Furthermore, there is a vast need for additional research. There is a necessity to gain knowledge on risk factors and on ways to prevent suicide in order to aid nursing home residents (Bugeja et al., 2015, p. 811). The knowledge of preventing suicide in a nursing home can be helpful for residents as well as for social services. Suicide occurs in nursing homes partially fur to the lack of knowledge on depression. Current research depicts that physicians fail to recognize depression and tend to provide inaccurate treatment (Allgaier, Fejtkova, Hegerl, Kramer, & Mergl, 2009, p. 355).

In Biology Natural Selection is the key process behind the theory of evolution but not the only one. Charles Darwin introduces us first with this important theory of life in earth He conclude that species are specially modified to their environment that’s why they are different. There are four conditions that explain why this happens: 1. Individuals within a population differ.

In addition, when Darwin was around twenty two years old he was invited to a five-year voyage. What no one knew, was that this voyage would later become one of the key experiences for the development of his ideas and thoughts about the natural life. During his voyage, Darwin developed the scientific theory of biological evolution, which explains how modern organisms evolved over long periods of time through descents with modifications from common ancestor (3). To understand this concept better, descent with modification is the fact that when parents have children, those children often look and behave slightly different than their parents. Additionally, the idea of a common ancestor is the idea that all living things are related because they descend from a common ancestor (6).

Since Darwin first suggest his concepts about biological evolution and natural selection various lines of research from many different branches of science have produced evidence supporting Darwin’s belief that biological evolution arises partly due to natural selection. The environment selects certain species because of advantageous characteristic and ability to adapt to the environment in compared to other species. Fossil record illustrates this through old rocks animal remains showing simple to complex evolving. One area is comparative anatomy, which has shown similarities in structures of different living organisms, such as the skeletons of humans, bats cats, and bats. Even though these species live in different climax and environment

Many scientists have proposed theories relating to evolution, and Charles Darwin’s theory of evolution is the one that is accepted today. In 1859, he proposed his own theory, which consisted of the concept of natural selection and ‘survival of the fittest’. He spent most of his life researching on an island and had concluded that organisms alter over time “as a result of changes in heritable physical or behavioral traits” (Ker Than, 2015). Darwin also concluded that favorable changes in an organism allowed the organism to remain alive. The phrase ‘survival of the fittest’ sums this conclusion up; the phrase

Introduction Evolution is a process through changes and transformations that happen in living beings over time, giving advancement for new species for our ecosystem. In the 19th century, Darwin helped this evolutionary theory gain strength; he believed that our evolution was based on Natural Selection, and what he explained evolution using genetics facts. He also believed that evolution is descent with modification, or is a change in the genetic composition of a population from generation to generation (Reece et al. 2010). The main idea of biological evolution is that all living being share the same ancestor.

Charles Darwin was an English naturalist, geologist, and biologist best known for his contributions to the evolutionary theory. He was definitely not the only person who hypothesized an evolutionary theory. Lamarck, who was also a naturalist, supported that biological evolution came about and progressed aligning with the laws of nature. Lamarck’s evolutionary idea was the theory that the environment affects the form and organization of animals implying that when the environment changes it causes the animals to adapt according to the modification. The major changes in the environment of animals’ causes great changes in their needs necessarily leads to other changes in their activities.

In the past species differed somewhat or greatly compared to their contemporary decedents and such species may display differences in other parts of the world climate compared to the same species in other climates on the earth. In addition, Darwin contends that all organisms share one common ancestor with other organisms, meaning that over time, populations may separate and split into other species, which all share a common ancestral population. Finally, Darwin asserts that evolution is a slow and gradual process. This means that there will be slight changes to a species over a short period of time, but that in the long run (say, in a million years) that species will be drastically different if not unrecognizable by that point in history; due to all the slight and small changes over the course of a slow and gradual process that took millions of years to get

Although the theory of evolution is ancient, Darwin’s version is a relatively new archetype. Greek philosophers, such as Anaximander, believed in the origination of life from non-life, and the evolutionary descent of man from animal. However, Charles Darwin takes evolution a step further, supplementing this ageless theory with the ideas of natural selection. This doctrine states that nature acts to sustain small, advantageous genetic mutations, and that the fittest individuals survive (Darwin’s Theory of Evolution). Therefore, “[n]atural selection is the preservation of a functional advantage that enables a species to compete better in the wild” (Darwin’s Theory of Evolution).

Before the publication of Natural Selection in 1859, Western scientists were beginning to uncover significant pieces of information on the Earth and their organism inhabitants. Darwin bases his theory on three key realizations that many scientists had deemed to be profusely influential by the late 1700s.

As Charles Darwin voyaged through the Galapagos Island, he discovered something quite surprising: many of the different animals that he had observed seemed to have similar structures. After a long period of consideration, he soon came into conclusion; these different species might have originated from common ancestors. This idea is what establishes the root of modern Biology; it depicts the variation of species and how these animals came to be. The book, On the Origin of Species, is a scientific literature written by Charles Darwin. It is often considered as the “foundation of biology” and focuses on the idea of natural selection.

Introduction Evolution is the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of earth. The theory of evolution by natural selection, first made or talked about in Darwin's book "On the Origin of Species" in 1859, which is the process by which organisms change over time as a result of changes in heritable physical or behavioral traits. Two very important scientists, Charles Darwin and Alfred Russel built up the evolutionary thought laid by Lamarck; using their ecological knowledge and worldly experience, they slowly start to develop the theory of evolution. The evidence we have in biology today to prove the theory of evolution are: 1. Species share similarities

The theory of evolution by natural selection and the evidence presented by Darwin. The evolution of biological organisms describes the changes within different populations which creates variability in their phenotypes and genotypes. The fundamental basis of evolution, is that every living individual is related by a common ancestor (Strickberger,2000.). Charles Darwin, in 1859, published one of the most credible and compelling theories of evolution, in his book ‘the origin of species’ (Darwin and Beer, 2008), which best explains the theory of natural selection.
