The nature or nurture debate is concerned the with the contributions of genetic inheritance, and environmental factors to human development. The nature theory says, although traits such as as eye and hair colour and genetics diseases are determined by genes, that there are also different qualities, for example, Intelligence, Personality, Homosexuality. Some others would say that, we learn or discovers all them above. We learn and improve our intelligences, we probably inherit certain personality traits from the things/people around us and some people may be curious of their preferences,
DESCRIBE AND EVALUATE EVOLUTIONARY EXPLANATIONS OF GENDER. Cultural and psychological differences between men and women are often referred to be a socialization consequence. Individuals are born in either one of the genders but they become feminine or masculine through a complex developmental process that takes many years to unfold. For example, Women usually look after the babies, while men usually provide food. The evolutionary approach argues that gender role division is a consequence of the adaptation to the challenges and circumstances faced by our ancestors.
Different cultures will select food their society is comfortable with or has a plentiful about of. For example in certain Asian cultures Canine is considered to be a delicacy, while in America Dogs are pets not food. Livestock throughout history has always carried a higher price than plants, the more livestock you owned the more wealth you possessed. Now different cultures place different values on livestock. For example Muslims, Hindu, and Jewish cultures find pork to be a taboo, in India they consider the Cow to be a scared animal.
Reticulum: in here, food and cellulose is digested by microbes ------ microbes are bacteria/ single celled eukaryotes ------ cows don't have enzymes to break down cellulose, so microbes do it for them ------ huge amounts of saliva create a good environment to help microbes digest the food ------ the food then goes back up to the esophagus to be chewed again and to make nutrients available for both cows and microbes --3. Omasum: water re absorption ------ Regurgitated food comes back as "cud" into reticulum and then to the Omasum --4. Abomasums: acidic environment where whatever is remaining is digested. excess microorganisms are harvested and digested. - NUTRIENTS (that they get): -- Sugars and proteins from grass are directly absorbed -- absorbing microbial digested grass molecules (cellulose --> glucose) --actual microorganisms themselves (they leak out sugars, fatty acids, etc.
Follow the directions below to collect the required data then use that data to answer the discussion questions that follow. Experiment 1: In this experiment you will be examining the effect of a mutation that changes the color of the organism and alters how it avoids predators. Before you start: Read through the experiment. Then in the space below hypothesize how this change in DNA will affect the evolution of this population over the next 10 generations.

Glossary Darwinian: Of or relating to Charles Darwin or his theory of evolution by natural selection. Microbe: Any microscopic organism, especially a disease-causing bacterium. Natural Selection: Is the process by which traits become more or less common in a population due to consistent effects upon the survival or reproduction of their bearers. It is a key mechanism of evolution.
Behaving Brain 1. Explain the major concepts of evolutionary theory, such as natural selection and variation. Charles Darwin created the theory of evolution and helped us to understand the roots of behavior and mental process. Natural selection states: variations increasing that odds of reproducing and surviving are most likely to be passed on to future generations, this has shaped our traits and behavior tendencies. Nature has selected advantageous variations from the mutations and new gene combo's produced at each human understanding.
Examine one evolutionary explanation of behavior Before we had the technology to look at genes specifically, a theory was used to explain how we’ve adapted the traits we have today. Darwin’s theory was that those who adapt best to an environment will have a greater chance of surviving, having offspring, and passing their genes to their offspring. As our environment is always changing, we need to adapt our characteristics to survive in that specific environment. It is the whole aspect of adaptation. It is said that those who are better suited for a certain environment will be more like to breed and pass on these genes also known as natural selection.
“Sociology has mounted a powerful attack on biological determinism.” For several decades, biological determinism has developed considerably in analyzing aspects of human behaviour. From explaining gender to mental disorders, supporters of the biological perspective argue that it is the biological factors such as an individual's genes and genetics completely determine how an individual behaves or changes over time. However, sociologists who study the human world, societies and individuals have criticised biological determinism as it fails to acknowledge environmental factors and influences when explaining human behaviour. This essay aims to discuss biological determinism in terms of gender and the arguments sociological determinists propose to critically evaluate the biological approach. Biological theorists when referring to gender behaviour and gender roles agree that gender is predetermined from biological processes, meaning that men and women think and act differently because of the differences in the brain development and activity (Sammons, 2009).
mating) challenges faced by our ancestors at greater frequencies. Both the natural and sexual selection theories have identified the primary forces that shape physiological and psychological mechanisms (Lieberman & Haselton, 2009). The principles developed by Darwin (1859) have proved to be invaluable tools for mapping the structure of the human brain and linking with our history. Darwinian evolution promotes the ‘survival of the fittest;’ the individuals who best adapt, and possess traits that give them a selective advantage within the environment are more likely to survive. Research into specific areas such as technology, social ties and how we apply the evolutionary approach to human behaviour has suggested that our modern human population is continuously
