Sure - but that would require specialised claws and digging physiology, which
would make it more
difficult to run from danger. At the moment the aardwolf is specialised enough
to be able to subsist
largely on termites, but not so specialised that it can't run like the clappers
when it needs to.
Whereas the aardvark doesn't have the luxury of speed to escape danger. The
specialised giant anteater is slower yet again.
