2. Therefore, organisms could change their bodies during their lifetime, for both their offsprings or themselves.
3. Since if human grows unchecked, there would be no enough living space, so natural selection is necessary.
4. Artificial selection is to let characteristics of species to be selected by humans.
5. Differences between fitness and adaptation is to fit in environment or not.
6. Natural selection only enabling useful species to survive and reproduce; the process of NS is Struggling for Existence -- Variation and Adaptation -- Survival for the Fittest -- NS. Therefore, there is no perfect species.
7. All species are descended from ancient common ancestors, which proves the existence of natural selection.]]> 2020-08-28 15:25:36 UTC https://padlet.com/ksmith1088/agey1kxfym26or2w/wish/705227657 22lucasl5 https://padlet.com/ksmith1088/agey1kxfym26or2w/wish/705230940 I found it interesting how Darwin used multiple ideas that had existed previously to support his theory of evolution, from the idea of “deep earth” to explain canyons and rock formations to the reasons why overcrowding was prevalent in cities like London.]]> 2020-08-28 15:26:37 UTC https://padlet.com/ksmith1088/agey1kxfym26or2w/wish/705230940 22lizziep https://padlet.com/ksmith1088/agey1kxfym26or2w/wish/705600070 There's an important distinction between Lamarck's ideas and Darwin's theory that helped clarify questions I've had. Lamarck thought that an animal could acquire a trait in its lifetime (such as longer legs) and pass that trait onto its offspring. This does not make sense because animals cannot pass on physical features they've aquired; they can only pass on traits that are in their DNA. Darwin refined this by explaining that the variations of animals exist in the first place, and this is vital for evolution to occur. It makes sense that species with the right variations for their environment would thrive, reproduce, and out-live other animals with less helpful characteristics. How long does it take to see this play out? How could all animals eventually descend from common ancestors in Darwin's "tree thinking?"]]> 2020-08-28 17:17:02 UTC https://padlet.com/ksmith1088/agey1kxfym26or2w/wish/705600070 22gracies https://padlet.com/ksmith1088/agey1kxfym26or2w/wish/705641892 Even though 16.2is certainly not all about the idea of artificial selection, I thought it was a very interesting subject. Especially when the book tells us Darwin had no idea of hereditary similarities, I think it’s so cool how he, and many others, were able to piece little pieces of evidence together, like which plants grow the largest and are abundant with fruit, which cows produce more milk, and take advantage of that. We often associate “Survival of the Fittest” and “Natural selection” with animals in the wild, them having to hunt for food or be hunted, having to take care of themselves, I can think of it now in relation to my life, but now when I think of that phrase I think of people just wanting to be better and do better than everyone else, not really that in a sense it’s really survival, for animals and some humans (Sorry tangent). One question I have is, does/did Darwin believe that all animals come from a single fish ancestor (read last of 16.3).]]> 2020-08-28 17:30:38 UTC https://padlet.com/ksmith1088/agey1kxfym26or2w/wish/705641892 22carolinem1 https://padlet.com/ksmith1088/agey1kxfym26or2w/wish/705973951 I found reading Darwin's theory of evolution very fascinating. The more that I read about natural selection in animals, the more I wondered to what extent "survival of the fittest" applies to humans also. Especially in this day and age when people with medical differences are able to have more support from the medical community and societal support to have children, therefore passing on their genes, I think that this is incredibly applicable. I also was intrigued by how the fact that the earth was not relatively new was a concept that was still developing when Darwin was publishing his research. ]]> 2020-08-28 19:27:34 UTC https://padlet.com/ksmith1088/agey1kxfym26or2w/wish/705973951 22emmal https://padlet.com/ksmith1088/agey1kxfym26or2w/wish/706037941 I thought it was really interesting to see the process Darwin went through to formulate is theory of evolution, especially his concept of artificial selection. I find this concept fascinating, and it makes me wonder what plants, birds, etc.. came from this process to be what they are today? I also found it very interesting that during Darwin's time, when people thought of the earth as only a few thousand years old, people like Hutton & Lyell were using science to prove that it was actually much older, since the idea of the earth only being a few thousand years old was primarily taken from a biblical perspective. ]]> 2020-08-28 19:56:45 UTC https://padlet.com/ksmith1088/agey1kxfym26or2w/wish/706037941 22ellan https://padlet.com/ksmith1088/agey1kxfym26or2w/wish/706646481 I enjoyed learning about all the other scientists who influenced Darwin’s work. It was interesting that Darwin was reading Lyell’s work while on the Beagle. This enabled him to recognize the significance of finding marine fossils in the mountains. I hadn’t realized that Darwin was able to develop his theories because of the work of James Hutton on deep time, Charles Lyell on uniformitarianism, and Jean Baptiste Lamarck on acquired characteristics.]]> 2020-08-29 15:25:55 UTC https://padlet.com/ksmith1088/agey1kxfym26or2w/wish/706646481 22jacobh https://padlet.com/ksmith1088/agey1kxfym26or2w/wish/706892237 I was surprised when I found out that Darwin used the work of many different scientists to create his work. Originally, I had thought that Darwin had created a completely new theory. In reality, it seems, Darwin mostly combined the work of others into a definitive work. Of course, he had his own ideas that he found himself, but he wouldn't have had those ideas if he hadn't studied the work of others. An example of that is how he linked the earthquake with Hutton's discoveries.]]> 2020-08-30 00:22:03 UTC https://padlet.com/ksmith1088/agey1kxfym26or2w/wish/706892237 22emilyf1 https://padlet.com/ksmith1088/agey1kxfym26or2w/wish/706912296 I found Darwin's idea of descent with modification very interesting. I had never thought that species descended from common ancestors as Darwin suggested. This idea of common descent reinforces Darwin's theory about deep time. Descent with modification occurred during deep time because it allowed enough time for natural selection to take place. In a way, the idea of descent with modification seems to put all of Darwin's ideas together, including deep time, survival of the fittest, and natural selection. ]]> 2020-08-30 01:15:31 UTC https://padlet.com/ksmith1088/agey1kxfym26or2w/wish/706912296 22averyh https://padlet.com/ksmith1088/agey1kxfym26or2w/wish/706966794 I personally though Lamarack’s ideas were super cool. Although not all of them turned out to be correct, his discovery that not all organisms were fixed was insightful and led many others to expand that idea into evolution. He talks about acquired characteristics, which honestly I didn’t know much about! I find it fascinating that the bird he specifically used in his example acquired longer legs because of its constant wading in high waters. Though we discovered these characteristics can’t be passed down through reproduction, it led us to find out about artificial selection.

