1) Which characteristics were present in the earliest
hominins?
a) communication through speech
b) modification of stone to make tools
c) bipedal locomotion
d) increased brain size
2) Which skeletal characteristic is not associated with the hominin
evolution of bipedalism?
a) a foramen magnum on the bottom of the skull
b) a shortened pelvis
c) a varus (outwardly pointed) knee
d) an S-shaped spine
3) Which dental characteristic is not a hominin adaptation?
a) non-honing chewing
b) small, blunt canines
c) loss of the diastema
d) thin tooth enamel
4) Pre-australopiths are distinguished from apes by both bipedalism
and by:
a) adaptation for a savanna or grassland environment
b) complete loss of adaptations for arboreal locomotion
c) an intermediate or complete loss of the honing complex
d) a significantly enlarged cranial capacity
5) How did the australopith lineage leading to Homo adapt its diet
to prevent extinction?
a) consuming mostly low-quality vegetation
b) relying on tough, hard foods
c) focusing on a narrow range of foods
d) developing a flexible and generalized diet
1) Which characteristics were present in the earliest hominins?
Answer: (C) Bipedal locomotion.
From the homin fossils, it is evident of the presence of first human traits are bipedal walking which is a form of terrestrial locomotion where movement is done through two rear limbs or legs.
2. Which skeletal characteristic is not associated with the hominin evolution of bipedalism?
Answer: (C) a varus (outwardly pointed) knee.
Characterized by tibiofemoral structural progression due to dynamic alignment.
3) Which dental characteristic is not a hominin adaptation?
Answer: (D) thin tooth enamel.
Homins have short blunt canies and loss of diastema which is a gap between tooth. Non-honing chewing in homins have small, non-projecting canines which are not sharp against others.
4. Pre-australopiths are distinguished from apes by both bipedalism and by:
Answer: (C) an intermediate or complete loss of the honing complex.
Also called as basal hominin and earliest known homin is Sahelanthropus tchadensis.
5) How did the australopith lineage leading to Homo adapt its diet
to prevent extinction?
Answer: (D) developing a flexible and generalized diet.
