What Differences And Similarities Did You Notice Between The Trees You Generated?
Question #1
What differences and similarities did you notice between the trees you generated? In particular how did the trees generated with DNA differ than the one you made with physical traits?
- One difference that I observed between the trees generated based on physical traits versus the trees based on DNA were that the trees based on DNA were far more accurate than the trees based on physical traits. The DNA generated trees were based on the physical genetic code, and the similarities between the code, whereas the physical trait generated trees are based more on interpretation of the traits, making them less accurate compared to the DNA trees. On the other hand, one similarity I noticed between the DNA generated tree and the physical trait

This idea highlights that these traits were all evolved from a common ancestor to the mammals representing how the trait has changed overtime, thus illustrated evolution and showed the process. All the traits are seen as “evolutionary significant” because they reflect what the mammal needs most, natural selection and adaptation wise. Most of these animals have evolved to derive their adapted forms of their traits to survive, which is reflected through the phylogeny, thus posing great …show more content…
The reason that I believe they are very closely related is because the physical traits of the two mammals are extremely similar and they both possess the same traits. On top of this, they are both seen to be related in the same clade in every tree presented by the DNA evidence. Therefore, I believe they are related based on the similarities in their DNA and physical traits, given the results I have derived. On the other hand, one of the relationships that I am uncertain with is the rabbit and the deer. Based on the physical trait data, it is seen that the rabbit and the deer are extremely closely related with only one trait discrepancy. When I look at the DNA evidence, the deer and rabbit are somewhat closely related, but not as closely related as the physical trait data entails. Therefore, I am not very certain that they are closely related. I believe the reasoning behind this would be that the physical trait data is more of an interpretation based on analogous and homologous structures, whereas the DNA evidence is far more accurate looking into the genetic relatedness of the structures. This leads me to be uncertain with the relatedness of the deer and the

Sloths Research Paper

They are smarter than me though. Sloths are slow at moving but I am really fast moving. Also a comparison is we are both animals.
The Platypus: The Evolution Of The Duck Bill
797 Words | 4 PagesTwo theories have been suggested to explain the way in which the platypus and other monotremes, e.g. echidna, has evolved in relation to two other mammal groups; the marsupials, e.g. kangaroos, and the placentals, which are animals that use a placenta to aid the rearing of their young. The second theory (Theory A) was first proposed by Gregory (1947), but did not become popular until the 1970s (Hamilton, 1988). His proposal was that at some point between 135 and 65 million years ago, the monotremes and the marsupials separated from the placentals, causing them to evolve in a different way as we know as today. The evidence to support Gregory’s theory is that the reproductive processes of both the marsupials and the monotremes have a remarkable similarity. The embryos of both groups are at some stage encased in a shell during the gestation period.

Fudge not only explains how pets ride the boundary between human and animal to attempt to answer her question, but she also mentions the relationship between humans and pets. Pets are individualized and are loved as “individual creatures”, which makes them different than other animals. Moreover, she explains how our relationships to pets may be the “closest contact many of us have with non-humans”. Because of the way that pets are loved as individuals, she concludes that “a pet is a pet first, an animal

A copy of Chares Darwin’s original sketch of a hypothetical section of a phylogenetic tree with modifications made to show transitional species. Evolutionary theory states that only species which are end points on a branch (i.e. the “end-point species” on Figure 9b) can theoretically exist today.
Arctic Snow Fox Evolution
774 Words | 4 PagesStructure: Leg Function: To be able to move Evolutionary Change: Bottleneck Effect Explantation: Due to the bottleneck effect the forest fox will lose its genetic variation between leg size because the forest foxes with the shorter legs have a lower chance of survival because the ones with the longer legs will end up being more athletic. Also due to co-evolution with its predators like a tiger, the fox will grow legs to be able to outrun the tiger, but the tiger will also evolve to have longer legs to be able to catch the fox. This is macroevolution because all land mammals will need to have longer legs because the faster they
Compare And Contrast The Jumping Tree And The Ravine
247 Words | 1 PagesThere are two stories I’ve read, “The Jumping Tree” and “The Ravine”. Both stories involved jumping from a dangerous height. The two main characters, Vinny and Rey, had to make a decision. I think Vinny made the best decision because he didn’t jump, unlike Rey. One reason I think Vinny made the best decision is because he was brave.

As we are continually in the process of discovering the history of human beings, there are many questions surrounding this topic. One very interesting question is why ancient ancestors of homo-sapiens evolved to walk upright like we do today. An apes’ DNA is astonishingly similar to that of a humans, (97% the same) and yet, our bones’ shapes and structure are very different.
Differences: Similarities Between Humans And Monkeys
754 Words | 4 PagesAlthough humans and monkeys are different, they are also very similar. They are probably more similar than they are different. Despite their differences, it is often said that humans were once apes, a type of monkey that within the years slowly evolved to adapt to their climate and environment. With this evolution came a lot of changes, especially physical ones. While it is not known if this is true or not, it is true that humans and monkeys are closely related.
