Humans are the only species that have acquired the ability to combat evolution. Our ancestors relied solely on genetic adaptations to survive. This principle is defined by natural selection. Today, humans are changing the world so quickly that natural selection cannot keep up. Humanity is able to achieve this by controlling environments and aiding “bad” mutations in circulating throughout the genetic pool. Humans are learning how to control environments before natural selection can change them

Charles John Huffam Dickens was born on February 7, 1812. Although Charles Dickens was not born during the time of the French Revolution, which is the time period his book, A Tale of Two Cites takes place in. He still infuses pieces of his life’s story into the characters and plot of A Tale of Two Cites. He shows similarities between himself and Jerry Cruncher. Dickens shows a few similarities between Dr. Manette and his own father. He also explains in detail the lives of the poor and the rich, in

At the beginning of the 20th century, geneticists began to understand the laws of heredity and the origin of new variability from the mutation. However, since evolution is a process that develops over time, it was necessary to investigate how the variability present in a population behaved across generations. Thomas Hunt Morgan, who was a geneticist and embryologist of that era, was one of the first to explain the genetics based on the laws of Gregor Mendel, who was known as the creator of the science

Using your sociological imagination gives you an insight of society as Herbert Spencer and Emile Durkheim have their own views as sociologist. Spencer believed in the theory of evolution and applied it to society believing that it isn’t necessary to change society because it will change on its own. His concept of Social Darwinism suggested that the upper class are meant to thrive and move forward and the weak are meant to die out, becoming extinct. Humans as animals compete to survive which he referred

Blending Inheritance is a concept that many people believed. The concept of Blending Inheritance is that an offspring gets 50% of its traits from one parent and the other 50% from the other parent. An example is a yellow butterfly and a rare blue butterfly mating to making a green butterfly. The green butterfly will mate with a common yellow butterfly and make the blue butterfly go extinct. This concept was disproven through more valid concepts like Incomplete Dominance, Co-Dominance, Epistasis,

Hummingbirds are the second most diverse family of birds with about 340 known species. These little birds can travel vast distances; around 30 percent of hummingbird species migrate between the USA, Canada and Mexico. We do not know how migration is triggered. They are known to only reside in the western hemisphere. Hummingbirds have received relatively little attention from a conservation aspect, especially considering their commonplace and popularity with people. Scientists dilemma: unlike many

This essay will examine the lives of Michel Sarrazin, Thomas Wright, David Douglas, Archibald Menzies, and James Finley Weir Johnston, who were all scientists. The themes by which these individuals will be compared are country of origin, branch of scientific study, number of children, and lifespan. In this discussion, five sources will be the biography of each explorer, as found in the Dictionary of Canadian Biography Online, and a sixth source will be J.M. Bumsted's book, A History of the Canadian

Hume criticism of the teleological argument questions the strength of Paley’s watchmaker analogy (although it must be noted that Hume’s criticism came 23 years before Paley made his argument) by debating whether the universe and watches are actually alike. If the universe and watches were alike, then it would be supposed that the universe has a designers because as Hume says ‘like effects presuppose like causes.’ For instance, if I saw two chocolate Mars bars I would be able to assume that they had

Is The Human Race Still Evolving? The origin of evolution is humble. Humans have evolved over the years, and there has been a form of progression in their evolution. All creatures share one thing in common; reproduction. The process of reproduction allows for transfer of traits and characteristics which in the case of humans, derive theirs’ from their common ancestors. However these characteristics are similar but their genetic composition vary in one way or the other. For instance, the early

I listened to an interview with an evolutionary biologist named Jerry Coyne last week, and a question he was asked was: “If you were to present one piece of evidence for evolution to a non-believer, what would it be?” His answer: “The fossil record.” While I find the fossil record interesting, I find vestigial structures as the most compelling, and best to present to those who are evolution-deniers. Vestigial structures are features of species that have lost ancestral functions, and either have
