Document Summary
Review: 2 diff kinds of insect flight muscle: synchronous and asynchronous; 2 ways to connect wings: direct and indirect. Indirect flight muscles are contained within the thorax of the animal but don"t attach to the wings; they attach to parts of that thorax, changing the shape of that thorax causing the wings to flap up and down. Thorax here is divided into a pot with a lid; you"ve got a large pot on the bottom and a tergum lid on top, and the wings fit between the top and the bottom. So not directly connected to wings; might not be advantage but it"s a different way (it"s more evolved) Continuing with inverts and how they move on land, 1 thing we find regardless of the invert you look at is that they always have at least 3 legs on the ground at any given time. Always 3 legs on the ground at any given time.
