Question

Find one other scientific theory of how life began and tell me about it.?

Answer 1

There is a physics phenomenon where like materials tend to clump together.  I've forgotten what it's called, but it was instrumental in the creation of life.

In the beginning, some three billion years ago, there were inert lifeless amino acids lying around in Earth's water.  But these tended to clump together by that effect I mentioned above.  Somewhere along the line, one or more of these amino acids became activated; so that they began to process matter and replicate using the resulting energy.  And that was the beginning of life.

These early life forms evolved into better eating machines so they could replicate better.  One of the evolutionary events gave some of them the ability to go after food rather than wait for food to come floating by.  That gave the movers a distinct advantage in survivability over the stationary life forms.

Some of the early life forms discovered they could do better if they joined up with other life forms with different, but useful, specialties, like sensing light for example.  Now the two life forms are living a symbiotic existence, each helping the other to process food and replicate...eventually as one species rather than two.

Evolution continues on for the next 3 billion years, bringing new and more sophisticated life forms with improved abilities for feasting and replicating.  Finally, temporarily at the top of the food chain we have homo not so sapiens poised to do itself in with accelerated global warming and make room for the next dominant species on Earth.

Answer 2

One other than "what"?  There is only one scientific theory for the evolution of life on Earth, BUT there are a number of competing hypotheses for the origin.

One is that clay-like minerals became self replicating and ultimately were responsible for the creation of RNA.  This eventually led to DNA, and we're off!  Another says that amino acids, commonly found in interstellar molecular clouds, arrived on Earth with comets.  Again, once those babies were here we were off!  Is this what you mean?
