Document Summary
Chapter 2: independent questions: biological and evolutionary theories. Summarize the two introductory paragraphs of this section. Both genetic and epigenetic factors interact with environmental variable to shape our level of health and well-being across lifespan. Genetic and physiological processes that underlie human behavior changed gradually over time through genetic mutations and natural selection. Evolution used to explain cognitive, social, cultural behaviours: genetics. Moshe szyf and michael meaney found that epigenetic factors play pivotal role in lifespan development. Maternal care can physically alter molecular epigenetic structures in offspring (ex. Mother rat"s increased postnatal feeding and grooming of her pups resulted in calmer rat pups by altering molecular epigenetic structures) Some epigenetic modifications can be passed on from one generation to the next; even epigenetic changes caused by changes in maternal diet have been passed on in mice populations. Acquired epigenetic traits linked to chromosome structure alterations may be inherited in humans. Describe this theoretical view and identify the example provided.
