Chimpanzees
Which of the following is not a characteristic of pongo?
a) semi-solitary existence
b) young are dependent on mother for 8-9 years
c) resident males and females
d) hunt in groups
Pongo are semi-solitary species - which means they usually don’t hunt in groups.
These species are socially complex. They observe a strong lifelong bonding- particularly between mother and infant. They are very affectionate and at the same time, aggressive species.
Chimpanzees
Which of the following is not a characteristic of chimpanzees?
a) very affectionate and expressive (can communicate with each other using facial expression)
b) female dominated species
c) they hunt in groups
d) strong lifelong bonding
Chimpanzees are dominated by males while females migrate between groups. Whereas bonobos are dwarf chimpanzees, where females have the higher status.
So a bonobo derives its status from mum.
These species are less aggressive and sex serves purposes other than reproduction such as appeasement, affection, social status, erotic games, reconciliation, excitement and stress reduction.
Bonobos
True or false. Bonobos are able to use tools and communicate with each other using lexicograms and sign language.
True

a) Sahelanthropus tchadensis
b) Lucy
c) Orrorin tugenensis
d) Ardipithecus kadabba

Australopithecines
Which of the following are not characteristics of australopithecines?
a) obligate bipedalism
b) low degree of sexual dimorphism
c) prognathism
d) had large premolars/molars
b) low degree of bipedalism
Australopithecines had a high degree of sexual dimorphism.
This is known as the most complete hominin skeleton found in Hadar Ethiopia. It also shares a site of the first family with 9 adults and 4 children.
Lucy
This is the archaeological site where the first footprints were found. It had remnants of volcanic ash that showed evidence of 3 hominins walking around the area.
Additional question: which hominin species could it possibly be?
a) australopithecines
b) afarensis
c) sapiens
d) kenyanthropus platyops
Laetoli, Tanzania
b) afarensis - afarensis was the only hominin in this time period (3.6 mya)
This is known as the world’s oldest child.
a) Selam
b) Dikka
c) Lucy
d) Chadensis
a) Selam the Dikka Child (3 yr old girl)
This hypothesis states that big brains consume more calories because brains use a lot more energy.
Expensive Tissue Hypothesis
This was the first australopithecine/hominin found west of the Rift Valley.
a) Kenyanthropus platyops
b) Paranthropus aethiopicus
c) Australopithecine bahrelghazali
d) Australopithecine garhi
c) A. bahrelghazali
This hominin species is a gracile australopithecine known to have more homo-like body proportions. Also known as the Southern Ape Sunrise.
a) Paranthropus boisei
b) Australopithecine africanus
c) Australopithecine bahrelghazali
d) Australopithecine garhi
d) A. garhi
This hominin species is known to be contemporary with the first homo species. It was discovered in Olduvai Gorge and has a great degree of sexual dimorphism.
a) Paranthropus boisei
b) Paranthropus aethiopicus
c) Australopithecine bahrelghazali
d) Australopithecine garhi
a) P. boisei
This hominin species is known as the oldest species in Southern Africa and the first australopithecine to be found. It is also known as the Southern Ape from Africa/Taung Child.
a) Paranthropus boisei
b) Australopithecine africanus
c) Australopithecine bahrelghazali
d) Australopithecine garhi
b) A. africanus
This hominin species had body proportion similar to a chimpanzee and serves as evidence of facultative bipedalism.
Ardi
This hominin species was more derived than any other australopithecines. It showed evidence of a parabolic dental arch and bipedalism.
a) Australopithecine sediba
b) Australopithecine africanus
c) Australopithecine bahrelghazali
d) Australopithecine garhi
a) A. sediba
What is the first thing that changes in hominin evolution? Why?
Dentition; reveals changes in diet
This hominin species is known as the handy man.
a) Homo habilis
b) Homo rudolfensis

a) Ardi
b) Lucy
c) Turkana Boy
d) Chad
c) Turkana Boy
- Ardi => smallest, chimp-like skeleton ever found
- Lucy => most complete hominin skeleton
Which hominin species stayed in Africa?
a) Homo habilis
b) Homo rudolfensis
c) Homo ergaster
d) Homo sapien
c) H. ergaster
- H. erectus left Africa.
This states that a species descended from a common ancestor gradually diverge more and more in their morphology as they acquire unique adaptations.
Gradualism model of evolution
This states that a new species changes as it buds from parent species then changes little for the rest of its existence.
Punctuated equilibrium model of evolution
These constitute the oldest evidence of an essentially modern human-like foot anatomy, found in Northern Kenya. These suggests bipedalism - however, the footprints in Laetoli, Tanzania provide earlier evidence (dating to 3.6 mya) for bipedalism.
Ileret footprints.
