Verified Answers
Q1: Family Hominidae
A: Includes the great apes, humans, and humanlike ancestors
Q2: Tribe Hominini
A: "Hominins" i.e. modern humans and our obligate biped ancestors
Q3: Protohominin
A: Earliest members of the hominid lineage barely represented in the fossil record
Structure and especially behavior are reconstructed
Q4: Two Views on the Evolution of Humankind (Early 20th Century)
A: "Locomotion First" & "Brains-First" (Large Brains)
Q5: "Locomotion First"
A: Ape -> Bipedal Ape -> Intelligent Bipedal Ape (Large Brain) -> Human
Q6: "Brains-First" (Large Brains)
A: Ape -> Intelligent Ape -> Bipedal Intelligent Ape -> Human
Q7: Piltdown Man
A: Piltdown Discovery 1912
Charles Dawson (1846-1916) lawyer, amateur geologist
Fossil remains first unearthed in
Sussex gravel pit circa 1908
Chipper: Piltdown Gravels Mascot
Q8: "Dawson's Dawn Man"
A: Eoanthropus dawsoni Woodward 1912
Woodward's reconstruction - cranial capacity of 1070 cm ^3
Several "camps" did not accept authenticity, or rather, the "association" of skull fragments
and jaw
Others did not accept Woodward's reconstruction
Q9: The Piltdown Hoax
A: 1953 jaw and cranial fragments were not from the same individual
Setback of some 40+ years for paleoanthropology
Deemed the "missing link"
Brains before bipedalism
, Supported a more "local" evolutionary scenario
Completely undermined faith in the anthropology discipline
Led to a dry up in funding for future projects
Money dried up, people's reputations went down the drain
Q10: Brain Size
A: Apes = small
Humans = very large
Q11: Bipedalism
A: Bipedal posture
Bipedal locomotion
Habitual or "obligate" bipedalism = Form of locomotion practiced by hominins
Some mammals adopt bipedal postures
Q12: Bipedal Macaque
A: Israeli zoo, Safari Park
Natasha, a five-year-old macaque
She almost died of a severe stomach flu and then started walking bipedally!
Q13: Foramen Magnum Position
A: Positioned further forward (anteriorly) under the skull
Big hole at base of skull
Q14: The spine of hominins has two distinctive curves
A: indicates bipedalism
Q15: Paleontologists find a fossil ape with long arms. What type of
environment can they infer it inhabited?
A: woodland
Q16: Studies of temperatures during the Cenozoic era suggest that
temperatures have ________ over time.
A: fluctuated, sometimes greatly
Q17: The study of what happens to an organism's remains after
death is
A: taphonomy
Q18: An index fossil is
A: a fossil used to categorize a stratigraphic layer
