My Inner Fish

The primary topic of this video series, My Inner Fish, was evolution. The evolution in this video series specialized in fish to reptile to mammal to human. We learned about evolution and Earth's timeline in previous units, but from a much broader perspective and not as much focus on the evolution of humans. We also learned in the video about the evolution of certain human traits, which we did not do as much in different units.
"Why are mass extinctions important?"
Mass extinctions are important because so many organisms disappear from the face of the Earth forever, drastically changing the Earth's present and future. Also, because mass extinctions destroy so many large organisms, it gives opportunity to smaller organisms to grow and possibly evolve more. A question I have is "Did more large organisms die off in mass extinctions than small organisms?"
"What event needed to take place for the mammals to emerge and truly flourish?"
The extinction of the dinosaurs needed to take place. With the dinosaurs gone, mammals had less predators and more room to grow and expand throughout the area. A question I have is "how did reptiles do once the dinosaurs passed?
