Dolphins can have conversations underwater, bats can see with sound, and birds breathe through hollow bones to fly. What if humans could do those things? Would it be worth evolving as a species to talk underwater or fly?
Would it be in our best interest to transform in ways suited for marine or avian life or is it better to simply evolve our existing strengths? If we take Darwin at his word, every species should evolve based on its environment, needs, and challenges, in order to thrive – not the needs, environment, and challenges of other species.
