what's the name of this theory that tells all living things came from dead organism?

Answer 1

All of the previous answers should be enough to explain. However, if you are talking about the middle ages and their explanations for simple life forms such as worms you may mean the idea of "spontaneous generation." EX: Maggots suddenly appear on rotten meat - must be magic or spontaneous generation. If the hair from a horse's tail falls into a puddle it will turn into a worm - trying to explain their observations using "spontaneous generation."

Answer 2

The Primordial Soup Theory

Answer 3

You may be speaking about the old "Primo Genitur" theory, where they believed mosquitoes came from dead leaves in water, and so forth. Really old, really foolish. The result of poor observation.
On the other hand (as some suggested) you may be referring to the Primordial Soup theory, that says that life on Earth originated in a "soup" of inorganic chemicals that underwent a revolutionary (and unreproduceable) change due to exposure to cosmic radiation or electrical power (from lightning).
In either case, it's just speculation. My thory is that primordial soup should be served before primordial salad, with primorial crackers on the side.

Answer 4

i think you mean the primordeal soup theory, but its not that life came from a "dead organism". think about that, an organism is a living being, and a dead organism is something that was once alive. so what you're saying is that life came from life. but if i'm thinking what i think you're thinking, you mean that life came from organic compounds formed. some people believe that life on earth was started when organic compounds somehow generated a living creature capable of growing, reproducing, and all that. i would say its possible

Answer 5

uhhh....dead theory?

what?

you make no sense
