The slow changes in traits in organisms, taking tens of thousands of years to yield a visible change in variation as evolution suggests, does eventually trap yourself in to a problem of "Time Riddle" - you just dont have enormous enough of time at hand for all these species to come into being. A quick average time calculation suggests that you should have a new species come into being every 15-20 yrs [just rough average time estimation suggests that in about 1 billion yrs ~50 million distinct species evolved]. Though I believe in evolution but I cant understand this part.
First off all your rate isn't as outrageous as you think, bacteria and single celled organisms can do that. However boru is right, so re-run your calculation with his numbers.
I just got a tad light-headed. I hear 'boru is right' so very, very rarely. I'm giddy with excitement.
