Are burrowing snakes digging their own evolutionary grave?

Does specializing on particular resources restrict an organism’s ability to adapt to changing environments and increase its chances of extinction? Species adapted to living underground (fossoriality) tend to be highly specialized to their fossorial environment at multiple levels, and such specialization could potentially limit their ability to adapt to new or changing environments. A recent analysis of lizards and snakes found that fossorial snakes have greater chances of going extinct compared to non-fossorial snakes.
