Evolution Final Project - Top 6 Things I Learned by Ty Young https://padlet.com/tyyoung/n8qmlt55yfo2 A ranked top 6 overview on what I learned during the Evolution Unit in Integrated Biology. en-us 2018-05-21 13:30:21 UTC 2024-10-02 04:54:53 UTC hello@padlet.com https://padlet-uploads.storage.googleapis.com/280180195/3b386da863c1bbf1262cab9f17ce1d40/charles_darwin_9266433_1_402.jpg #6 - Industrial Mechanism tyyoung https://padlet.com/tyyoung/n8qmlt55yfo2/wish/262354600 Point of Explanation:

One thing that I learned from the unit of Evolution, is the “Industrial Mechanism.” The famous example of the mechanism in action, is between the peppered moth and the dark moths. During the industrial revolution, the environment and its organisms had changed because of pollution. Trees for example had darken and dark moths’ population increased dramatically. This is an example of natural selection, the predator that would consume the moths were more likely to consume the peppered variants, because they no longer camouflage to their environment.

Reasoning for Rank:

This is number six on my list, because this is a a small example of evolution and natural selection, there are many more examples and topics of natural selection and evolution that are more compelling.

Another crucial example of evolution in a population, is organisms growing resistant to certain man-made chemicals. Man is considered the top of the hierarchy, and so naturally, the inferior organisms must adapt to survive. One example of evolutionary change against man is bacteria constantly growing resistant to drugs, making the flu shot not as effective. Another example is insects and rodents growing resistant to their chemicals like insecticide and rodenticide. There are many variants of chemicals to kill off this pests that no longer work. 

Reason for Rank: 

This subject is number five on my list, because again, it is a small, but critical supporting observation that supports evolution in action modern day. It is not as crucial as some of the observations made by Darwin as a whole, however.

I learned about Charles Darwin and his observations in the mechanism on the theory of modern day evolution, Charles Darwin is a very significant part of the theory of evolution, without his observations, his theories such as natural selection and descent with modification would not exist as early as it did. Charles Darwin first founded his observation by traveling to the Galapagos Island and observing different kinds of finches with different adapted beaks on different islands.

Reason for Rank:

Charles Darwin is number four on my list, because Darwin contributed a significant amount of information on the theory of evolution. In my opinion however, the theories and subjects he introduced to the world are too important pieces of information to be ranked lower.

Descent with Modification is defined as “When parents have children, the kids descend with similar traits to parents, and they have their own new mutation.” This is a very basic supporting fact to the theory of evolution, and in fact we see Descent with Modification happen daily with organisms such as humans and dogs, and how they look identical to their parent but very different as well. Darwin had said with his observation of Descent with Modification that - “Every species, living or extinct, descended by reproduction from preexisting species and those species change over time.” Where the Descent with Modification gets controversial is when the theory of all species coming from one or a few original kinds of life, in other words, a common ancestor. 

Reason for Rank: 

Descent with Modification is third on my list because it is one of the main observations Darwin made during his observation, Descent with Modification is an easy to observe factor that we witness daily with humans and animals. In my opinion, Descent with Modification only leads to a bigger picture of evolution, and that's why it's ranked number #3.

Evolution is the topic of what we learned about in this unit, originally what I had thought about evolution is that is organisms adapting to their environment over time, but that is only a small part of what evolution is. The definition of evolution is: “Any change in the heritable traits within a population across generations.” Evolution is not an immediate change in most cases, however for some organisms like a family of bacteria, that passed through 3,000 generations in four years. For homosaipens that would take 60,000 years. Two examples of what causes evolution would be Descent with Modification and Natural Selection, two principle ideas Charles Darwin observed. In both scenarios, the species changes over time, and even mutates to adapt to their selected environment. The extent of the evidence for Evolution is also made up of these categories: DNA comparison, Fossil Record, Anatomy comparison and Embryology. All these sources of evidence points to the fact that all things came from a common ancestor, and that change does occur to a species over time.

Reason for Rank:

I rank Evolution number #2 on my list, because Evolution is the core of this unit, and without this theory, we would be ignorant of life on earth. However, I also believe that Darwin's observation of Natural Selection contributed a lot of facts to the study of evolution.

Natural Selection is a big factor to life, adaptation, and the main process behind the study of evolution itself. What I learned about what Natural Selection was, is that it’s the process of how organisms survive and adapt to their environment. Species with the inferior traits compared to others are less likely to repopulate, allowing the species with the favorable traits to reproduce and grow in population. Natural Selection clearly supports both observations of evolution and descent with modification, by supporting the fact change does occur to a population/species over time.

Reasoning for Rank:

I rank Natural Selection #1 on my list, because it is the main process of evolution, and the mechanism of Natural Selection is a very important factor to life, there are countless studies and observations made by Darwin and other scientists that does show how a species adapts to its environment and prospers. It's hard to argue which observation of Darwin's was more important than another, but Natural Selection introduced many explanations and further studies that simply cannot be ignored.
