Analogy/Homology Blog Post Week 3

HOMOLOGOUS
1a. Two species that possess the homologous trait are a human and a dolphin. Both seem to have some sort of arm or limb in order to get things and get places. A human has an arm living on land and a dolphin has a fin living underwater.

1b. Humans and dolphins are different in many ways. Dolphins live in the ocean, swimming around in water with FINS while humans live on ground and do many things like drive and write with an ARM. Humans and dolphins eat differently as well. We can eat so many things, while dolphins are limited to food like fish. A humans hand looks more defined and easily read with 5 fingers to look as if they easily grab things,while a fin looks like a flat fin they use to swim, but in reality it is easy for them to use in so many ways. The bones of the human and dolphin (image below) are shaped differently, with an arm looking straight and a fin looking more ovalish. Dolphins use a fin to communicate while we use our voices and use hands to handle with things, like driving and dolphins can swim with it, as a mean of transportation. In term of the bone structure, humans have a clavicle and a right scapula for example and a dolphin has a rudimentary ulna that the human doesn't. Also, They do share a bone placement like a thumb.
1c.The general ancestor of a human and dolphin can possibly be the development of the bone structure of a human's arm and a dolphin's fin, as they are both mammals and must have been shared by a common ancestor, both having different structures and functions. They both need their arm and fin to be able to do things and without it they wouldn't be able to do as many things.
1d.
ANALOGOUS
2a. Two examples of analogous species are a butterfly and a bird wings. Butterflies have more various and colorful wings, antennas, light weight insect. A bird has a beak, feathers, and legs for example, Both share wings in order to fly.
2b. Both share many similarities and the main similarity is both a butterfly and bird have wings. they use these wings to fly to get from place to place, to get food for example and these wings are make them who they are. Both have unique sets of wings that connect to parts of their main bodies. An example of the bird can be a dove and an example of a butterfly is the monarch butterfly.
2c. A common ancestor cannot be seen in both a butterfly and a bird because no ancestor of theirs had wings. It may have possibly been through a reptile and did not share these similarities millions of years ago.

Charles Lyell

1. Charles Lyell had the most positive influence over Darwin's development of his theory of natural selection.
2. http://www.pbs.org/wgbh/evolution/library/02/4/l_024_01.html
http://www.famousscientists.org/charles-lyell/
Charles Lyell wrote Principles of Geology in 1830, including the main idea in the text "that evidence of forces of geological change that have been shaping Earth for millennia is observable today," according to pbs.org. Principles of Geology was known as "a landmark work in geology that explores James Hutton’s doctrine of uniformitarian," as said by famousscientists.com. Lyell was one of the most famous British geologist and lawyer. Lyell stated that the formation of the Earth's crust was located through countless tiny changes happening of may time periods.
3. Lyell had many views on how the Earth was created which probably sparked Darwin's imagination and formed his beliefs. Charles Lyell gone against any common idea said by any Christians or geologists.  According to Lyell, he believed that any "forces molding the planet today have operated continuously throughout its history," as stated in pbs.org.  Lyell thought that every single living creature was born in a niche in which it was formed. Lyell greatly influenced Darwin with the idea that species become born and eventually die, like Lyell's beliefs, there is a "shifting and rising and falling of land," and that's how Darwin came up with  "reproduction, inheritance and competition" on our diverse home, Earth (pbs.org).
4. Darwin could not have developed his theory without Charles Lyell. Lyell had many opinions in his work that must have had something strike out to Darwin. They both share a common theme that all species must be born and must die, including survival of the fittest, something we do as a whole. We adapt to our surroundings that we were born in. This is how we can go back in time to learn and evolve from that experience, coming from generation to generation. Darwin more so added to Lyell's main point which backed up Lyell's main objective.
5. The attitude of the church made Darwin doubt himself and his work. Religion and evolution do not go together and cannot be mixed according to the church, they believed Darwin's work had nothing to do with religion and that simply did not please them. They seem to fight over which one is true. Ideally, no one really knows unless you experience something of that nature.

PRACTICE POST: 2 Items

If i was stranded on a desert island the two items i would bring, would be:
    1. Tent
    2. Food
I would bring a tent and food because i would have somewhere to sleep or stay while i am stranded on the island. I would already bring food because i would need something to survive on and the island wont have food from where i live. there isn't a market on an island! I would have these things because this island will not have a tent or food when i am here, unless i would have to make it, but i need that time to write an SOS sign to get saved!
