What is Evolution?

    Before I go into detail about my views on evolution, I need to clarify how I will be referring to the term “theory”. To me, a theory in science is based off of varying concepts/fundamentals that explain a specific incidence. Also, I would describe evolution (in relation to organisms) as follows- how species change over time to adapt to their needs. They can change specific features/structures or even their habits to better adapt within their population or their environment. With that clarification, I believe that evolution is both a fact as well as a theory. In my opinion, evolution is a fact since it is evident that animals are not exactly the same as they were thousands of years ago. I think it also counts as a theory since our comprehension of the process is continually developing. As we find more evidence and explanations, we might find some information to be better fit in the future.

    Evidence that supports evolution includes homologous structures, fossils, and genetic makeup. I believe one important thing to remember when talking about evolution is that evolution consists of sharing a common ancestor, not directly one species changing into another. This is where homologous structures have a role; common ancestors are the link for the presence of these structures and can explain how they also share similar function. Fossils depict that species are not the same as they once were, and that they have adapted as time progressed. We can learn about animals that are now extinct. Finally, we can look at DNA to understand evolution. DNA is shared between organisms showing that a common ancestor needed to be present. To examine these evolutionary changes, we can look at genetic makeup.

    Overall, I believe that there are many strong pieces of evidence that make evolution a factual occurrence. A theory to me incorporates evidence, principles, and observations. A theory involves the highest understanding of our insight, making evolution considered to be a theory as well. However, I also believe that our understanding will alter as more evidence is uncovered.

    Hi Prutha
    Well done. I really like how you consciously thought about what theories actually are and how they relate to facts.
    Cheers, Michi

Inbreeding- Module 6.2

       One benefit of inbreeding I can think of is acquiring certain preferred traits. One common example of inbreeding that I can think of is with dogs. When a specific dog breed is wanted or specific traits unique to a particular dog, inbreeding could be used to acquire those. With that, the gene pool would be fairly small and there wouldn’t be many as much genetic diversity. This is when assortative mating would be more common. This is when the preference to choose mates with similar phenotypes increases.      However, inbreeding also comes with many disadvantages. Recessive phenotypes could be more prominent with inbreeding, which could be a negative impact of the recessive trait is damaging. If too many recessive genes are inherited, they will be carriers for varying diseases. With that, there are many underlying health conditions that the animal would be predisposed to.      I guess one factor of inbreeding in terms of evolutio...

Kimura's Theory of Neutral Evolution- Module 7

       The one main difference between Kimura’s theory is that it says that changes in evolution are caused by genetic drift rather than natural selection. Kimura found that the protein polymorphisms observed were formed by genetic drift since their function did not change. Another important aspect of this theory is the removal of newly formed deleterious mutations.      The theory of evolution by natural selection is the one that is more commonly heard of. This theory was proposed by Darwin and it states that species change to adapt to their needs by inheriting heritable traits. One main facet of this theory is that it is assumed that more offspring is produced than the amounts that are able to survive.      They are both similar in the sense that they explain how organisms are able to adapt over time. Both theories describe how alleles are integrated. In Darwin’s theory phenotypes are what induce the change; in Kimura’s theory a ch...

Final Reflection- Module 14

     The overall idea I took away is that evolution is always occurring and there are many mechanisms and conditions that contribute to this. Some aspects can be observable to the eye while others work on a genetic level and make changes that way. Also, the speed of evolution varies, and adaptation is a big part of many populations. One important aspect I learned from the breakout rooms is that there can be multiple perspectives on one topic, and that sometimes there is no one specific answer, especially when hypothesizing about something.      From the R exercises, I learned how different factors such as mating, gene flow, genetic drift, migration, and natural selection impact a population; an important part of genetic diversity is heterozygosity. Even though the coding was difficult at first for me, I am glad I was able to learn this skill set. I was happy when I was able to figure out the coding by myself later in the course. I also learned how importa...
