Living things have been living on our earth over 600 million years. They can live on our earth because of there adaptation and there camouflage. I learned from the video Survival that a fox can live a long time because some of them can out run a bunny and rabbit, foxes are always living close to humans because humans always have food with them. Other animals like a baby calf has to learn to walk in less then five minutes after is was born and must learn to run as fast as its mother in one day to protect its self from other animals. Other species like a snaping turtle have a tounge that looks like a worm wich makes fishes hungry and then the turtle just snapes the fish to ear.
