Renewal is not change. each generation does not bring change. If it does on a minuscule basis how many billions of years did it take for man to evolve to what we are today?
That is not the question I answered. My answer was to your question:
""From the moment your are born you are headed for death you are dying you are breaking down."
You were implying that organisms on Earth are winding down, becoming less than their ancestors. In effect dying out. I stated that humans as individuals do not 'wind down' during the first twenty some odd years and that the human species as a whole is not 'winding down' and becoming less than our ancestors.
How many years did it take for man to evolve from what, the Chimp-Human common ancestor? About ~6 million years.
