In The Fearless Vampire Conservator: Philip Kitcher, Genetic Determinism, and the Informational Gene, Paul Griffiths defines genetic determinism as “the idea that significant human characteristics are strongly linked to the presence of certain genes.”(pg number). Griffiths argues that the common characterization of genes as informational, in both science and general society, is problematic because it causes our concept of genetics to be inextricably linked to genetic determinism. He explains that “the predominant vernacular conception of information is intentional information,” which is context-independent, leading to an association between genetics and determined health and behavioral phenotypes. To provide evidence for this thesis, …show more content…
A template is “material used as a pattern for processes” (SORUCE DICTIONARY). Double-stranded DNA, during transcription, is used as a pattern by RNA polymerase to create a single-stranded, complementary strand of mRNA. In translation, a protein is created using the linear structure of mRNA, which along with other structures like tRNA and ribosomes, attracts specific amino acids, lines them up in a precise order and attaches them together. DNA can also be replicated during certain times in the cell cycle. Thus, genes can be described as templates for specific RNA sequences, which may or may not be templates for protein products. A genetic template can be used by other cell structures in ways that are dependent on the micro- and/or macro-environments. This minimizes a gene’s role in larger processes by defining it in less deterministic molecular terms: as a helical stretch of nucleotides (with a phosphodiester backbone) that contains triplet codons which, when transcribed into mRNA, attract specific amino acids. In this way, a gene has a finite set of mRNAs (and subsequent proteins) that it can code for, but it is not ascribed a finite set of larger outcomes, like behaviors, that it determines. Describing DNA as a template for non-coding mRNAs and proteins allows genes to be informational without giving them an intentional and deterministic role in development and behavior. The template definition of a gene also
“Trying to separate out nature and nurture as explanations for behavior, as in classic genetic studies of twins and families, is now said to be both impossible and unproductive” (Levitt, 1). Social scientists have declared the nature-nurture debate to be unnecessary. Similarly, scientists feel that such debate is not only unhelpful, but also outdated. From geneticists’ perspective, nurture and nature interact to influence
The reading begins with an introduction to what the study is about. The study is about trying dismiss the notion that solely your surroundings and experiences (nurture) or your genetics (nature) is solely the cause for you becoming the person you are today. It begins by explaining how the psychological world was very behavioristic during the later parts of the 20th century. Meaning, people assumed that their surroundings had a lot more influence on their lives, than the genes that they had. The reading also states that people are less likely to accept that they made a choice based on their genetics because it feels like a lack of
Both normative and nonnormative influences and nature and nurture influences both shed light on human development over childhood and adolescence. The nature and nurture debate refers to whether particular aspects of development are a result of inherited characteristics (nature) or obtained characteristics (nurture). The answer to what characteristics were obtained by which source is a difficult task as there is still much to learn about the way genetic markers work and how their patterning influence organisms. Instead nature and nurture should be looked at as a intricate ecology (Claiborne, Drewery, Paki, & Peters, 2014). This is where characteristics are not considered to have only a single source but can linked to a contribution of our genetic
Do our genes affect our decisions? Can the environment alter our genetic makeup? In Sharon Moalem’s work “Changing Our Genes,” he writes about how the environment around us and our ancestors has contributed to the making of our genes. Genes are the instructions to make proteins which is ultimately the making of us. In Kevin Beaver’s “Genetic Influences on Adolescents,” he emphasizes the groundbreaking research in the similarities of children’s eating habits compared with their siblings and how genetics is a contributing factor. Our genes do not define us, but they do play a role in what our choices in life will be. One of the choices we make is regarding our lifestyle, specifically, how active we are and what we choose to consume. Additionally, Liam, a 12-year-old boy in the documentary film Overfed and Undernourished who has obesity realized that in order to avoid healthy problems at such a tender age and to live a longer more active life he needs to combat his excess weight. Also in “The Epidemic of
David Epstein argues that genetics are the main factor in the story of people's
The world we live in, we like to depend on scientific findings to reason our claims. This reaction paper will analyze the findings by Mathew Jones and will critique specific sections on "Genetic Research Summarized" and "The Resulting Concern". Now if we solely depend on genetics to defend or accuse individuals of being a criminal it will not be an efficient strategy in the criminal justice system. Furthermore, although American Criminal Justice upholds the notion of free will, it has been discriminatory towards a marginalized population of the United States itself. So being dependent on such findings there will be a higher probability of wrong people being trialed because then the idea of free will and genetically findings will be in conflict.
The field of genopolitics has become a newly popular topic linking the world of genetics with the world of politics. For centuries, biologists, physiologists, as well as many other scientists have looked to link certain traits of the human body with outside behaviors, beliefs, and even intelligence. This idea of genopolitics goes hand in hand as it makes an effort to discount environment as the reason for a person’s political beliefs, and instead, it looks to identify neuroscience or the development of genetics as the primary reason a person believes what they believe politically.

The idea that our genetic code controls most aspects of our lives is arguable. Nowadays, scientists (cell biologists, neuroscientists, etc.) are uncovering concrete evidence that are genetic code is only one of the many complex system of the human body that sways our lives. According to one new study, (“Do
It has been argued that if genes influence behaviour and character, and we cannot choose our genes, then our behaviour is outside our control and we are not responsible. However, we take the view that genes are not deterministic, and that there is scope for an
The world of Genetics is one that is both fascinating and interesting. When tackling how genetics plays a role in behavior, one must look within the scope of what genetics is before dealing with how it plays a significant role in one’s behavior. Simply put, genetics is the study of genes. It is a biological component within the entire study of biology itself. Scientists who study genetics and perform research do so with the intent to learn more about how genetics affects the overall attitudes, behaviors and dispositions of individuals. It could be said that genetics is somewhat of a psychological-biological science as researchers look at the underlying patterns within the genes that cause
This principle, “one-gene, one-protein” is the idea that every gene within a DNA sequence is responsible for producing one protein. The idea was presented by George Beadle and Edward Tatum in their theory called “one-gene one-enzyme.” These two theories are essentially synonymous in the main ideas presented, with only slight differences. The theory, “one-gene, one-protein” explains how genetic material is expressed within organisms; however, it does not explain the tie between gene-protein production and then protein-phenotype production. Genes dictate the structures of all the proteins produced by an organism (Freeman). When thinking of the “one-gene one-protein” theory, however, most people automatically think “one-gene, one-phenotype.” This is incorrect, even though it is often times what it observed in the natural world.
Is behavior learned? It is inborn? What of aggression, intelligence, and madness? There is a crucial relationship between the behavior of humans toward their own kind and the view of life they hold. Interest in behavioral genetics depends on wanting to know why people differ. According to Jack R. Vale, in Genes, Environment, and Behavior, recognition of the importance of hereditary influence on behavior represents one of the most dramatic changes in the social and behavioral sciences during the past two decades. A shift began toward the more balanced contemporary view that recognizes genetic as well as environmental influences on behavior. Behavioral genetics lies in its theory and methods, which consider both genetic and
One of the fundamental discoveries of the 20th century was that DNA was the genetic code’s physical structure (Watson & Crick, 1953) and, since then, many studies have disclosed the complicated pattern of regulation and expression of genes, which involve RNA synthesis and its subsequent translation into proteins.
