Document Summary
Evolutionary perspective: darwin: theory of evolution. Natural selection supports behaviors that increase ability to reproduce. Using evolutionary psychology to understand development: evolutionary perspective. Natural selection operates primarily on characteristics tied to reproductive fitness. As older adults weaken biologically, need for culture-based resources increases. Evolutionary pressures created changes in biological structures. Tools help to manipulate environment and construct new conditions. Led to consciousness, thought and language: foundations of development. Directs body processes through the direction of cells reproduction and protein assembly. Helix shape: genetic foundations of development. Mapping of complete set of developmental instructions for creating proteins to create organism. Genes collaborate w/ each other and w/ nongenetic factors. Each chromosome in cell"s nucleus duplicates itself. Cells divide into gametes (sperm/eggs), which have half the genetic material of parent cell. Provides more characteristics for natural selection to operate on. Dna changes due to enviro damage or issues. Genotype (genetic) and phenotype (physical) differences: genotype- genetic material, phenotype- observable/measurable characteristics.
