Okay, got it. (Thank you for this free tutorial!)
Now, if mice suddenly mutated (or got genetically engineered) so that they could
live 200 years and grow as big as elephants, should we expect them to do so in
large numbers, in the wild? Or would something in their natural environment
interact with the Uber-Mice in such a way as to reduce rather than increase
their numbers? --J. R.
