Dr. Strangelove,
I found a  missing 'link' and here it is     https://en.wikipedia.org/wiki/Piltdown_Man
Most scientists believed that nonsense at the time out of a strong desire to find 'proof' for evolution.  Years from now I think people will look back and see a similar desire today for proving 'man-made' global warming at any cost.  I'm just not buying it.  I do believe the climate may be changing, but in the course of millions of years, most of them being  without humans, this is a normal occurrence. Ice ages and a  greenhouse climate were all a part of our history. Thru it all,  life survived and God willing, it will continue to survive and maybe even thrive.
