Homology & Analogy for Thought...

HOMOLOGOUS:

A. The two species I am identifying as homologous are, the great ape specifically a gorilla  and human. The great ape also known as a Hominidae can be located in Africa or Asia and mostly live in forest area. While the Human or Homo Sapiens vary all around the world and are great contributors to our society.

B. The homologous trait that the great ape gorilla and the human both carry is the Pelvic bone.  The main function for this trait is to be able to stand upright.  For the Gorilla the other uses for the pelvic bone are to move on all four soles of their feet, and be able to sit upright. The pelvic bone however for the Human is for walking upright vs slouched as the gorilla would be, the human body is supported by the pelvic bone which allows us to move forward with our legs and have motion up and down. The trait differs in position in some cases but also provides upper and lower body support.

C. The common ancestor for these two species is the Australopithecus Afarensis, also known as a first found hominin which dates back to 3.2 million years ago. Lucy a well known skeleton found then was the first Australopithecus afarensis who began the pelvic bone structure. For this species the pelvic bone was much relied on due to the greater height this type was. It is certain that this species carries this trait because it too was proven to stand and walk upright.

ANALOGOUS:

1. The two analogous species I am identifying is a Blue Whale and Bat. The whale known to be one of the largest animals is a sea mammal who swims through Pacific, Northern, and Atlantic oceans. The bat or scientifically known as Chiropteran is also a mammal who flies and uses the amazing echolocation to communicate within each other. 

2. 

   Forelimb of Whale & Bat

   The Trait that these two species have is an appendage called the forelimb, which contains the Ulna, Carpals, Radius. The Blue Whale uses this appendage in their fins to helps them swim through the ocean, and to catch pray, two very important tasks with this trait. The Bat uses theirs to fly and use their wings much like hands to preform things such as climbing and shading themselves or catching prey. They both use their appendage to stay fed, have motion, and fight off any attacks.

3. The common ancestor most likely could have had this trait because it is a needed body part that helps with mostly all structures to function. These traits are analogous because the whale and bat do not share a common ancestor and adapt to their environments, ocean vs sea well.

Historical Influence of Darwin's Natural Selection Theory:Jean Baptise Lamarck

1. The individual that I have chosen to have influenced Charles Darwin's Natural Selection theory the most would be Charles Lyell who carried his belief in uniformitarianism: which is "the theory that changes in the earth's crust during geological history have resulted from the action of continuous and uniform processes.". He was the founder of modern geology who contributed to Darwin's Natural selection theory by proving catastrophism to be wrong which further proved his theory to be correct and giving more evidence that natural selection is true with is findings.

2. The contribution that Lyell had made positively to the scientific community is that uniformitarianism is logical and supports Darwin's natural selection. Darwin believed in constant evolution whereas Lyell ruled out what would have falsified his theory of consistency from George Cuvier who argued that catastrophism (the theory that changes in the earth's crust during geological history have resulted chiefly from sudden violent and unusual events) would counter his belief of natural selection and the evolution of species. Lyell contributed to proving Darwin's theory when he proved that the Earth would not be able to "withstand multiple catastrophic events" resulting in loss of regions, species, etc. This helped the process of Natural selection be validated.

3. The point that "Organisms with better access to resources will be more successful in their reproductive efforts," traces back to the geological process of uniformitarianism that Lyell implemented. This shows that the geology of an organism in an area will evolve well with consistent access to what they need.

4. Darwin could have continued to prove natural selection to be true without Lyell's input because he had already obtained other evidence, I believe Lyell's contribution was extra evidence to strengthen but not necessary to complete his process.

5. The attitude of the church affected Darwin's Theory by giving him hesitation of going against his families religious views. Yet his work was threatened and almost credited to someone else so he had to publish his work before he could be discredited for all his years of work.

Anthropology Q1

If you were stranded on a desert island what two items you would take with you and why?

If I were stranded on a desert island the two items I would bring would be a fire starter, and food. The fire starter can provide me with a warm environment on a cold night, while the food will keep me alive and enable me from starving.
