1. HOMINID EVOLUTION
Phylogenetic tree to show the place of the family Hominidae in the animal kingdom.

2. Human classification

4. Phylogenetic Tree of the family Hominidae:
Australopithecus & Homo
Chimpanzees
Gorillas
Orangutans
Gibbons
Tribe: Hominini
Subfamily: Homininae
Family: Hominidae
Super family: Hominoidea

5. Evidence that supports the idea of common ancestors for living hominids including humans:
1) Fossil evidence

8. 2) Genetic evidence: mitochondrial DNA

10. 3) Cultural evidence: tool making

13. List of characteristics that humans share with African apes: p243
Opposable thumb =
Hands and feet can grasp (prehensile) =

14. 3) Fingernails instead
of claws =
4) Binocular stereoscopic vision =

15. 5) 32 teeth in permanent heterodont dentition = heterodont means different teeth (molar, canine etc. see p243)
6) Single pair of mammary glands (breasts)

16. Tabulated anatomical differences between African apes and humans:
1) Permanently Bipedal (foramen magnum central, spine S-curved with short lower back and pelvic girdle short) .
1) Occasionally Bipedal (foramen magnum in back, spine C-curved with long lower back, pelvic girdle long narrow).
2) Larger brain size.
2) Smaller brain size.
3) Small teeth, equal size.
3) Small teeth, large canines.

17. Humans
African apes
4) No prognathis.
4) Pronounced prognathis.
5) Palate rounded shape.
5) Palate elongated rectangular shape.
6) Cranial ridges totally absent.
6) Cranial ridges still visible.
7) Brow ridges absent.
7) Brow ridges pronounced.

18. Foramen magnum positioning for Bipedalism
Gorilla
A. africanus
Human

19. Hip / Pelvis and leg structure for Bipedalism

20. Bipedalism leaves the hands free to hold food, young and protect self.
Allows field of view over tall grasses to protect against stalking predators.

29. Distribution of humans across the planet:
The Out of Africa hypothesis states that all modern humans originated in Africa.

30. Out – of – Africa theory

32. Lines of evidence that support the Out of Africa hypothesis:
1) Fossil record – fossil sites in:
a) The Great Rift Valley in East Africa (Kenya and Tanzania), Ethiopia p256
b) South Africa p256
2) Mitochondrial DNA p255

33. Bipedalism evidence:
Laetoli footprints discovered in 1978 by Mary Leaky at Laetoli in Tanzania.
3.6 million years old.
Made most likely by an australopithecene

41. P246 – 248 = Very good for studying developmental comparisons.
