      All animals comes from Earth (as far as we know), so the really broad answer to your question is “yes”. But some animals reproduce sexually (two parents) while others reproduce asexually (one parent). Plus they have many different modes of reproduction, think of all the species that lay eggs while most mammals and some fish and reptiles have pregnancies. One way to put it is that we are all different yet all the same (Earthlings).

      The only animals we know of all live on planet Earth. They have evolved into different species all over the world, so for example, now we only get African elephants in Africa (except in zoos!), and we only find tigers in India.

      I hope that helps – do ask another question if I have misunderstood your question.

      Interesting question. I would think the answer is yes and no. Initially, we had only single cell organisms in the seas, for which they group together to form multicellular organisms like the sea sponge. Multicellular organisms evolved over millions of years to become many of the different types of animals that we see nowadays, from amphibians, to reptiles, to birds and mammals.

      This is good video to illustrate what I mean. Enjoy!
