Sexual selection

Charles Darwin in his The Descent of Man and Karl Marx in his The Communist Manifesto suggest similar understandings of progress. For Darwin, progress manifests itself in natural selection, often known as “survival of the fittest,” where fittest refers to organisms that can survive and reproduce successfully and not to the most physically fit. Marx realizes that “the history of all hitherto existing society is the history of class struggle,” and thus understands progress as the removal of class…

within the population. Several studies have been done already to study the evolution of the periwinkle snails shell thickness. Seeley (1986) found that introducing crabs to a population of L. obtusata demonstrated a classic example of Darwinian selection. The snails with a smaller shell thickness were selected against and were not able to survive and reproduce. Therefore,…

book written by Bill Nye that describe evolution. After reading this book I had a different definition on evolution. Evolution is the process of growth in DNA by natural selection in an organism that can cause genetic defects such as mutations. As I described evolution to me now is the process of growth in DNA by natural selection in an organism that can cause genetic defects such as mutations. I developed this definition by listening to class discussions and reading the Bill Nye book. Taking…

The theory of biological evolution through natural selection is widely accepted and taught in most western education systems. However, there are many misconceptions regarding evolution, held both by proponents of evolution and by those opposing it. Generally, these misconceptions occur due to a misunderstanding or ignorance of how evolution functions, due to an over simplistic version of it being taught (Scott, 2004). The four misconception that will be discussed in this essay however, will be:…

Yahweh vs. The World on the Turtle’s Back “The World on the Turtle’s Back” and “Yahweh” share many similarities and differences. They both talk about two culture’s beliefs about how the Earth was created, and how the plants and animals came to be. “The World on the Turtle’s Back” comes from the Native American tribes while “Yahweh” is a Hebrew tale. Both are interesting tales and help us understand these two vastly different cultures. In “The World on a Turtle’s Back” there is a pregnant woman…

In our civilized world, we may not realize our world or the humanity has been civilized through hundred years of development. However, H.G Wells and Jean Rousseau are aware of the consequences due to the civilization. They believe civilization means a lot to the changes of humanity, creatures. They raise all sorts of questions on what is nature and what is artificial. Therefore, it is interesting to compare Jean Rousseau’s A Discourse on Inequality and H.G Wells’ The Island of Doctor Moreau in a…

Scientists, still to this day, are conducting research and observing facts on how and why primates have evolved throughout time. The study of primate evolution dates back all the way to Charles Darwin’s time where he proposed the processes of natural selection which is a very slow but gradual procedure. Since the time of Darwin’s theory some “factors that have influenced or are currently shaping community structures include historical circumstances, climate and habitats, productivity and food…

Writing Assignment #1 Lasiognathus dinema There are a couple misconceptions you might have about evolution and natural selection. The strongest and most important organisms do not survive over the generations. Although evolution occurs due to fitness in an individual or individuals of a species, an organism cannot survive over generations. Fitness is achieved through variations in populations of species through genetic differentiation (Scottville “n.d.”). Since the life cycle of all living…

Are we humans perfectly fitted to the world we live in today? Evolutionary psychology suggests this may not be the case. An important concept in evolutionary psychology is mismatch (link is external) (1). Evolutionary mismatch occurs when the environment that organisms are adapted to, via a slow process of biological evolution, changes so quickly and intensely that it hinders these organisms to fulfill their reproductive needs. Take an example from nature. Deforestation has changed the habitats…

Charles Darwin is a scientist that came up with the theory of natural selection to explain variation and evolution. Natural selection is the differential survival and reproduction of individuals due to differences in phenotype (Zimmer&Emlen, 2013). This means that in an environment where the condition is constantly changing, species that stay in that environment and use it as their habitat adapt to the changes of the environment to survive the changes and their off springs are also able to…
