Evolution of flight Water -> land -> air What are the five different styles of becoming airborne? What animals use those styles? - Passive flight o Is something like for dandelion seed or pollen because they are very light compare to its surface area. - Parachuting (descent) o Achieve this by off a high area., getting down without harming yourself. Less than 45 degrees. Its going down but gaining horizontal distance. o Flying gecko - Gliding(descent) o There are many reptile gliders during this time period. o Mammals glide: flying squirrel, flying opossum and flying lemur. - Soaring(ascent) o Active soaring is flying very close to the surface water and to gain some momentum by finding the wave that blows and catches the wind and be able to slingshot themselves up. o Passive soaring is about the chunk of air that goes up and staying with it. o Able to soar and glide without having to spend a lot of energy. -
