Question

Which sequence correctly orders the major evolutionary events on the geological timeline given in the chapter?

Accepted Answer

A. {'text': 'Invertebrates 500 mya, jawless fish 350 mya, reptile dominance 200 mya, dinosaurs gone 65 mya', 'label': 'A'}

The chapter places invertebrates around 500 mya, jawless fish around 350 mya, reptile dominance over the following 200 million years or so, and the sudden disappearance of dinosaurs about 65 mya. Only option A preserves the chronological order.
