4 Lines Of Evidence 10/15/17

Summary:
Throughout this unit of Evolution, we've determined that all living things have a common ancestor and that natural processes can determine who lives and who dies, but what evidence is there to back up this "theory". The Four Lines Of Evolution include comparative anatomy, embryology, fossil records, and DNA.Comparative anatomy is analyzing the physical similarities and differences between organisms. Embryology is studying how creatures develop before being born and noting comparisons. Next, there is the fossil record in which you compare and contrast animals that are living today with fossils of animals who lived in the past to bridge the gap and help figure out which animals resemble each other more. Lastly, you can use DNA to see which animals are closely related to one another. Diving a bit deeper into the fossil records, we can see how different organisms of the past acted and see how that applies to animals and plants that are still alive today. For example, curled up trilobite fossils can show that they were protecting themselves in the same way pill bugs do currently. Another example of this would be if someone were to find aquatic animal fossils in the desert. This would show that this land used to contain a body of water and was inhabited by other marine animals and plants.
S&EP-Using Models(Poster):
Like mentioned above, there are four lines of evidence and one of them is the fossil record. To represent and understand the fossil record works we made a poster of the "Adventurian" organism. We went as far back as the Cambrian Era to show the organism as it first was which looked like a fish that lived in water. Although this may be the case, by the end of our model one branch of the "Adventurian" had grown legs and moved on to be a land animal. After a few Eras, during the Devonian time, the "Adventurian" spouted into two different families, the whiteheads, and grey heads. The grey heads went on to develop legs whereas the white heads remained a fish-like creature. This definitely showed evolution, especially in looking at its morphology. For example, the color of the organism changed and by the end, there were multiple types of the same organism with different body shapes. This showed how fossil records could help us see how different animals are related because if we hadn't traced back past the Devonian Era we would have known that the two branches of the "Adventurian" were actually related.
XCC-Patterns:
Evolution itself is a pattern that you can see through multiple forms including living things. While beginning to study the four lines of evidence, we implemented what we learned into the evolution of video game consoles. The first line of evidence, comparative anatomy showed that mostly all video game consoles came with a controller and were the same box-like shape. Next, we applied the second line of evidence, embryology. In the terms of video consoles, we can see embryology in the fact that they all have the same base parts such as a motherboard. As for the fossil record, some I remembered how we have an X-Box 1 at home. The structure is roughly the same (with some differences) and they work in somewhat the same way, as well. DNA is like the code in your body, so this comparison was easy to make. The similar DNA of video game consoles is that they all have the code and it is probably similar to one another because they have the same function. All in all, this pattern I saw through the four lines of evidence applied to video game consoles giving me a deeper understanding of the topic.

This week I was a mutant, to be more specific a creator because I offered up whatever I could do to complete our fossils record poster on time.
