EVOLUTIONARY THEORY Evolution is the process in which significant changes in the inheritable traits (genetic makeup) of a species occur over time. The validity and value of evolutionary biology are based on continual analysis and interpretation of accumulating science data. THEORIES OF ORGANIC EVOLUTION • Historically three theories • The views of most modern biologists combine the second and third • No evidence of the first theory‚ that of Lamarck LAMARCK: Inherited Acquired Characteristics

The Evolutionary Theory of Attachment Bowlby’s evolutionary theory consists of a number of essential factors. The evolutionary theory of attachment as proposed by John Bowlby (1907-1990) suggests that attachment‚ in terms of adaptation‚ is essential for survival. In order to progress healthily‚ children are born with an innate tendency to form attachments. This means that infants are pre-programmed to become attached to their caregiver. This is supported by the research of Lorenz (1952) in

Theory of Evolutionary Psychology PSY 331 Instructor Malish Jan. 11‚ 2012 The Evolutionary theory of learning is a sub- category of the school of Evolutionary psychology. The study of evolutionary psychology focuses on a combination of sciences‚ evolutionary biology and cognitive psychology‚ anthropology‚ and neuroscience. The basic theory seeks to explain‚ through universal mechanisms‚ why humans act and learn the way they do. EP (evolutionary psychology) theorists attempt to reconstruct early

Evolutionary Theory of Attachment The evolutionary explanation of attachments was first developed by Bowlby. He said that an attachment is biological and crucial for survival as it ensures the infant is cared for due to the reciprocal nature of attachment. Bowlby also said that both infants and carers are innately programmed with the ability to make attachments and that Bowlby believes in monotropy‚ the belief that a child can only create an attachment with one primary caregiver only and this

Examination of the Role of Evolution Theory in Predicting Criminal Behavior Walden University 9/23/2012 Abstract In this paper I will briefly describe the evolutionary theory in general‚ and specifically as it relates to the study of criminology. I will examine the ways in which natural selection has shaped the processes which motivate human behavior‚ especially in terms of how competing for limited resources and ensuring that one’s genetic code is passed on are linked to aggressive behavior

07/09/12 Bowlby’s Evolutionary Theory “Babies’ smiles are powerful things‚ leaving mothers spellbound and enslaved. Who can doubt that the baby who most readily rewards his mother with a smile is the one who is best loved and best cared for?” – Bowlby‚ 1957. John Bowlby was a psychoanalyst (like Freud) and believed that mental health and behavioral problems could be attributed to early childhood. Bowlby’s evolutionary theory of attachment suggests that children come into the world biologically

Theories of Sleep The ’Restoration Theory’ is a psychological approach to sleep which claims that we need to sleep in order for our brain to restore energy resources depleted from biological processes throughout the day and remove any useless waste from the muscles. Oswald’s research in 1966 proposed that the brain and the body are restored through different stages of sleep‚ the former being restored during rapid eye movement sleep and the latter during slow-wave sleep‚ part of non-rapid eye movement

Evolutionary psychologists believe that aggression is linked through genes and has been maintained biologically as people have adapted to the changing physical and social demands of the environment. In the past‚ males that found other mates desirable found it necessary to compete with other males. The most successful male was the most aggressive. This aggressive behaviour made sure that the fittest males survived and were more successful in securing mates and passing on their genetic fitness to their

Vanessa Campos 10/15/2015 Anth 300: Essay 1 Professor: Katrina Worley Genetics and Evolutionary Theory There are some people out there that don’t believe in science such as evolution‚ natural selection‚ genetics‚ and so on. You name it. Anyway‚ the theory of evolution for the development of species is a theory. Not all scientists can get the truth because it a little hard work to get the evidence but their theory says it can happen to this or that. There are three way to explain in science‚ what

The Role of Primate Sociality in Evolutionary Theory Introduction Some animals‚ and more specifically primates‚ have been noted for having brains of an uncommonly large size. One explanation for this phenomenon is the ‘social brain’ or ‘social intelligence’ hypothesis‚ which states that brain sizes have increased in order to handle the demands of sociality (Lindenfors 2005; Pérez-Barbería et al. 2007). The increase in brain size can be attributed to the computational power needed to track
