Collagen is a tangle of hairy stringy protein molecules. This collagen glue is only found in animals and nowhere else. It is sometimes referred to as the sticky tape . It is important in constructing animals because it is the commonest protein in our body and it forms the frame work of our skins. Collagen provides the building blocks for multi-cellular organisms. The origin of collagen is related to the oxidation of the neoproterozoic earth because you need oxygen to manufacture collagen. At the end of the snowball earth, there was a rising amount of oxygen in the atmosphere, allowing cells to manufacture it.
