There are so many mysteries that remain unsolved even until now; one of them and probably the most popular is how life started and how organisms were ‘created’. There are two theories that stand out the most; evolution and intelligent design. While evolution explains how organisms had developed from simple forms billions years ago through a process called natural selection, intelligent design states that nature is too complex to happened by a random process like evolution by natural selection, thus there must be an “intelligent agent” that is responsible for the creation of the universe. William Paley, in his book Natural Theology: or, Evidence of the Existence and Attributes of the Deity explained intelligent design by comparing the complexity …show more content…
However the design of the eye is not perfect; human eye has a blind spot which is not sensitive to light and they have to move the eye in order to see accurately because human only have only one fovea in each eye with high resolution thus limiting human’s vision. Humans have delicate a lens that can easily change shape causing eye problems like myopia. Furthermore, the lens’s nutrient source comes from the fluid surrounding it, this mechanism cause problems for the inner cells because it cannot get enough nutrients, and because of this our lens become less flexible as we age. Apart from the eye, another flaw of design is human upright position. While most mammals walk on four limbs, human walk on two limbs (bipedal) and have an upright position, allowing human to use their hands as tools but also resulting in some disadvantages such as back pains due to human’s curved spines as the result of enduring a lot of pressure to maintain upright position and balance, knee pains because human concentrated all their weight on their legs, and increases the risk of deaths from giving birth in females and their baby due to human female’s narrow birth …show more content…
However, humans have practiced selective breeding and create varieties of multi-cellular organisms by changing their morphology. Pomeranian for example; in the late 1800s Pomeranians average weight were 14 kilograms and are all white, but human selectively bred them and modern Pomeranians now only weight about 2.5 kilograms and come in varieties of colours . In nature, natural selection happens as well but unlike in selective selection it does not have an executioner who decides which characteristics are bred. In natural selection, the ones with characteristics that are favoured for survival get to live and pass on their genes, but the ones who do not, died out along with their characteristic because of their inability to compete. This could lead to extinction of that characteristic because it did not get passed on. On the other hand, the ones who survive pass on their characteristic to the next generation leading to change of morphology or behaviour of the species. The Galapagos finch birds is an example of selection in nature, Peter and Rosemary Grant observed the flinches in Galapagos Island and found out that there are 13 finch species with different behaviours and characteristic, after a drought in 1977, the average beak and body size of the bird increase, even in 1978 when the weather went back to normal, the size remains. The drought causes the smaller size birds with
Biology, the study of life and living organisms, is complex and encompasses a multitude of theories and ideas. In AP Biology, the first unit covered was evolution. Chapters 29, 31, 39, 40, 41, 42, and 43 in the textbook, Campbell’s Biology in Focus, not only discusses the four main ideas of biology: evolution, energy, information, and systems, but it also gives examples of each in order to help guide the reader’s understanding of the concepts. The first big idea of AP Biology is: “the process of evolution drives the diversity and unity of life.” Chapter 39 in the textbook encompasses this main idea through discussing natural selection and genetic diversity.
Creation From Science to Religion, the questions with the most varied answers are “How did life come to exist?” and “How did the universe come into existence?” In Genesis, it states, “In the beginning God created the heavens and the Earth” straightforwardly explaining how the universe came into existence in the most basic form, God created it. (Genesis 1:1)
The size of the seeds that are plentiful in a certain year, determine whether small beaked birds or large beaked birds make up a bigger part of the population. In other words, if smaller seeds are more plentiful, the smaller beaked birds will make up a greater percentage of the population, because the species adapted to the environment around them. As a matter of fact, these birds live on an island called Daphne Major, which is known as a laboratory of evolution. This video explored Darwin’s theories, while also highlighting the beauty of an area in the world, where unique animals are located. It is also explained in the video, that all of the animals on the different islands started from their own ancestors and eventually became many different species by adapting to the environments over time.
One characteristic that many people believe it distinguishes Homo sapiens from other apes like chimpanzees or bonobos is our capacity for intelligence. Another distinguishing trait is the human capacity for a full time bipedalism. So It is no accident that many anthropologists have recognized a correlation between human bipedalism and intelligence. Carl Ernst von bear once remarked “Upright posture is only the consequence of higher development of the brain”. It is hypothesized that bipedalism allowed hominins to use their hands for stone tools and more efficient forging, considering that the brain is the most metabolically taxing organ in the body, in humans at least, it takes about twenty percent of our energy consumption.
