Answer:
1. cooler, 2. low brain-to-body-mass ratios, 3. varanid lizards, 4. Paleocene, 5. Carnivora, 6. Paleocene, 7. Oligocene, 8. Pliocene, 9. 5 million, 10. Pleistocene.
Step-by-step explanation:
- The early paleocene was cooler around 25 degrees s compared to the preceding Cretaceous period.
- The species evolved in early paleocene are characterized by the low brain to body ratio.
- The varanid lizard also is known as the komodo dragon or the monitor lizard is known to have evolved later.
- The impact of asteroids at the end of the Pleistocene epoch may have caused the extinction of the species of the land and waters.
- Cats and dogs belong to the carnivorous family of predators as these are nocturnal creatures and have bodies that are well adapted and developed for the prey.
- The Grasslands underwent major changes in the Pliocene epoch.