How come of all the people in the Beagle’s voyage, only Darwin tried to figure out what they were seeing? Evolution does not go in a set direction, but rather in multiple directions, with some being more successful in others. There are multiple answers to the question of how to evolve to survive in a certain environment.]]> 2020-08-30 15:48:32 UTC https://padlet.com/ksmith1088/agey1kxfym26or2w/wish/707332833 22kates2 https://padlet.com/ksmith1088/agey1kxfym26or2w/wish/707863324 I found it interesting that Darwin didn’t release any of his ideas with the world for a very long time. He had gathered all of his data pretty early but didn’t want to share until he was sure he could prove it. I also found it interesting that he used the works and ideas of many different scientists to help pad some of his theories. I had always heard about natural selection and we learned about it pretty thoroughly last year,  but I didn’t know a lot of the details on how Darwin came up with that idea and I think it was really cool to see that he realized that animals were living longer because of their adaptations but that didn’t mean they had become “perfect”.]]> 2020-08-31 03:06:19 UTC https://padlet.com/ksmith1088/agey1kxfym26or2w/wish/707863324 22yujianf https://padlet.com/ksmith1088/agey1kxfym26or2w/wish/708445211 I think Darwin is brilliant and patient. He was influenced by lots of other pear of scientists who has founded work on Geology and biology and got inspiration from artificial selection. I am especially impressed when I read that he didn't publish his idea until 20 years later. It must be an huge torture to burden the truth under heart among criticisms to seek for the best way to convince people. Combining with a mass of evidence he collected for 20 years, he finally to push forward is publication on the theory of evolution.
If the biological diversity on earth is not limited only on earth but also from the influence of outer space chemicals and viruses, will Evolution still be strong enough to explain all history of life?]]> 2020-08-31 12:10:26 UTC https://padlet.com/ksmith1088/agey1kxfym26or2w/wish/708445211 22jeffryl https://padlet.com/ksmith1088/agey1kxfym26or2w/wish/708795764 I found it interesting to read just how much work of other scientist had gone into Darwin’s theory of Evolution. To hear that Hutton, Lamarck, Malthus and many others had spent their lives researching similar things to Darwin giving Darwin the knowledge to make his theory known almost makes me a little sad that those names are not very well known compared to Darwin’s name. ]]> 2020-08-31 14:10:08 UTC https://padlet.com/ksmith1088/agey1kxfym26or2w/wish/708795764 22sophias1 https://padlet.com/ksmith1088/agey1kxfym26or2w/wish/708918538 I thought these chapters did a really good job of integrating in Darwin's work and theories into the time period in which they took place in and their effects on today by using the work and theories of other scientists from which Darwin might have based his thinking from. I think there is a lot to be learned from Darwin and his methods of scientific thinking, especially the careful and intentional nature of his gathering of data. ]]> 2020-08-31 14:40:46 UTC https://padlet.com/ksmith1088/agey1kxfym26or2w/wish/708918538 22wenboz https://padlet.com/ksmith1088/agey1kxfym26or2w/wish/710525594 In fact, I really surprised that there are many supporters on Darwin and his own theory. In the past, it is really hard to find a lot of supporters when a theory was firstly found. The main story would be "everyone doubt about Darwin's new theory, and he used 50 or even 60 years to prove that only by himself..." That's a true story. However, in only several years, the age testing results on fossils, new ideas about natural selection, and ideas about evolution & body changes has been coming out, in order to support Darwin. It is just like a fairy tale. It looks unusual. Especially for Malthus' idea, it is pretty cool since it could explain that for any species, why most newborn children are died, and why do pandemic occurs periodically, while the world is in peace and growing circumstances. So, how to comment on those scientists... they are so genius and imaginated.
Question: Darwin easily break the theory from the past 2,000 years go; would their be any scientists in the future break Darwin's theory just a piece of cake?]]> 2020-09-01 01:31:15 UTC https://padlet.com/ksmith1088/agey1kxfym26or2w/wish/710525594
