Introduction
Humans are primates and share a common ancestry with other modern primates some time in the recent past (in an evolutionary sense). The more advanced primates exhibit many physical characteristics and behaviours that are similar to humans, but at the same time there are fundamental differences between the apes and those that we would call Hominid.
Humans are a very much part of a consistency and change theme. The changing relationships of humans with their environment, which started when human ancestors were 'forced' out of the trees and compelled to take up an open plains existence, has been associated with considerable biological and cultural change.

1. # Define the term 'Primate' and list the identifying characteristics that all primates have in common
BZ pg General Primate Characteristics
Handout: Apes vs Us (use links below to fill in table)
2. # Describe the classification of the Order Primates into the following groups with examples:
a.Prosimians b.Tarsiers c. New World Monkeys d. Old World Monkeys e. Apes f. Hominins (Humans)
3. Describe the likely origin of the primates from a common ancestor 70 million years ago
BZ pg Primate groups, Primate Classification
Video: NOVA First primates
3# Describe the primate distinguishing characteristics that identifies each of these as a distinctly different group from other mammals.
Take into account the following features:
a. Physical dentition, limb structure, tail presence/absence tail function, facial structure, extent of bifocal and colour vision, degree of development of olfactory organs, snout and nostril structure.
b. Behavioural communication, social behaviour, locomotion, behaviour towards young.
c. Diet, habitat,

4. Define the terms hominid and hominin. Describe the anatomical and behavioral traits that are unique to humans. Describe the selection pressures and benefits of reduction in body hair and the adoption of bipedalism as the mode of locomotion.
BZ pg Hominoids and Hominins

5. Describe the features that identify the genus Australopithecus and Paranthropus. Describe the known anatomical features and possible niche differences of each species:
Australopithecus afarensis
Paranthropus boisei (also known as Australopithecus boisei)
Paranthropus robustus (aka Australopithecus robustus)

6. Describe the theory of continental drift theory and explain how this influenced climate patterns over the last 70 million years. Relate these changes of climatic zones to alterations in habitats exploited by the primates, changes in zones of tundra, temperate forests, savannah, tropical forests).
BZ pg Continental Drift and Evolution (in Previous chapter of Biozone)
7. Clearly define the characteristics which are unique to the genus Homo. Describe the biological and cultural evolution of the various species belonging to the genus:
Homo habilis
Homo erectus
Homo sapiens (archaic)
Homo sapiens neanderthalensis (Neanderthal)
Homo sapiens sapiens (modern)
Player Cards (refer to BZ Hominin data sheets)
By the end of 5, 6 and 7 you should be able to:
8. Describe the trends of biological evolution with respect to skeletal changes linked to bipedalism. Trends to include changes in: height, skull (foramen magnum etc), spine, pelvis, legs, knee, foot, toes, forelimb length. To include comparison with a non-human ape.
BZ pg Lucy
9 # Describe how the fossil evidence for Ardipithecus ramidus has changed our view on the evolution of bipedalism
BZ pg Ardipithecus ramidus
10. Describe the trends of biological evolution with respect to changes in manipulative ability of the hand. Trends are to include changes in thumb length (which resulted in more effective opposability),, finger shape/ length and dexterity. To include comparison with a non-human ape.

11# Define the terms: biological evolution ( as the transmission of factors by way of genes) and cultural evolution (as the transmission of ideas, beliefs, etc. outside the genes).
12. Distinguish between cultural evolution and biological evolution. Define the term cultural evolution as behaviour patterns passed on via learning and communication (viz use of tools, fire, clothing, beliefs).
Biological evolution is the result of natural selection acting upon whole populations over many generations. Biological evolution relies on mutations as a source of new characteristics and involves much longer time periods.
Cultural Evolution is any learnt behaviour (knowledge, attitudes, customs and ideas) Cultural evolution is passed from one generation to the next by learning. It is very fast compared to biological evolution and can happen within a generation or lifetime.
BZ pg Cultural Evolution
Describe the development of successive cultures over the last 3 million years:
1. Palaeolithic (Old Stone Age)
2. Mesolithic (Middle Stone Age)
3. Neolithic (New Stone Age)
4. Copper Age
5. Bronze Age
6. Iron Age
BZ pg Mesolithic Culture
13. Identify the various tool cultures (Oldowan, Acheulian, Mousterian, and Upper Palaeolithic) and the development of abstract thought- expressed in the form of art (e.g. cave paintings) and spiritual practices.
BZ pg Palaeolithic Tool Cultures, Palaeolithic Tool Use, Art and Spirituality
HO Cultural Evolution (complete associated questions)
14. Describe trends in human cultural evolution between hominins with respect to methods of acquiring food. Trends to include: change from gathering to hunting, domestication of plants and animals.
BZ pg Neolithic Culture
15. Describe trends in human cultural evolution between hominins with respect shelter and comfort.
16 Describe the trends of biological evolution with respect to changes in skull and endocranial features.
Trends to include changes in:
· the size of the: brain, zygomatic arches, forehead, mandible, Broca’s area, Wernicke’s area
· the prominence of the: brow ridge, chin
· the degree of prognathism, facial angle
· dentition (palate shape, diastema presence and size, size of teeth, enamel thickness).
To include comparison with a non-human ape.

17. Describe trends in human cultural evolution between hominins with respect to abstract thought.
Abstract thought - expressed in the form of art (e.g. cave paintings) and spiritual practices.
