![]() ![]() Station 2: (a) non-primate (cow or pig) skull with teeth, (b) dog skull with teeth, (c) monkey skull with teeth, and (d) human skull with teeth.Preservation should be good enough to see nails/claws. Station 1: (a) primate (e.g., monkey) articulated skeleton, and (b) non-primate (e.g., cat or dog) articulated skeleton.Materials include non-primate, nonhuman primate, and primate skulls and articulated skeletons. linked to the student worksheet to create a virtual lab.All skeletal materials should be labeled with cards/small labels with terms that match the student worksheets (e.g., Primate, Strepsirrhine). Before beginning this lab, the instructor should select skeletal materials, casts, or images of skeletal materials for students, and arrange them at various stations. ![]() and prehensile (grasping) hands and feet.differences in tooth morphology (reflects variable diets).flattened nails instead of, or in addition to, claws.reduced snout length (related to less reliance on smell).eye orbits with a postorbital bar or plate.a generalized skeletal structure for arboreal life.Thus, physical traits that help us distinguish primates from other mammals include: This ancestor may have had some depth perception, made possible by the overlapping visual fields of forward-facing eyes, and hands with the ability to manipulate objects. Primatologists believe the common ancestor of all living primates was an arboreal climber with prehensile extremities who relied on vision more than olfaction (smell). For example, most primates move about in trees by grasping with their feet and hands. This lab gives students the opportunity to observe characteristics of the skeleton that differentiates primates from other mammals and compare primates to one another.īefore beginning, students should consider the following conceptual questions: What can bones tell us about the animal to which they belonged? Specifically, what might the skeleton tell us about:īones can reflect the lifestyle of primates, and the characteristics they share are likely reflective of early primate ancestors. People belong to the zoological order Primates, which is one of the many orders within the class Mammalia. Station 6: Old World Monkeys and Hominoids.Station 3: Primate Suborders: Strepsirrhini and Haplorrhini.Station 2: Non-Primate and Primate Teeth and Skulls.Station 1: Primate Versus Non-Primate Postcrania.
