Objective: Who’s Who Learn the taxonomy and classification associated with: S trepsirrhini Lemurs, Lorises, Galagos H aplorrhini Tarsiers “New World” Monkeys “Old World” Monkeys Apes: “Lesser” & “Greater”
Why Taxonomy is not Terrible! Taxonomy is a system —which means once you get the system, you have a platform for the information on the primates Primates are a great way to learn the system b/c they have a lot of fascinating traits—which helps in memorization of the information The test is multiple choice —that means I have to spell things correctly, you don’t To sum up: Taxonomy is learning a system, and then putting the right pieces of information in the right places of the system
Taxonomy The scientific naming of categories of organisms “Hierarchical organizing system based on similarities of traits due to common ancestry” (homologies) p. 49 Strier Commonly used traits include morphology, genetics, behavior, pelage, vocalizations Taxonomy is used to distinguish broader categories of organisms (plural taxa , singular taxon ). For example, taxonomy is useful for grouping similar Subfamilies ( taxa ) together in a Family (taxon) , or grouping similar species ( taxa ) into a Genus (taxon)
A Big Problem: Disagreement over what is a species Lynch Alfaro et al 2012 What constitutes a “true” species is often blurry “Lumpers” (emphasize similarities) vs “Splitters”(emphasize variation) About 500 species of primates today (p. 51 Strier). But this number is in flux; in the 4 th edition of Strier’s texbook, primatologists thought there were 240 species of primates Even among the well-studied capuchin monkeys researchers differ about how many species exist and how to classify them
