Aliens

This is not my first visit to this strange and interesting planet. My first visit was around 570 million years ago but these single celled organisms that inhabited the planet were pretty boring but there were creatures with backbones beginning to develop . I decided to come back around 300 million years ago to see what kind a progress these new creatures were making and was shocked to discover huge reptile like organisms inhabiting the planet. I stayed for a while and studied these things called dinosaurs because they were amazing looking. I had to return home for a while and the next time I returned all the dinosaurs were gone! These new animals had taken over. I still see some traces of dinosaurs but they were smaller and different. The planets atmosphere had changed and all kinds of creatures had taken form. One wonderful animal I observed where the apes. They seemed very intelligence and different than all other animals i found. The most prominent animal I came in contact with were called Homo sapiens, or humans.

The humans seemed to be the rulers or leaders of the planet now. Though they are all different colors, shapes, and sizes, they were so different from all the other animals except the apes. They had a lot of things in common and I though that maybe they belonged to the same family or that human could have evolved from the apes. Both humans and apes had prehensile hands, using there thumbs to grasp things. They both have nails not claws, and their eyes are positioned in the front of their heads. They also have similar teeth all with four different kinds. The most interesting similarity between them is the fact that they have single births then have a long maturation period for their children. Both when sitting have their trunks upright and have large brains in comparison to their bodies. They also both are social animals and live together with other members or their kind. Though apes and humans are close in nature they are definitely not exactly the same.

Humans are highly developed creatures. The most distinguishing trait they posses is the ability to walk on two feet all the time and with great ease. Unlike almost all other animals their bodies have evolved to support this type of movement. They also mastered using tools, fire, and agricultural to supply the things they need to survive. In some places the humans still live among animals but in other the animals are forced to live among them. They have zoos and even domesticated
