“Vestigial Organ” is a term used to describe organs or functions that due to the course of evolution no longer have a use. The idea of useless organs had been around long before Charles Darwin, but his idea for why they were there was the one that stuck. In his book “The Descent of Man” Darwin named a few organs that were considered absolutely useless or had very little service such as wisdom teeth, the appendix, the spleen, and the hind leg bones in whales. While functions of some of these parts
Is “theory” a contradictory scientific term? Many people define “theory” as a set of unjustifiable propositions, whereas others believe a “theory” is a “coherent set of principles used to explain a class of phenomena” (Kingsolver 208). The contrasting interpretation of “theory” results from the fluctuating amount of information circulating on this term. Although the word “theory” is a prime example of how people interpret ideas distinctively, people can develop new insights on their previous ideas
Humans, or Homo Sapiens, are extremely intelligent beings with complex cognitive and manipulative abilities who have taken over the world. How did humans come to be such a skillful and dominant species? Scientists for years have sought to fully understand the physical and cognitive evolution of the hominin clade. If human evolution did start off with apelike habits, why are there human traits such as terrestrial bipedality, toolmaking, and larger brains? When did these traits emerge? What gave rise
Evolution of the Mid Range Theory of Comfort for Outcomes Research Katharine Kolcaba, PhD, RN, C The developmental stages of the mid range theory of comfort are discussed in this article, which includes its philosophic orientation and its inductive, deductive, and retroductive reasoning. Other steps that are described are the concept analysis of comfort, the operationalization of the outcome of patient comfort, the application of the theory in previous nursing studies, and the evaluation of the
along the ventral midline of the human body. Some of these abnormalities include a cleft lip, heart defects, wide-spaced eyes (hypertelerism), laryngeal cleft, agenesis of the corpus callosum, and hypospadias. An important irregularity in patients is the effect disrupted proteins have on the corpus colloseum. The corpus colloseum is a neuronal component that separates the two halves of the brain. This protein is imperative because it controls MID-1 or the midline. The MID-1 protein also forms homodimers

Since Charles Darwin suggested the theory of evolution by natural selection in this best-known work, On the Origin of Species, controversy has followed. As a (computer) scientist, this student has no personal problem with the theory of evolution. However, since the debate of whether or not evolution actually exists is still alive and well today, a brief exploration of the arguments against is not only interesting, but also increasingly necessary. Why is there such disparity over this topic over one
Scientific Abuse Darwin, the name widely recognized as the grandfather of evolution, describes evolution as “organ, instinct, or any whole being...arriving at its present state by many graduated steps” (Darwin 158). The struggle for survival forces organisms to evolve gradually and adapt to their environment, therefore increasing their chances of survival. Darwin furthers his theories into the origins of species in which he explains how “several breeds to which each has attended, are descended from
Why Evolution Is True Oakley T. Lowe St. Leo’s University Abstract Throughout history, there has been a major debate on the theory of evolution. Is it true? The term evolution has been defined many ways, and for the purpose of this paper, I will use the fourth definition from the Merriam-Webster dictionary. “Evolution is the descent with modification from preexisting species: cumulative inherited change in a population of organisms through time leading to the appearance of new forms: the process
DEFINING DIVERSITY: THE EVOLUTION OF DIVERSITY by Camille Kapoor 1. INTRODUCTION: WHAT IS DIVERSITY? The concept of diversity encompasses acceptance and respect.
