At the places that people believe that evolution is happening it is often times just an adaptation of an animal to fit its environment better. These things are occurrences that have been observed by people and have been recorded, but evolution is a very large change in an animal over millions of years. No one has observed evolution because what is thought to be evolution is just an adaptation to live better in an animal’s surroundings. The only way for something to be a fact is for it to be observed and then tested to make sure it can be repeated multiple times. Scientists cannot recreate evolution, therefore, it can only be a theory and can only be trusted if a person has faith that it is true.
Planet Earth has experience four eras that include eleven periods and six mass extinctions throughout evolution. The Evolving Planet exhibit at the Field Museum in Chicago, IL describes the evolution of Earth in great detail. The evolution of Earth starts in the Precambrian period and continues to the Cenozoic era, which is still continuing today. Evolution is the idea that living species are descendants of ancestral species that existed from earlier forms of life. All the organisms, rocks, or other products originated from one single cell during the Precambrian period.
“Evolution: a gradual change in the characteristics of a population of animals or plants over successive generations” (Collins English Dictionary, 2011). There has been a vast amount of evidence provided by scientists and paleontologists since Charles Darwin’s expedition to the Galápagos Islands in 1831. Yet there remains the argument against evolution by those who believe in intelligent design, and this argument is still regarded credible by the lack of evidence for evolution in key areas such as the fossil record’s ‘missing links’. The fossil record can be used to observe evolution by natural selection by looking at many layers of rock from different time periods. You can look at the oldest rocks and work upwards to the surface and observe how
Timeline of the Earth As stated in “The Big Bang Theory” theme song, our universe as we know it started because of one big explosion. This explosion was caused by a supernova 13.7 billion years ago. When the big bang happened, all of the elements that were in the star were expelled outward. Around .4 billion years after the big bang, first generation stars started to form, these are the stars that created most of our elements.They were made of period two, three, and four elements. Like every star, these stars ran out of energy and exploded making new elements that are found on our periodic table.
The Fifth chapter was about how science was not really recognized anywhere else but in Britain. There were 3 scientists that were discovering things faster than they could name them so they stop for a while to named them than after they started naming parts of the body. Chapter six “English and Empire” was about how the Britain went on this world to share the language and how they gained more language while touring the world. Chapter seven “The Age of the Dictionary” told the history of the dictionary. It took Dr.Johnson 9 years to put 42 thousand words in his dictionary and years later more and more words were being invented and in 1857 a new dictionary was in the making it took 70 years and 3 people to make it.
Dawkins utilizes the analogy of “history written all over us” in order to showcase the common ancestry that many animals share and how it is shown through various homologous traits. One such example that Dawkins uses is flightless birds, such as ostriches and emus, that never fly in their life but have remnants of wings from their remote flying ancestors (Dawkins 2009). This set of homologous traits in birds is clear evidence of evolution because it showcases how over the years certain species of birds have lost the ability to fly due to certain living conditions. Dawkins also mentions troglobites, which over time have lost the ability to see but still contain “dummy eyes”, in order showcase the fact that evolution is evident in the form of
Scientific definitions at times can be useful but with the topic of race it seems really redundant if everyone has lungs, eyes, hands, etc that function in the same way as every human. The folk definition of race is also redundant because folk definitions always change with every generation, even though it’s the closest definition to social construction. Race has always been a social construction because race did not exist before societies did. The idea of race was completely non-existent if you look at the behaviors of our ancestor species through observing the ways chimpanzees behave we can see that it wasn’t about race it was about “social status; physical fitness, aggressiveness, skill at fighting, ability to form coalitions, intelligence, and other personality traits. Status is either maintained or changed through communication and social interactions, such as physical competition and
A safety bubble has enveloped around much of modern human civilization in which human and animal interactions are either completely controlled or restricted. The few animals that are still a part of modern society have been reduced to the role of pets or zoo animals, and for the first time in history, the animal world is no longer a constant threat to the general population. As modern civilization expands and develops more of the world we inhabit, the animals in our way are either accepted as non-threatening or are exterminated for our own safety. However, Western society has become overconfident, and we have begun to think of our safety as a constant fact of life. Thus, when a non-domesticated animal such as the orca is placed in captivity, a conflict is created between the excitement that comes with such a unique, wild animal and the actual threat that this animal poses.
Paleoanthropologists search for the roots of human physical traits and behavior. They seek to discover how evolution has shaped the potentials, tendencies, and limitations of all people. For many people, paleoanthropology is an exciting scientific field because it investigates the origin, over millions of years, of the universal and defining traits of our species. However, some people find the concept of human evolution troubling because it can seem not to fit with religious and other traditional beliefs about how people, other living things, and the world came to be. Nevertheless, many people have come to reconcile their beliefs with the scientific
Captivity needs to stop because the Orcas don’t live as long, they take the Orcas away from their natural habitat and families, and most of all they need space to swim. One reason that Orcas should not be held captive is because, they don’t live as long. Some people might say that the Orcas at aquariums are very taken care of. But I argue that Orcas do not live as long as they would in
