Document Summary
Relevance of evolution to medicine field: emerging diseases rapid evolution and spread, origin of disease disease may evolve from another. Helps direct research: vectors of disease mode of transmission relates to effect of the disease. Malaria, water born diseases, airborne diseases: treatment of disease drug cocktails (need to remove variations of the disease that may be resistant). Evolved bc used to live in areas with iron poor diets. Relevance of evolution to conservation biology: low population numbers = low genetic variation of the gene pool, endangered populations are vulnerable to selective pressures, applied evolution improves crops and animal stock (artificial selection) . Agriculture and horticulture: weeds and feral animals dispersal of invasive species eg. cane toads. Stronger ones disperse further = if heritable then more will be stronger in future evolutions feral species becoming better adapted/bigger/faster (olympic village effect): crop mimicry (weeds) weed looks like rice.