The scope of Darwinism is centered on the basis that evolution is brought about by the distinctive survival of only the superior individuals in a general pool. As a result of this, different strata or classes are mandatory in a species. With time, the space between the different strata is great enough to the extent that the superior class is granted advantages over the inferior class. This changes brought about by the Darwinism movement brought about the rise of a new movement called the Eugenics Movement and Social Darwinism.
Grant, this book is a complete set piece based on Darwin’s work and theory about finches, the book has in depth knowledge about the finch, its behaviour, physical structure, habitat, lifespan, evolution and physiology. This book is very relevant has it has enough information to answer the question “What is the relationship between Galapagos finches and South American finches?” The book was published 1999 making not recent but still relevant due to the in depth information it contains. The book has only two references to previous books of the same subject, referencing is done mainly in the form of citation, the author cites at many points where he received the quote from. The book is not peer
After some time, those differences that make the organism with more ability, will become fixed in the entire population, while those that make it less so will be eliminated. This mechanism is called natural
In Introduction to Evolutionary Biology by Chris Colby, the author’s purpose was to explain the basics of the theory of evolution and correct the many of the misconceptions. The main parts are the meaning of evolution and the misconceptions. The meaning of evolution according to Colby is a change in the gene pool of a population over time. The first misconception is that evolution can occur without morphological change and morphological change can occur without evolution. The second misconception of evolution is that natural selection and evolution are the same thing.
If something is created, surely it has a creator; nothing makes itself. According to Lewis Vaughn, author of “Philosophy Here and Now” William Paley created the Teleological argument (Vaughn, 58). Paley argues that “the world resembles a watch in that it too looks as if it were designed by some intelligent being; therefore, the universe was probably also created by an intelligent designer-in other words by God” (Vaughn, 58-59). We know from common knowledge that if we see a car, a home, or something as simple as a stack of pancakes, someone made it; it did not make itself. Therefore, it is not likely that the world evolved as the naturalist Charles Darwin implied, or that there was a big boom and then suddenly earth was created and fully stocked for human and animal survival as George Lemaître suggested.
In directional selection, one extreme trait is favored over the mean trait or other extreme trait; and this occurs in environments that have undergone changes over time. Changes in terms of climate, weather and food availability are the driving forces for this type of natural selection. If shown on a graph, the population bell curve shifts either farther left or farther right, indicating that one trait, is favored over another for a species. An example of this type of natural selection is the beak length of the Galapagos finches, which changed through time due to changes in food availability. Those with larger and deeper beaks survived the scarcity of insects since they were able to crack seeds.
Origins Reflection There are many different perspectives, and theories on how the universe and human life came about. One perspective in particular really trumps the knowledge of us as human beings. The Christian worldview comes down to faith. According to the textbook, faith “is the process of committing to particular presuppositions; the act of trusting in Jesus Christ to define oneself, which constitutes a transformation of a person 's spirit from selfishness to selflessness. ”(Waddell, 2014)
Natural selection is one of the four mechanisms of evolution. However, human beings are able to produce their own selected species by artificial selection. Scientists select desirable traits for organisms, rather than leaving organisms to evolve by themselves. Dog domestication and breeding are works of artificial selection. All dogs have a common ancestor of the grey wolf but recent researches have shown that the dogs are originated from different subspecies of grey wolves.
The authors provided no precise explanation for how these organisms formed, or how the organisms knew what to do once formed. Though there are many points of uncertainty, it is a valid theory for the beginning of life in their eyes.
Charles Darwin was the first to really lay out a ultimate theory for how humans (and all other life) came to be. Up until then, all alternatives to the globally accepted Creationism were unclear concepts and ideas. Evolution is actually an addition of natural selection, the theory that states that the strongest will survive, while the weakest will die out. Whenever a change happens to the environment, animals who are unable to change and adapt themselves will die out. The ones that can change will survive, and those that excel at adaptation, such as humans, will thrive and eventually dominate their environment.
EVOLUTION The evolution model explains the living world through the theory that it is approximately 3 billion years and that life spontaneously appeared and has been evolving and into more complex organisms through mutations and the process of natural selection. This theory originate from Charles Darwin 's. Timelines CREATIONISM TIMELINE 1.Derivations This particular creationist view of the origins of the earth is derived from The Torah or commonly known as the Pentateuch which is the Judaism holy book.
