Subject: Why are there so many kinds of plants and animals on earth?

What are the chances that so many interdependant plants and animals (and many 
more now extinct) would all exist at the same time and place with all of the 
necessary elements to live for a designated period of time and then to reproduce 
each with a compatable species having both male and female? It would be asking 
to much to ask for a mathamatical calcu- lation of the ratio of the possibility 
of this happening. Maybe you could just give me a general idea of what the 
chances are.  There are many more factors that can be entered into this 
equation.  But this is a good start.
