The term that best defines a bacteria that can survive without oxygen is "anaerobic." Anaerobic bacteria do not require oxygen for growth and metabolism.
When we trace evolutionary history we find that the earliest limbs were the fins of fishes, which became sturdier when fish started to colonize the land, and which then adapted to various ecological niches in the form of a bird's wings, a cat's paws, and a dolphin's fins. Evolution is economical in nature, it always seems to prefer to modify an existing structure rather than creating something entirely new. This is quite understandable in terms of natural selection. Existing strucures will appear in various forms because not all individuals of a given species are exactly the same, and the form that best suits some ecological niche is going to be selected. This makes possible gradual change.
