Homo Sapiens
The last animal I have decided to write about is one that most people do not even consider an animal, but something higher than. This species has managed to colonize each continent and even go off the planet even though it does not possess any great physical defense. The animal that I am talking about of course is the modern human. Most people do not consider us to be humans even though that is exactly what we are. We reproduce, get our nutrients, have similar anatomy, and have similar problems like disease just like most animals but for some reason popular culture has made the use of the word animal to not be equated with humans as well. Humans are coelomate organisms which means that they have a fluid filled space other than the gut in their internal anatomy. They reproduce sexually and are dioecious which means that they have separate sexes. Humans are vertebrates which means they do have an internal skeleton. Humans have great power over reasoning, logic, and communicate to a great capacity. This has allowed them over thousands of years to make an interconnected community that spans the globe. This has happened because humans were able to create languages that allowed them to articulate their ideas to one another. Using language they were able to create writing to preserve ideas across lifetimes, so that knowledge could be built upon. What really started all of this though is that humans were able to create their own food supply, and stop relying on natural resources through farming. This allowed humans to create societies and begin working on things other than simply surviving by getting food. Humans move through a neuromuscular system. They have a complete digestive system. Humans are omnivores so they eat both animal and plant matter. Humans are very unique in the fact that they are able to impact the world so much. They have been able to change the world to fit their needs, instead of adapting to fit the changes that occur in the world. That is what really sets them apart from other animals, and is how they have been able to spread out so far even though they have no physical adaptations that make them threatening or well adapted to survive in certain places. Humans also have almost no predators, and are able to kill most animals that kill them, so they are a top predator even though they have no adaptation like those of other top predators such as large teeth, claws, massive strength, or great speed and dexterity.
