Darwinisms Of Evolution

The idea that both living organisms and the earth change consistently can be traced to the ancient Greek (Hergenhahn & Henley, 2014). Despite all these well-known facts it can be claimed that the evolution of living organisms has been considered as a scientific way of thinking concurrently with Charles Darwin (1809-1882) as a result of the fact that Darwin stated the mechanisms of these changes in a systematic and detailed way besides he came up with convenient evidences in his most famous and impressive book On the Origin of Species (1859) (Pickren & Rutherford, 2010). Darwin’s theory of evolution by natural selection consists of three fundamental principles. First, all living organisms produce offspring as much as they are able
In his second book, The Descent of Man (1871), Darwin claimed that both humans and great apes came from a common ancestor and this ancestor was a primate (Hergenhann & Henley, 2014). In the next book, The Expression of Emotions in Man and Animals (1872), Darwin suggested that human emotions are residues of animal emotions that were developed for survival. In addition to this, Darwin proposed that human emotions are cross cultural or universal so we can determine one’s experience anywhere in the world by observing his or her facial expression. Finally, in The Expression of Emotions in Man and Animals Darwin compared humans with other animals and he figured out that differences between human and other animals result in only in degree. Therefore, scientists became certain that a lot of phenomena about humans can be learned by investigating nonhuman animals. These claims were strongly and directly related to psychology and they became the cornerstone of a new scientific way of studies in psychology which was later called comparative psychology. (Hergenhann & Henley,
Specifically, comparative psychology is a scientific way of study that investigate the evolution and development of animal behavior in order to obtain general principles that are able to explain the origins of all behavior in all animals. Therefore, comparative psychology indicated a new scientific way of study that was based on comparison of humans to other animals. In this way, comparisons can uncover both the similarities between humans and other life forms and the human characteristics differ from other species that make us unique in the world (Greenberg & Haraway,
