1. Describe the versions of the appearance of wings in insects. 2. What is the name of the fly’s balance organ? 3. What is the name of a butterfly flying from Canada to Central Mexico for overwintering? 4. List tree-living reptiles that use glide. 5. Who is the ancestor of birds? 6. Versions of the appearance of feathers in birds. 7. What distance do swifts travel from England to Holland in search of food for their chicks? 8. Why do swans fly in pairs? 9. What is the name of the method of orientation in space in bats? 10. List the mammals using glide flight. 11. Give an example of convergent evolution.

1. The emergence of the wings occurred from the lateral outgrowths, dorsal plates. And another theory is that the wings originated from the tracheal gills that ancient insects had.
2. Statocyst. These are bubbles that are submerged under the fly’s body cover. It can also be dimples or bulbous protrusions of the cover.
3. Monarch butterfly.
4. Flying geckos, lizards.
5. Archeopteryx.
6. There is an assumption that feathers in ancient birds appeared due to the growth and lengthening of reptile scales. According to the new version, evolutionary transformation was first associated with the elongation of feathers, then with the development of fringed edges, and then with the appearance of grooves.

8. Swans are believed to mate for life and never part.
9. Ultrasonic echolocation. In this way, bats emit short ultrasonic pulses that help them navigate.
10. Flying squirrel, woolly wings, sifaka, giant flying couscous.
11. Examples of convergent evolution include ichthyosaurus, shark and dolphin. Their body shape and fins converged.
