Document Summary

Is a study of the diversity of life and evolutionary relationships. It involves identifying, describing, classifying and naming of organism. It allows us to us which organisms are which are how are they related. E. g. lactrodectus (black widows) which produce neuron toxin and streatoda are called false widows. Instead it takes away the toxin if you are bitten by a black widow. Conservation is to preserve species and damaged landscape. The best model for a particular research problem may depend on evolutionary relatedness. So knowing an organism"s identity and evolution lineage can be crucial. And there are 2 kinds of systematics: traditional evolutionary systematics. = overall similarity and differences: phylogenetic systematics is evolutionary relationships. Phylogenetic trees or cladograms is a picture that shows us our phylogenetic relationship. Traditional evolutionary started from carl linnaeus and proposed 2 things. 2015: taxonomic hierarchy arranges organism into hierarchy of increasingly inclusive categories. Members of a particular taxonomic level share certain key feature.
