- Are there any major differences between new world monkey skulls and old world monkey skulls? Take into account their anatomy, structure, size, and dentition.Label the four parts that make up the cranial buttressing system of Homo erectus (where are they located): supraorbital torus, sagittal keel, angular torus, occipital torus H. habilis skulls do not have a cranial buttressing system. Different skull functions show species developments. What different activities did H. erectus engage in that H. habilis did not? Where was the Nariokotome skeleton found? How old is the fossil? (in terms of millions of years ago) How old was this individual at death? (actual and modern equivalent) What sex was this individual? What have we learned about the Homo erectus species in general by studying the fossils of this particular individual? Go on to the next page in this assignment STATION 4: Compare the following forms of H. erectus to get an idea of the diversity present. Date range Cranial capacity? (cc) Where found? Supraorbital torus? (S/M/L) Overall robusticity (S/M/L) Sex? (male or female) Age? (juvenile or adult) Dmanisi 5 (Early H. erectus)…Compare the 3D skulls of H. heidelbergensis with H. erectus. Detail at least three cranial traits of H. erectus and how they are different or similar to H. heidelbergensis Homo heidelbergensis skull: https://skfb.ly/osTD9 Homo erectus skull: https://skfb.ly/orp9I
- Which of the following statements is true when it comes to using skeletal remains to determine the biological sex of the individual? O identifying the sex of skeletal remains is easy and 100 certain that a skeleton is either male or female O Modern scientists now label more skeleton remains as indeterminate" which reflects the variability and overlap in features between the sexes, but still suggests a binary mindset O The finding that there are about 12% more male skeletons than female skeletons at archeological sites reflects the likelihood of skeleton preservation rather than bias and assumptions in assigning sex to skeletal remains O While other parts of the skeleton are less clear, pelvis ac blades that flare are clear indications the skeleton was of a female.Diapsids possess a single temporal opening in their skulls true false Other:Using the 3-D models and list of cranial traits, describe the general cranial morphology for H. neanderthalensis. Be sure to describe at least three cranial traits of H. neanderthalensis (i.e., skull size/morphology, prognathism, occipital anatomy, forehead, or dentition). (Minimum of 2 complete sentences.)
