Charles Darwin Essay

In February of 2002 primatologist Jane Goodall delivered a speech titled “What Separates us From Chimpanzees.” Her purpose is to address the topic as a question, providing specific evidence, and call us to action. Goodall’s primary audience are those who were viewing the TED Talk at the time it occurred. This included people who are both very intelligent in the field of zoology, and those who are naive. Goodall taps the interests of those well educated in a field like hers, but at the same…

Genetic drift is a mechanism of evolution that occurs by random chance rather than natural selection. In genetic drift, a population experiences a change in the frequency of a given allele, prompted by random luck rather than a need for adaptation. This differs from natural selection, in which allelic frequency is altered based on the fittest genes surviving to reproduce and the weaker genes dying off. Genetic drift tends to be a phenomenon amongst smaller populations, while natural selection…

Mutations are changes in the genetic code which is the only way through which new genetic material and variations can be obtained. Mutations further include chromosomal mutations which is necessary for various variations. Genetic Drift can be defined as how the changes that occur randomly in the frequency of alleles which impact populations of many species. These also lead to effects such as bottle neck and founders effect. Natural Selection revolves around the concept of fitness which…

New Take on Tropical Songbirds’ Alternative Lifestyles A breakthrough study published on Friday in the journal Science uses life history theory to explain why tropical songbirds typically raise fewer chicks than temperate songbirds. What’s life history theory? Life history theory seeks to explain the ways in which natural selection works to determine a given organism’s anatomy and behaviors. Life history theory suggests that reproductive tendencies, or “life history strategies,” are part of a…

Dr. Harvey Wiley is known as the pioneer of consumer activism. He was the first at the Food and Drug Administration, where he became known as the "Father of the Pure Food and Drugs Act". Wiley was born in 1844 on a frontier farm in Indiana. He spent his adolescence years planting and harvesting crops. His father was a humble school teacher who believed that all children should have basic education. He was one of the few in his family to go to college. He excelled in medicine and received a…

Have you ever wondered where we came from or how we got here? Some believe we came about through the single cell theory or evolution, but others believe life was created by some higher being that they call god. The teleological argument know also as the argument from design. The argument is used by theists to persuade the existence of god to agnostics and atheists. It states that god or some intelligent being created the universe or life on earth and keeps it in balance. It tells that an object…

Sauropoda For my dinosaur, I chose to research the Sauropoda. According to scientists, the Sauropoda was thought to be alive during the late Triassic period, which was roughly 65 million years ago. As a result of scientist’s theories, they believe that the Sauropoda was killed of at some point during the cretaceous period. Sauropoda means,”Lizard footed”. Because scientist have found more and more information about these dinosaurs, they are still coming up with different theories. The…

Altruism in Elephants: Empathy and Higher Cognitive Ability It is generally thought that altruism is a behavior only displayed by simplistic creatures, such as ants or honeybees, which do not possess the cognitive ability to evaluate short or long-term reciprocal benefits. Very few mammal species have been observed to display truly altruistic behaviors. Dolphins and elephants, as well as the great apes, are examples of the few mammalian species which commonly display altruistic behavior,…

Frederick Sanger was born to Cicely Sanger and Frederick Sanger on August 13, 1918 in Rendcomb, England. At age 18 Sanger went against his family and decided to become a scientist instead of a doctor like his father (Jeffers, 2017). He attended St. John’s College in Cambridge and majored in biochemistry. After he graduated he married Margaret Joan Howe at age 22 and had three children with her. He later came back and worked with Albert Neuberger in order to study the metabolism of…

All animals belong to the supergroup Unikonta. Since these animals are found in almost every environment on earth, it has become possible to study their characteristics and construct evolutionary relationships, noting morphological and molecular similarities and differences. The relationships between the most primitive of animals were determined by the morphological traits of symmetry, tissues, body cavity, embryological development, and molecular evidence. [1] Symmetry and tissues are major…
