What evidence is found in the fossil record that shows that early ancestors of humans walked upright and used bipedal locomotion? Select all that apply.   a On the bottom of the skull, there is a place where the backbone attaches. b Fossilized bones of the hip and pelvis are shorter in height. c The feet evolved five toes from three toes. d The backbone was attached to the back of the skull.

List three characteristics that distinguish Homo sapiens from premodern Homo Homo sapiens have a mental eminence Homo sapiens have a receding chin Homo sapiens have a prognathic midface Homo sapiens have a rounded cranial vault Homo sapiens have a vertical forehead O Homo sapiens have a juxtamastoid crest

Take a look at the skulls out on display Define and describe the differences between the groupso Australopithecuso Homo habiliso Homo erectuso Homo heidelbergensis How are the non-human primates similar? How do they fit into the tree? Which examples do wehave out?

Fossil Cranium #1 is MOST LIKELY This is FOSSIL #1 below D. Top views Frontal views This is FOSSIL #2 below lockact FOSSIL #3 is below, O Homo sapiens O I don't know but it can't be the others O Homo neanderthalensis O Paranthropus robustus (which our book calls Australopithecus robustus)

Which of the following is NOT true about the Homo floresiensis fossil remains? Group of answer choices Were likely afflicted with a severe growth defects May have evolved from ancestors that left Africa before Homo erectus They were recovered in Liang Bua Cave on the island of Flores, east of Java have been affectionately named "the Hobbits" Were contemporary with modern humans 25 kya

Figure 15.33 Which of the following statements about common features of chordates is true? a. The dorsal hollow nerve cord is part of the chordate central nervous system. b. In vertebrate fishes, the pharyngeal slits become the gills. c. Humans are not chordates because humans do not have a tail. d. Vertebrates do not have a notochord at any point in their development; instead, they have a vertebral column.

Mammals have a particularly good sense of earing thanks to their inner ear which includes three tiny bones. Reptiles, in contrast, have a single inner ear bone. The lower jaw of reptiles is composed of multiple bones while the lower jaw of mammals is a single bone. Fossil and developmental evidence indicate that the inner ear bones of mammals evolved from lower jawbones. This suggests that the inner ear bones of mammals are   1. an analogy 2. an exaptation 3. a living fossil 4. a transitional trait 5. a vestigial structure

Australiopithicus was one of many hominid primates that lived during the late Neogene. This particular species of ape was of interest to researchers because it was the first to: Use fire O Use language O Use tools Walk upright

Nothartcus is an extinct early primate that lived around 50 million years ago. With long curved fingers and naisl instead of claws, it was one of the earliest hands that looked like ours. True or false?
