We have learned many things about humans over the course of this class. We learned about our origin, how we have physically adapted and changed, and how our behaviors reflect on our past. Humans are continuing to change every day. We interact with new people all of the time because of our advances in transportation. Access to transportation allows us to interact with people that we couldn’t have in the past. We are able to develop connections all over the world. This causes change in the human species. These interactions provide people with more options for mating. Options allow us to choose mates we couldn’t choose in the past and make way for physical changes in offspring.
Another contributor to the changes in humans is disease. Diseases are constantly mutating. They could become unresponsive to antibiotics, treatments, etc. When this happens, it plays the role we learned about “natural selection”. Even though natural selection is not something we witness very often in the United States (due to access to certain amenities) it still exists when disease shows up. It is not possible for humans to be prepared for every curveball, so nature ends up taking its toll.
One other contribution to human change is cultural behaviors. Whether these behaviors are a result of religion, preferences, or social class, they are present and causing slow change among different groups. For example, some religions do not allow its “members” to mate with others outside of that religion. We learned about the Amish. They have physical and environmental differences that others don’t have. They mate within the same group. In instances like this, genes are passed on, over and over again, and remains in that population. These genes can be good, bad, or neither. But if the traits are bad (like sickle cell), and it is continuously passed on, the population will soon be wiped out.
There are a variety of ways humans are continuously changing. As I mentioned, technological advances, disease, and culture contribute to our adaptation. Even though these changes take place very slowly, they are still happening. Eventually, adaptation will lead to evolution, no matter what the species is. Taking the past into consideration, we can imagine how humans may change in the future and undergo another type of evolution.
