Amphibian to Reptile Evolution — NEET Biology
📚 Practice ConceptThere are no specimens of these left with us. However, these were ancestors of modern day frogs and salamanders. The amphibians evolved into reptiles. They lay thick-shelled eggs which do not dry up in sun unlike those of amphibians. Again we only see their modern day descendents, the turtles, tortoises and crocodiles. In the next 200 millions years or so, reptiles of different
Which of the following statements are correct? S1: The Mesozoic era is widely recognized as the 'Age of Mammals' due to their rapid diversification. S2: Oxygen production on Earth began with the appearance of the first cellular forms of life approximately 2000 million years ago. S3: Amphibians evolved into reptiles, which successfully colonized land partly due to their ability to lay thick-shelled eggs that resist desiccation. S4: The extinction of dinosaurs, leading to the rise of mammals, occurred about 165 million years ago. S5: The emergence of modern Homo sapiens is associated with the period between 75,000-10,000 years ago, during the last ice age.
