In the late 19th century, Charles Darwin theory argued that the emotions were actually served a purpose for humans like in communication and also in aiding their survival. He also argued that emotions evolved via natural selection and later on had the universal cross-cultural counterparts. He proposed that this basic emotions and social emotions evolved to motivate behaviors that were had an adaptive value. Example, the fear emotion evolved because it enhances the capability of a person to survive. Darwin also believed that facial expressions of emotions are already existed when the time a person or animal was born. He mentioned that facial expression allows people to judge quickly on someone’s friendliness or hostility and on how the intentions
of individual to communicate with others. Not long ago, some evolutionary theories of emotion also consider emotions to be innate to stimuli. Evolutionary theorists believe that all human cultures share several primary emotions and all other emotions could result from blends and different intensities of these primary emotions. The different evolutionary theories were existed regarding on how and why people experiencing emotion. These theories are namely, the James-Lange theory, the Canon-Bard theory, Schacter and Singer’s two-factor theory, and Cognitive Theory.

scientists about how the heart rate and the blood flow to the face went together, but gives a different opinion and discovery. Reading about other scientists’ discoveries is intriguing, but Darwin’s specific discovery really does give perspective on the thoughts of scientists in the 1900s. An increase in heart rate is argued over whether or not it causes blush, but it happens when one is embarrassed, which makes scientists believe it is a cause of blushing.
Darwin in 1872 put forth the notion that emotional expressions are inborn and involuntary displays of one’s inner state (1). Darwin developed this ideology further and proposed what is now known as the Inhibition hypothesis (1). This two pronged theory describes the relation of emotion to facial muscle activation, more commonly known as facial expressions (1). The theory states that (a) specific facial muscles can not be intentionally engaged when the genuine emotion is lacking and (b) certain muscles can not be inhibited when a genuine emotion is experienced - it has been noted that this emotion must be particularly intense (Porter and ten Brinke, 2008; Porter, ten Brinke, & Wallace, 2011).
"On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life," usually shortened to "the Origin of Species," is the full title of Charles Darwin's book, first published in 1859, in which Darwin formalized what we know today as the Theory of Evolution. Although Darwin is the most famous exponent of this theory, he was by no means the first person to suspect the workings of evolution. In fact, Charles owed a considerable debt to his grandfather Erasmus, a leading scientist and intellectual, who published a paper in 1794, calledZoonomia, or, The Laws of Organic Life. This set down many of the ideas that his grandson elaborated on 70 years later.
Darwin and Evolution are inextricably linked in the minds of most people who have had the opportunity to study them in basic biology. However, Darwin's theories of selection and survival of the fittest have been applied to moral, economic, political, and other cultural aspects of society. Dennett briefly touched on some of the political and social ramifications of Darwin's theories in the final chapter of Darwin's Dangerous Idea. Other philosophers and thinkers have also adapted Darwin's evolutionary ideas, in order to apply them in a societal or cultural context. One great example of this adaptation of the biological concept of evolution, is the appearance of Social Darwinism during the 19th century.
Anyone with even a moderate background in science has heard of Charles Darwin and his theory of evolution. Since the publishing of his book On the Origin of Species by Means of Natural Selection in 1859, Darwin’s ideas have been debated by everyone from scientists to theologians to ordinary lay-people. Today, though there is still severe opposition, evolution is regarded as fact by most of the scientific community and Darwin’s book remains one of the most influential ever written.
Keith Henson a writer in evolutionary psychology once said that “Evolution acts slowly. Our psychological characteristics today are those that promoted reproductive success in the ancestral environment.” Evolution was first introduced by a naturalist by the name of Charles Darwin. Darwin had written an autobiography, at the age of 50, On the Origin of Species (1859) explaining how species evolve through time by natural selection; this theory became known as Darwinism. “Verlyn Klinkenborg, who writes editorials and vignettes on science and nature for the “New York Times”” (Muller 706) questions Darwin’s theory in one of his essays he wrote called Darwin at 200: The Ongoing Force of His Unconventional Idea. Both articles talk about the theory of Darwinism, but the authors’ use different writing techniques and were written in different time periods. Darwin himself writes to inform us on what the theory is, where as Klinkenborg goes on to explain why Darwinism is just a theory. Today, evolution is still a very controversial topic among many. It comes up in several topics that are discussed everyday such as in politics, religion and education.

