1) Superabundance
Plants and animals produce offspring necessarily merely to

taken and disadvantageous characteristics are selected against
oSelection pressures

to survive

Document Summary

Darwin: human emotions serve primitive functions, showing of teeth when angry: done when man once was lower and in animal like condition. Elements of evolutionary approach to emotions: 3 parts that drive evolution, superabundance. Plants and animals produce offspring necessarily merely to produce themselves: variation. Each offspring is somewhat different than others, and differences passed by heredity: natural selection, characteristics that allow individual to adapt to environment are taken and disadvantageous characteristics are selected against, selection pressures. Physicals features that evolve based on social environment, that were needed to survive: sexual selection pressures. Traits that are positive (strength, beauty, intelligence) will more likely be passed onto succeeding generations. Intersexual competition: when one sex picks particular traits to mate with, women picking men of higher status, adaption www. notesolution. com.  adaption"s are genetically based traits that allows organism to respond well to section pressures and to survive and reproduce.
