Biston betularia, commonly known as the black and white moth or pepper moths, is a good example to show how natural selection influences the features of a species. Natural selection involves four key parts consisting of variation, influence of the environment, survival of the fittest and population changes. All populations have genetic variation which can be passed on. Some variations are more favourable than others, making those individuals better suited to their environment. Individuals with more favourable variations are more...
Evolution is the development of life on earth. This process began billions of years ago and is continuing to this day. Evolution tells us how the enormous diversity of life could develop. It refers to any change in the distribution of alleles within a population over time. In the early 19th century Jean-Baptiste Lamarck (1744–1829) was the first to fully form an evolution theory of the transmutation of species. In 1858 Charles Darwin and Alfred Russel Wallace, both naturalists published...
Specific interpretations in Darwin’s theories of evolution pose challenges to modes of proceeding within feminist critique. Since the conception of his theories of natural and sexual selection in the mid to late 19th century, it has been ‘easier to imagine Darwinism and feminism as adversaries rather than allies’. Women authors in the 19th and early 20th centuries did lots of critical groundwork in revising Darwin’s theories to uncover and challenge the stereotypes that subordinated women, which gained validation under the...
Much debated topic among psychologist are always, whether our personality and behaviour are governed by nature or nurture. Evidence from various psychologists’ study have very much agreed that both also can influence and shape who we are. But to what extent, or which is more important is still an ongoing debate. The following contents of this essay will describe about two psychology branches: Evolutionary Psychology and Behavioural Genetics, to dwell on their root’s origin, ideology approach and methodology used of...
Introduction Throughout history a number of alternate theories of evolution have been proposed by equally intelligent scientists, most notably the theories of Jean Baptiste Lamarck, Charles Darwin and Alfred Russel Wallace. As with various theories, many tend to raise the question as to which theory has had the greatest contribution to modern evolutionary theories. Evolution is the one of the fundamental keystones of modern biological theory, through which organisms gradually changes over an extended period of time in response to...

John Wyndham’s book title is slightly ambiguous due to the fact that he invented the word for his book, but it originates from the word “chrysalis”, a stage in the butterfly life cycle. The Chrysalids is a book about the aftermath of a nuclear war, and the struggle of people who are different. The novel follows three main groups, the people of Waknuk, the Fringe people, and the Sealanders. Every group represents a stage in the cycle: caterpillar, chrysalis, and...

Plato to Darwin to DNA highlights the different understandings of our natural world throughout history. Not only is the reader able to get a detailed view of each periods method of research and development of theories, but also is able to compare them with one another. The “scientific process” as we know today was incredibly different in the past, and explanations of our natural phenomenon were determined by direct observations and deep philosophical thought. The reader is also able to...
Evolution happens when processes such as natural selection occurs resulting in certain characteristics becoming more common. The fossil record is a history of life documented by fossils and the remains and imprints of organisms from much earlier times. Over time changes have occurred in features of organisms living on the planet. One example of evidence from fossils is the transitional form of Pakicetids (an early ancestor to our modern whale) it had nostrils located at the front of its skull...
Radio is one of the longest standing mediums to come to our generation. As technology changes so does the world around us. In radio, this change has been seen with the push for analog/terrestrial radio to move toward HD radio. Traditional radio has been limited to amplitude modulations was the main frequencies used in the early years. This is followed by the main use of frequency modulations coming into the market. To understand the power of HD radio along with...
Evolution is a theory or scientific notion which conveys the idea that all life in our world has developed over time and continues to change by a process known as natural selection. Every living creature has participated in the evolution of their species, that’s right, even us humans. An animal whose evolution goes back as far as 30 million years is our very large furry friend, the bear. Bears are classified in the Ursidae family which includes eight altering species...
