Charles Darwin Facts Charles Darwin was an English naturalist who changed the way humans viewed themselves and the world around them through his amazing ideas on evolution and natural selection. Read on for interesting facts, quotes and science information about Charles Darwin. Charles Darwin was born in England on the 12th of Februaryhe died on the 19th of April
It was based on observationsboth those around him and of people in many parts of the world. One important observation he made was that even in individuals who were born blindbody and facial expressions displayed are similar to those of anyone else. Most of the similarities he found were between species closely relatedbut he found some similarities between distantly related species as well.
He proposed the idea that emotional states are adaptive, and therefore only those able to express certain emotions passed on their characteristics.
The first of the three is the "principle of serviceable habits," which he defined as useful habits reinforced previously, and then inherited by offspring. He used as an example contracting of eyebrows furrowing the browwhich he noted is serviceable to prevent too much light from entering the eyes.
He also said that the raising of eyebrows serves to increase the field of vision. He cited examples of people attempting to remember something and raising their brows, as though they could "see" what they were trying to remember. The second of the principles is that of antithesis.
Naturalist Charles Darwin () is the father of evolution. His groundbreaking The Origin of Species argued that all species of life have descended over time from common ancestors, and proposed the scientific theory that this branching pattern of evolution resulted from a . The inception of Darwin's theory occurred during an intensively busy period which began when Charles Darwin returned from the survey voyage of the Beagle, with his reputation as a fossil collector and geologist already established. He was given an allowance from his father to become a gentleman naturalist rather than a clergyman, and his first tasks were to find suitable experts to describe. Darwin's theory of emotions holds that the basic emotions demonstrated by facial expressions are a universal language among all humans no matter what their cultural setting. Today, however, it is an accepted belief that although cultures share a universal facial language, they differ in how, and how much, they express emotion.
While some habits are serviceable, Darwin proposed that some actions or habits are carried out merely because they are opposite in nature to a serviceable habit, but are not serviceable themselves. Shrugging of the shoulders is an example Darwin used of antithesis, because it has no service. Shoulder shrugging is a passive expression, and very opposite of a confident or aggressive expression.
This principle proposes that some habits are performed because of a build-up to the nervous systemwhich causes a discharge of the excitement.
Examples include foot and finger tapping, as well as vocal expressions and expressions of anger. Darwin noted that many animals rarely make noises, even when in painbut under extreme circumstances they vocalize in response to pain and fear.
Emotion in animals Paul Ekman is most noted in this field for conducting research involving facial expressions of emotions. He conducted research by showing photographs exhibiting expressions of basic emotion to people and asking them to identify what emotion was being expressed.
InEkman and Wallace Friesen presented to people in a preliterate culture a story involving a certain emotion, along with photographs of specific facial expressions. The photographs had been previously used in studies using subjects from Western cultures.
These results indicated that certain expressions are universally associated with particular emotions, even in instances in which the people had little or no exposure to Western culture.
The only emotions the preliterate people found hard to distinguish between were fear and surprise. The expressions of emotion that Ekman noted as most universal based on research are: Thus, the widened eyes in the facial expression of fear have been shown to increase the visual field and the speed of moving the eyes which helps finding and following threats.
The wrinkled nose and mouth of the facial expression of disgust limit the intake of foul-smelling and possibly dangerous air and particles.
Later, such reactions, which could be observed by other members of the group, increasingly become more distinctive and exaggerated in order to fulfill a primarily socially communicative function.
This communicative function can dramatically or subtly influence the behavior of other members in the group. Thus, rhesus monkeys or human infants can learn to fear potential dangers based on only the facial expressions of fear of other group members or parents.
Seeing fear expressions increases the tendency for flight responses while seeing anger expressions increases the tendency for fight responses. Cross-cultural studies and studies on the congenitally blind have found that these groups display the same expressions of shame and pride in situations related to social status.The proper development and functioning of emotions allow people to live well and to be happy.
Love, respect, and compassion, for example, are the essential emotional ingredients of . Darwin's Theory of Evolution - Natural Selection While Darwin's Theory of Evolution is a relatively young archetype, the evolutionary worldview itself is as old as antiquity.
Ancient Greek philosophers such as Anaximander postulated the development of life from non-life and the evolutionary descent of . Darwin's Camera tells the extraordinary story of how Charles Darwin changed the way pictures are seen and made.
In his illustrated masterpiece, Expression of the Emotions in Man and Animals (), Darwin introduced the idea of using photographs to illustrate a scientific theory--his was the first photographically illustrated science book ever published. The study of the evolution of emotions dates back to the 19th urbanagricultureinitiative.comion and natural selection has been applied to the study of human communication, mainly by Charles Darwin in his work, The Expression of the Emotions in Man and Animals.
Darwin researched the expression of emotions in an effort to support his theory of evolution.
He proposed that much like other traits found in. In the section on man, Darwin judges that expressions of emotions are best studied in the insane because their emotions are more fixed and exaggerated; he quotes Sir James Crichton-Browne's description of patients with ‘melancolia’ (depression) and ‘hypochondria’ as showing the contraction of what he calls the grief muscles, causing a.
