Like any structure in an organism, tongues evolved over time through small changes (mutations) which placed each successive individual at a slight advantage within the species. That individual had some advantage, probably longevity, which allowed for greater success in reproduction. This allowed the mutation to be passed on to future generations. The tongue as we know it today, is the result of accumulations of countless mutations over a long period of time.
In terms of what they might look like in a million years - who knows? It is pure speculation - can you think of a new 'model' of the tongue that would place an individual at an advantage over other members of the species and allow them to be more successful in terms of reproduction/survival etc..?

They probably evolved from specialised muscles at the base of our jaw. Over time, it lengthened because it helped us feed, the more tactile, the better, so there you have it, the modern tongue.
Considering tongues look about the same in most mammals, I'd say they are going to look about the same in a million years time.

They evolve from evil sources , you must know this. They are slippery suckers. All kinds of nasty rubbish slips off of them tongues. In a million years them there tongues and the vessels that hold them will be dust baby. All gone. No more.
