What are the differences between old world and new world primates?
New world (platyrrhine)
- flat nose
- Nostrils further apart and outward
Old world (cattarhine)

- big sharp canine teeth with a gap between canines and incisors
- are larger in size
- more terrestrial
What is the goal of GAP
The great ape project (GAP) is an international movement started in 1994. Its main purpose is to guarantee the basic rights to life, freedom and non- torture of the non- human great apes (chimpanzees, gorillas, orangatuns and bonobos)
Questions from slides - you need to find answer - What are the four major trends that differentiate hominids from hominids (describe in detail)
- Habitual bipedalism
Physical changes required for bipedalism - rotates foreman magnum, S lumbar curve and arch in foot, bowl- shaped pelvis and locking knee (knock kneed) and longer legs and a great toe in line - Dentition/ jaw changes
Facial projection decreases overall with reduce canine size and diastema. There is absence of canine honing complex and parabolic dental arcade. - Expanding, complex brain
The hominin brain capacity has increased through time but about 2mya the absolute and relative size of the brain increases - reasons? You will need to look this up notes just have reasons? With question mark after it - Tools and increasing cultural complexity
Earliest undisputed stone tools appear ca. 2.6 mya in Ethiopia. There were Oldowan stone tools and evidence for culture (teachers notes say advantages and who used them? But you have no notes to explain this)
Question from slide - What are the major genus groups of the early hominids
Notes just list superfamily
Lemuroidea (lemurs) Lorisoidea (lorises) Ceboidea (new world monkeys) Cercopithecoidea (old world monkeys) Hominoidea (apes and humans)
If she wants genus you will need to look this up
Question from slide - what are differences between robust and gracile species of authralopithecus
Later Australopithecus existed 3-1.5 mya they were divided into robust and gracile species based mostly on chewing
Robust line goes extinct
Should get more detail from your textbook I am guessing you missed this class as you have no notes that expand in teachers notes
Question from slides - Be able to identify what distinguishes genus homo from early hominins
Will need to find in notes
Earliest bipedal hominins were Australopiths e,g. Ardipithecus, Paranthropus and Australopithecus (7-1.5 mya)they had small cranial capacity, smaller canines and later around 3mya has slightly curved fingers and toes.
Early homo species appeared during 2.5-2mya and lived in Africa between 2.4 - 1.5 mya. Likely evolved from gracile australopiths and lived alongside robust australopiths - they had larger brains started by around 400-500 cm3
Highlighted question from slides - identify the tools and cultural behaviours associated with each homo species
What tools and cultural behaviours are associated with lower palaeolithic
At 2.6 - 1.5 mya there was the Oldowan stone took tradition
- associated with H. habilis
- percussion flaking, core and flaking technology
- choppers and scrapers
At 1.8 mya - 200,000 ya Acheulian stone tool
- associated with H. erectus
- soft hammer percussion
- bifacial handaxes , cleavers and scrapers
- culture - big game hunting and control of fire by 1.4 mya - they had campsites and Home based and cultural differences in Asia
Highlighted question from slides - identify the tools and cultural behaviours associated with each homo species
What tools and cultures are associated with Homo erectus
- 8 mya - 400,000 ya
- may have been the first to leave Africa
- little change for over 1 million years
- cranial capacity 1000 cm3
- pentagonal skull and smaller teeth
- endurance runners
- likely ancestor to sapiens through archaic Homo sapiens
- soft hammer percussion
- bifacial handaxes, cleavers and scrapers
Highlighted question from slides - identify the tools and cultural behaviours associated with each homo species
What tools and cultures are associated with Homo neandertalensis
230,000 - 27,000 ya
- were short and more robust with elongated skull and occipital bun (ave 1500cm3). There was some interbreeding between sapiens and Neanderthals outside of Africa.
