- This page details a lab on primate evolution from the Paleocene to the Miocene, focusing on diverse fossil specimens across six stations. Students analyze characteristics of various primate groups like Plesiadapiforms and Sivapithecus, enhancing understanding of primate phylogeny. It highlights key traits and notable fossils from the Oligocene and Miocene epochs, including Aegyptopithecus and Proconsul, while emphasizing ape adaptive radiation in warmer climates.
- 8.2: Fossil Primates (Worksheet)
- This page covers the evolution of primates throughout different geological epochs, starting with the Paleocene's plesiadapiforms and transitioning to the Eocene's true primates like omomyids and adapids. It highlights the Oligocene's anthropoid evolution, notably Aegyptopithecus, and discusses Miocene fossils such as Proconsul, Sivapithecus, and Gigantopithecus, emphasizing the diversity and adaptive changes in ancient primate species.
- 8.3: Prehistoric Primate Museum
- This page discusses the Prehistoric Primate Museum activity, which allows students to explore the virtual anthropology museum AnVRopomotron by Dr. Keith Chan. Objectives include identifying prehistoric primate models, examining traits, and inferring adaptations. Students use devices to complete a worksheet, fostering discussions on primate traits and evolution. It also offers tips for online adaptation, emphasizing the user-friendly navigation for those familiar with digital controls.
- 8.4: Prehistoric Primate Museum (Worksheet)
- This page details a virtual exploration of primate history, featuring interactive activities and discussions on fossil models and anatomical traits. Students navigate different environments and examine fossils like Archicebus and Proconsul. Learning objectives focus on identifying primate sizes, habitats, dietary habits, and morphological traits while promoting critical thinking about adaptations, fossilization, and evolutionary sequences.
- 8.5: Extant and Fossil Catarrhine Morphology
- This page explores the morphology of extant and fossil catarrhines, specifically comparing traits of baboons (Papio) and chimpanzees (Pan). It emphasizes identifying features related to sexual dimorphism and evolutionary traits by analyzing skulls and dental structures. Students will assess fossil specimens like Victoriapithecus and Aegyptopithecus to understand shared characteristics and classify ancestral relationships, fostering critical thinking in assessing evolutionary hypotheses.
- 8.6: Extant and Fossil Catarrhine Morphology (Worksheet)
- This page examines the cranial and dental differences between baboons (Papio) and chimpanzees (Pan), focusing on features like orbits and molar cusp patterns. It highlights sexual dimorphism in baboons, detailing male and female skull variations. The page also delves into the evolutionary history and ancestral traits of these primates, supported by fossil evidence, while prompting readers to consider the common characteristics and functions of morphological features across species.
