Discuss the differences between the Turkana Boy and the Dmanisi fossils. Indicate the importance of those differences. - What major hominin fossil discoveries were made in 1984 near Lake Tukana in northern Kenya? State the implications for human evolution. - Explain how changes in the teeth of humans are related to the growth and development of humans and chimpanzees. How can you calculate the age of a fossil from the teeth?

Which of the following statements about hominins is FALSE?     Each hominin species on Earth was directly descended from the species that preceded it     Multiple hominin species lived at the same time     The genus homo arose about 2.5 million years ago     We have now discovered a vast number of hominin fossils, allowing us to trace the evolution of humans fairly well

All of these characteristics of P. aethiopicus suggest that it may represent an evolutionary connection between A. afarensis and P. boisei, EXCEPT: Pneumatized mastoid region Brain size of 410 cc Compound temporal-nuchal crest Large posterior an anterior dentition Sagittal crest that extends from posterior to anterior on the cranial vault

50. Which hominid remains show extensive evidence for having used their teeth as tools?   Orrorin tugenensis   Archaic Homo sapiens   Homo sapiens neanderthalensis   Homo habilis   Homo erectus

Evidence for biocultural evolution during the Upper Pleistocene may exist in the form of craniofacial morphological differences between premodern humans and modern humans because, as one interpretation mentioned in your text suggests… Group of answer choices deep concentration on the creation of cave art murals resulted in the selection for more gracile craniofacial morphology in modern humans hunter gatherers used landscape surveying methods to hunt and gather resources, a practice that required long periods of squinting resulting in supraorbital browridge muscle robusticity frequent spiritual rituals focused around chanting practices resulted in enlarged craniofacial muscle attachments basket weaving techniques required the use of the teeth as a clamp to temporarily hold the sinew technological innovations assisting with food processing resulted in anatomically modern humans not needing large teeth and facial muscles to chew and process their foods

The legend on the bottom left reflects three basic conditions that describe the character that pertains to body covering (or integument). The conditions that pertain to the specific taxa at the top of the tree are shown by the numbers. Dinosauria Trace the integument character along the tree (you may want draw it out on a separate sheet of paper). Once you have done that step, consider the ancestor of all dinsoaurs. What character condition did you get? Crocodiles Pterosauria O (ex. Pteroda O (ex. Stegosaurus) Kul indadromeus Psaurus (ex.…

What are HOX genes' role in lobe-finned fish to limbed tetrapod evolutionary transition?  -Please explain "how" HOX genes have influenced these limbs/appendages from an evolutionary standpoint. Thank you.

From the following 5 characters, characterise at least 2 key features of the dinosaur teeth provided and use it to determine whether each dinosaur is a carnivore or a herbivore. Write the supporting characteristics out in full but also give the associated character number and its state e.g., denticles absent, 4(0). 1. Tooth shape: (0) Cylindrical [inconclusive] (1) Conical [carnivore] (2) Low and broad [herbivore] 2. Tooth curvature: (0) Straight [inconclusive] (1) Recurved [carnivore] 3. Tooth top: (0) Flat [herbivore] (1) Single sharp cusp [carnivore] (2) Multiple sharp cusp [herbivore] (3) Single rounded cusp [inconclusive] 4. Denticles (serrations): (0) Absent [inconclusive] (1) 'Coarse', few in number and very large [herbivore] (2) 'Fine', many and relatively small [carnivore] 5. Constriction between top and base of tooth (0) Absent or weak. Constriction occupies >85% of largest width [inconclusive] (1) Well-developed. Construction occupying <85% of largest width [herbivore]…
