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 variables to shape our level of health and well-being across the lifespan. We are just beginning to understand how epigenetic processes integrate nature and nurture epigenetics is positioned to profoundly change the way we think of human development in the 21st century. Evolutionary theories propose that the genetic and physiological processes that underlie human behaviour changed gradually over time through genetic mutation and natural selection. Our body cells" nuclei contain 23 pairs of chromosomes that are made up of about, an astounding, 2. 0 metres of finely coiled deoxyribonucleic acid (dna) molecules. Each chromosome is divided into segments, called genes, each of which influences a particular feature or developmental pattern. A gene controlling a specific characteristic always appears in the same place (the locus) on the same chromosome in every individual of the same species.
