What is the origin of animal creation?

The origin of the creation of animals in general is from water, as Allah Almighty said: "And Allah has created every [moving] creature from water" and "And We made from water every living thing." There is no explicit text in revelation that specifies the exact origin of animal creation, as came regarding the creation of angels from light, jinn from fire, and humans from dust. Knowing the origin of animals does not entail any legal ruling or action.
