Question: list at least three factors essential to the study of primate ecology

title: Primate
text: Thus , the members of the two sets of groups , and hence names , do not match , which causes problems in relating scientific names to common ( usually traditional ) names . Consider the superfamily Hominoidea : In terms of the common names on the right , this group consists of apes and humans and there is no single common name for all the members of the group . One remedy is to create a new common name , in this case `` hominoids '' . Another possibility is to expand the use of one of the traditional names . For example , in his 2005 book , the vertebrate palaeontologist Benton wrote , `` The apes , Hominoidea , today include the gibbons and orang - utan ... the gorilla and chimpanzee ... and humans '' ; thereby Benton was using `` apes '' to mean `` hominoids '' . In that case , the group heretofore called `` apes '' must now be identified as the `` non-human apes '' .
