in my head there are two animals i can think of that are on the brink of an evolutional change. all they need is that factor to change them. like in darwins theory that there is some factor that changes a being hence evolution. these animals are the hippo and the penguin. the hippo and penguin both spend tons of time in the water and there not exactly aquatic creatures. The hippo could have roamed all over the lang but being so big they might have had little to no defenses againts feirce preditors, so they moved underwater to be safer and have changed some but havent made that jump over the gap to become a totally different creature. and the penguin is a flightless bird so maybe once they could have flown but something changed that and then they took to the water well their good swimmers and fishermen and women too

but still there on the edge of that gap waiting for someone or something to give them a push. in our day and age i think it might be upon us to help these creatures change. with all the advances science has come across maybe us humans are that factor darwin talked about. now im not saying that from now on nothign can change unless we do it , im simply saying that these two animals could perhaps acheive their dream and transfer to another beautiful being. thx any comments or questions are welcome thx again cody