- the mousterian stone tool culture was associated with H. neandertalnsus also used Levalloisian method of tools with tortoise shaped cores and produces standard size flakes
- the mousterian culture were of skilled hunters that killed bison, horses and deer. They used caves and rock shelters as homesites (cave man). There was evidence for ritual behaviours from burial sites
Highlighted question from slides - identify the tools and cultural behaviours associated with each homo species
What tools and cultures are associated with Homo sapiens
200,000 ya - now
- anatomically modern humans that have moved across the globe - cranial capacity around 1350cm3
During upper palaeolithic cultures (40,000 - 12.000 BP)
- blades are flakes that are at least 2:1 (length:width) with parallel sides
- pressure flaking
- had trade and diverse art (including cave art)
Highlighted questions from slides
What are the two models for what happened to the other hominins after modern humans appear
- Replacement/Single origin theory - in this theory Homo sapiens evolve in Africa. They leave Africa around 100,000 BP (before present) and replace others. Human variation is only recent in this theory.
- Multiregional theory/Regional continuity - in this theory each population around the world evolves in place from existing Homo erectus groups who left Africa around 1 mya. Thus requires gene flow and human variation would be ancient.
See textbook pages 138-139
Highlighted questions from slides
Know the two models of how the New Works was Peoples including dates
Notes only has following
- where did the Paleo-Indians come from?
- Siberian origins (blood, incisors, culture)
- Comparative linguistics (3 migrations)
- Clovis 1st (12,000) vs pre-Clovis (33,000 BP)
So you need to look up the two models and dates
Highlighted question from slides -
What is the importance of late Miocene?
23-5mya was the Age of the Apes
11-5 mya there is a sparse hominoid fossil record
In later Miocene there is a hominin/hominid line (Homo and Australopiths only) splits from hominoid line (between 10-5 mya)
Highlighted question from slides - for each epoch be aware of major events (do not need to know dates)
Palaeocene - extinctions and mammalian adaptation be radiation leads to evolution of diverse new species from a single ancestral species that occupy open habitats. Time of arboreal adaptation vs visual predation theory of primate emergence
Eocene - first definite primates appear - appearance of anthropoids (ancestors to apes, monkeys and humans)
Oligocene - emergence of hominoids (Fayun Depression fossils)
Miocene - Age of the Apes and time of split of hominin/ hominid line
Highlighted question from slides -
Explain in depth the skin color adaptation
Nothing in notes you need to look this up
Highlighted question from slides - Describe how different groups have adapted to different climates?
Not in notes you gave me - you will need to find answer
Highlighted question from slides - what is the main difference between adaptation and acclimatization
Nothing in notes you need to find answer
Highlighted question from notes - explain how physical adaptations may have cultural agents (provide examples)
Says from discussion in class there is nothing in your notes you will have to find answers - suggest watch Becoming Human video part 1 as well for exam
Highlighted questions from slides - What are the three foundation ideas of evolutionary theory
- transformational evolution (change)
- uniformitarianism (time)
- competition (pressure)
Highlighted questions from slides - What are the three principles of natural selection
Natural selection is a two step process of how descent with modification takes place
1. variation in all individuals in a species (e.g. recombination, mutation)
2. heritability of traits
3. differential reproductive success = adaptive individuals often win competitions for resources; they survive and/or reproduce more, with their offspring likely to inherit favourable traits
No notes on this topic
Highlighted questions from slides - is natural selection working towards a perfect organism?
No there is no perfect organism
• traits that give an advantage in survival and reproduction should increase over time
• adaptive, neutral and maladaptive traits in a given environment
• directional, normalizing, balancing selection
• HMS video clip (on BBL)
• the role of sexual selection
Highlighted questions from slides - explain the concept of Mendelian genetics
- homozygous, heterozygous
- dominant alleles are expressed if present
- recessive alleles are carried but not expressed unless in homozygous form
- genotype is the total genetic information of an organism, including recessive alleles
- phenotype is the portion of genetic information that is expressed and observed
- principle of segregation means an individual gets one gene for each trait from each parent
- principle of independent assortment means that alleles separate randomly into gametes and are not necessarily linked to other alleles
Highlighted question from slides - What are the patterns in genetic variation?
- clinal (continuous) variation is when a trait gradually changes (+/-) over a geographic area
- discontinuous variation is when traits appear in ‘patches’ with little/no gradation between areas
Highlighted questions from slides - why is generics not simply a matter of gene=trait?
- polygeny = many genes are responsible for one trait
- pleiotropy =one gene affects more than one trait
- norm of reaction = table or graph that displays the possible phenotypic outcomes for a genotype in different environments
- ‘environment’ + genes + age + “noise”
