Tooth length is influenced by natural selection
when you have healthy teeth If you lose one
tooth chances are your other tooth will be
crooked until that tooth grows back in, Your
teeth all help each other keep each other strait.
But if you are not taking care of your teeth than
your teeth will not be strong enough to grow
longer or any bigger.
Well depending on what the environmental change is the organisms will have to adapt, or move. if they don't they may not survive.
