    I have been wondering for a while if insects do breath, have a heart, etc. This video answered all these questions and a lot more. Great concise video!

    Yes, they are ancestral to the Arthropods which include insects, spiders, crabs, etc. They have been thought to be a link between the Annelid worms and Arthropoda. I am not sure if this is what current systematics still thinks now that we have genetic analyses to help follow trends in gene evolution, but I thiink it is.

    This is actually a grasshopper, but they and crickets are related. Yes, the terms and structures described are generally universal. With over a million insect species, there can be many "variations on the themes". For example, some primitive insects lack wings, most species have 2 pairs, but flies have 1 pair. The other pair acts as balancers. So structures differ in appearance between species because of species specializations. I use the grasshopper because it is very typical. Good question.

    Color generally serves two purposes. Protection or mate finding. Roaches and sillverfish live in restricted environments that are usually dark so their colors are drab. There are tree roaches that are green so again it is environmental. Protective coloration is to blend with leaves, sticks, bark,etc, in orders with diverse species in a wide variety of environmental niches. Mate finding is usually blended with sexual dimorphism where the male attracts the female, e.g. Lepidoptera,

    Yes, Onychophora are early relatives of the Arthropoda to which insects belong.

    Amazing but will you explain text color morphs are so varied among grass hopers compared to mites silver fish or roaches for example?
