Being a Human Biology major, I have learned quite a bit about evolution in the various biological science courses I have taken. In addition, I remember learning about evolution throughout grade school because it was included in the science curriculum for my school district. Because I was introduced to the theory of evolution at a young age, I haven’t questioned it very much, instead, I accepted it as fact. The theory of evolution is a controversial topic and some simply do not believe in it or have conflicting beliefs with it. Personally, I do not, and I fully believe the theory of evolution. I find it interesting to listen or read about other’s theories of evolution and how they make sense of it, so I’m looking forward to reading blog posts for Sunday’s comments. As stated in the article, evolution is a theory that ties together the biological sciences and biological science would be extremely complicated and more difficult without this theory. Human variability is a topic that I can first remember learning about during high school biology when we discussed the basics of genetics and inheritance. This fall, I am required to take a genetics class to complete my graduation requirements, so I will hopefully be even more knowledgeable about human variation after completing that course. Other than in high school biology, variation was a large focus of two general biology courses I took freshmen year of college. In that class, meiosis was covered (the creation of gametes that are haploid) and eventually we discussed how the how gametes combine to make a diploid cell that contains ½ maternal and ½ paternal DNA, which causes an offspring to have a mix of traits and different variation. Another source of human variation that was discussed in general biology was mutation. There are multiple types of mutation that range in severity and the amount of variation that it can cause. I enjoyed learning about mutations because there are many types and it is interesting to see the effect of one small mutation. I also find it interesting that mutations can be beneficial or harmful to organisms. A topic mentioned in the article “Why Should Students Learn Evolution?” as well as a major focus of a microbiology course I recently took is antibiotic resistance. Antibiotic resistance is a perfect example of evolution that is easily observed and extremely common for people to experience. This is a very serious issue because bacteria and other microbes within the human body can cause dangerous health complications if untreated and due to antibiotic resistance, some of these complications are becoming more difficult to control and cure. I like that the article also delves into how the theory of evolution is a unifying theory of biological science. I totally agree that without the theory, a lot of things simply would not make sense. Overall, the readings and videos for this week were very interesting to me, but also the information given was sort of a repeat of things I have previously learned, because evolution and variation is a huge focus in so many of my classes.
