the Devonian Period and were top predators in the Carboniferous and Permian Periods, but many lineages were wiped out during the Permian-Triassic extinction.