One explanation that claims emotions are universal comes from Darwin (1872 in Smith & Kosslyn, 2009). Darwin adopted an evolutionary perspective of emotions by contending that emotions are universal which consist of biological components in which individuals are able to recognise emotional expressions of individual’s across different cultures. Definitions of emotions are many and varied. Emotions influence behaviour and can be positive and negative. They are also associated with physiological and cognitive changes and can influence behaviour (in Smith & Kossyln, 2009).
Charles Darwin came up with the theory of evolution and used the term natural selection to describe it. He proposed that all living species derived from a common ancestor. In On the Origin of Species (1859), Darwin explained: “if variations useful to any organic being do occur, assuredly individuals thus characterised will have the best chance of being preserved in the struggle for life; and from the strong principles of inheritance, will then tend to produce offspring similarly characterised” (p127).
The purpose of this academic piece is to critically discuss The Darwinist implication of the evolutionary psychological conception of human nature. Charles Darwin’s “natural selection” will be the main factor discussed as the theory of evolution was developed by him. Evolutionary psychology is the approach on human nature on the basis that human behavior is derived from biological factors and there are psychologists who claim that human behavior is not something one is born with but rather it is learned. According to Downes, S. M. (2010 fall edition) “Evolutionary psychology is one of the many biologically informed approaches to the study of human behavior”. This goes further to implicate that evolutionary psychology is virtually based on the claims of the human being a machine that can be programmed to do certain things and because it can be programmed it has systems in the body that allow such to happen for instance the nervous system which is the connection of the spinal cord and the brain and assists in voluntary and involuntary motor movements.
Emotions are (in part) for survival, and the more complex the emotion, the more complex the system to process it must be (both in theory and in context). If an emotion or mood is as simple as fight or flight, then this is something that is instilled in reptiles, mammals, and humans alike. These emotions are more easily figured out in the human brain, and seem to be easier to experiment with as well as find out about. There has been a large amount of research on the amygdala and fight or flight response, which as was stated above, is a basic emotion that reptiles, mammals, and humans all seem to have alike. The mor...
Charles Darwin has had the greatest influence on the world by proving the evolution of living things. Charles Darwin had first noticed the similarities of plants and animals when he took a five-year cruise on the H.M.S. Beagle, which was available to him through a friend from school. During the cruise Charles Darwin started becoming interested with the similarities between the plants and animals that were similar on different islands with similar climates, so he decided to study them more closely.
Emotion is the “feeling” aspect of consciousness that includes physical, behavioral, and subjective (cognitive) elements. Emotion also contains three elements which are physical arousal, a certain behavior that can reveal outer feelings and inner feelings. One key part in the brain, the amygdala which is located within the limbic system on each side of the brain, plays a key role in emotional processing which causes emotions such as fear and pleasure to be involved with the human facial expressions.The common-sense theory of emotion states that an emotion is experienced first, leading to a physical reaction and then to a behavioral reaction.The James-Lange theory states that a stimulus creates a physiological response that then leads to the labeling of the emotion. The Cannon-Bard theory states that the physiological reaction and the emotion both use the thalamus to send sensory information to both the cortex of the brain and the organs of the sympathetic nervous system. The facial feedback hypothesis states that facial expressions provide feedback to the brain about the emotion being expressed on the face, increasing all the emotions. In Schachter and Singer’s cognitive arousal theory, also known as the two-factor theory, states both the physiological arousal and the actual arousal must occur before the emotion itself is experienced, based on cues from the environment. Lastly, in the cognitive-mediational theory
Do animals feel joy, love, fear, anguish or despair? What ere emotions, and perhaps more importantly, how do scientists prove animals are capable of emotion? Sea lion mothers have often been seen wailing painfully and squealing eerily as they watch their babies being eaten by killer whales. Buffaloes have also been observed sliding playfully across ice, excitedly screaming “Gwaaa.” Emotions are defined broadly as psychological phenomena that help in behavioral management and control. This is a challenging question to researchers who are trying to determine the answer to this question. Through current research by close observation combined with neurobiological research, evidence that animals exhibit fear, joy happiness, shame, embarrassment, resentment, jealousy, rage, anger, love, pleasure, compassion, respect, relief, disgust, sadness, despair, and grief is likely. Charles Darwin said, “The lower animals, like man, manifestly feel pleasure and pain, happiness, and misery.” I agree with Darwin. I believe animals do exhibit emotions, and denying that animals have emotions because the subject cannot be studied directly is not a reasonable explanation.
