Whether we see the changes or not, the human species will continue to evolve naturally over time. The constant advancement in technology today has always played a key role in our evolution process, and the possibilities in today’s generation has both helped and hurt our world. As populations have become larger , genetic drift has become less common in our species. Our many ways of transportation we have today has allowed us to become more connected to others through traveling all over the world. This travel has allowed many different cultures to meet one another and affect  ways of living, as well as influencing others by their different behaviors and biologically speaking, allowed their genes to collide and encourage gene flow to create an even more diverse population. This technological ability and transportation has also allowed others food resources to be sold to different places of the world, that may have ever had these things on their own. Having these foreign foods in other areas of the world can lead to the spread of ingredients for meals for humans, animals, or even kinds of medicine which can help improve the environment and their health. 

Although our advanced transportation systems may have created many benefits, it has also had major negative effects on the human population. The ability to travel has caused new diseases arise and have the potential to spread across the world as pandemics. When a disease from another place in the world is introduced to a new environment, it can survive off of those who don’t have the ability to fight it. This is where natural selection begins to take its course in which we have to take action in order to prevent a disease from thriving and making an even bigger impact on that environment. The effects of natural selection on human biology depend on the environment. All aspects of our environment can be modified by culture, which is including disease, food resources, differential reproduction, and climate change. From our many forms of transportation, different toxic gases are released into the air and can harm our atmosphere that is meant to protect us, as well as harm ourselves. These toxins that harm the atmosphere will then also affects climate change, altering the environment’s weather patterns.

When reading the article, ‘Evolution and the Origins of Disease’, I came across an important example of a way humans are evolving. I found the example to be quite interesting because it is through the mechanism of coughing and disease defence in general. When someone is unable to clear something from their lungs will eventually  pass away. The article explained how coughing is an important action in our lives because it gives your body the capacity to feel pain. If we were unable to feel pain, we would be more likely to die quickly. Another way our body helps to keep us alive is by giving us a fever. When your body detects there is a pathogen in it that can potentially harm you, your body naturally increases in temperature to try and kill the pathogen. A part of this section that I found very intriguing was the mechanism behind morning sickness in pregnant women. The induced vomiting is the body’s way of restricting the intake of harmful substances. In the article it said, “Prophet tested this idea by examining pregnancy outcomes. Sure enough, women with more nausea were less likely to suffer miscarriages”. I found that super cool to see how our bodies have evolved in ways to help keep our unborn child safe.
