How Did Amphibians Evolve?

The video explores the evolution of lobe-finned fish, which are considered living fossils. These fish are ancestors of amphibians, the first vertebrates to transition from water to land. Key adaptations for this transition included developing limbs and lungs. The celiacanth and mudskipper illustrate these evolutionary steps. Lungfish, with primitive lungs, provide insight into early land adaptation. Over time, these fish evolved into tetrapods and amphibians, dominating land for millions of years.
