Document Summary
The study of the evolutionary history of life: sometimes it"s used more narrowly to refer to naming and describing species but it won"t be used for that in this class. Understand adaptations of organisms to their environments. Conservation: to conserve organisms, we need to know what is there. Diagnostics: to identify a pathogen, we need criteria, ex. Ebola outbreaks have been reported in central and. Ongoing ebola outbreak in west africa: as of april 2016, 28616 confirmed cases, 11310 deaths: previously, largest outbreak was in 1976 and there were 318 cases. Genomic surveillance elucidates ebola virus origin and transmission during the 2014 outbreak. Where did it come from, who does it affect, how has it changes, what are the patterns of transmission. Next generation sequencing of the virus isolates from 78 patients in sierra leone; additional 3 isolates from guinea. Phylogeny: evolutionary relationships between individuals, species, genera, etc.
