Please help me with the math.
There are 50 and 500 billion mutations in humans every generation at a rate of 1/10 of 1% rate 2 to 20 million per year.
Woman are born with 2 million eggs out of which 200 to 300 are viable during the reproduction years. On average 2 children per individual.
Out of 500 billion mutations are actually in the germ line?
Then take those numbers and apply to viable eggs then take natural selection to account 2 children produced on average in a generation.
I don't see how it is possible for humans to be anything but humans in the future.
