Avocados, clinging to a strategy that worked for many millions of years, may find themselves extinct, eventually. Is the speed of evolution an important attribute of survival? The fact that Avocados are still around implies processes that replicate transmission, albeit at lower efficiencies. This is an important learning for more advanced life forms as well. The fact that the form has survived does not mean that it is the fittest, it is just that natural laws have not gotten to them.
Humans should be worried.
