Transcript of Human Biology Lecture On Taxonomy Homologies Evolutionary Systemics Cladistics And Brains
Professor Jeff McKendricks
Human Biology Lecture on Taxonomy, Homologies, Evolutionary
Systemics, Cladistics, and Brains
Species
• The term species has its origins in the ancient Latin language. In this language, the word species means kind.
Binomial nomenclature
• Linnaeus suggested that every organism should be classified with a unique binomial name.
Genus.speciesCarolus Linnaeus Systema Naturae 1758
New order
• Modern classification systems are much more complicated having many levels of hierarchical organization
• Taxonomy (physical)• Phylogeny (genes)
Taxonomy• Kingdom metazoa/animall• Subkingdom • Phylum chordata/spinal chord• Subphylum vertebrata spinal column• Class mammalia/mammals• Subclass eutheria/placential• Order Primates • suborder anthropodae/all monkeys apes, humans• infraorder Catarhini/old world monkeys ,apes, humans• Superfamily Hominodea/apes and humans• Family Hominidae/ Human• subfamily • Genus Homo bipedal/same as • Specie sapiens sapiens wise man
