Ex many robins common name but all differen6 scientific names Mountain Lion, cougar, Puma, Florida Panther all same scientific names
Scientific names serve 4 main purposes: Help scientists avoid errors in communication

3 gives descriptive information about the species
4 Allow information to be organized and found easily and efficiently
Scientist look at ________ ______, similarities in _____ and ____ __________, and _______ and the _______ to fin the organisms phylogony chemical makeup, genes, body structures, fossils, and embryos
