Title: Primate to Human


1
Primate to Human
  • From simple to complex!

2
Primates
  • First primates evolved about 50 mya!
  • Two features of the primates
  • Opposable thumbs allow for grasping
  • Forward orientation of the eyes allows for
    binocular vision which permits depth perception

3
Early primates
  • Early primates are very similar to the prosimians
    of today!
  • Most likely nocturnal night active!

4
About 36 mya, primates diversified and became
diurnal.
5
Early Hominids
  • Primates that walk up right on 2 legs - Bipedal.
  • Early hominids led to the evolution of humans.
  • Hominids first appeared about 5-7 mya.

6
Australopithecines
  • The earliest hominids are known as
    Australopithecines.
  • Most famous fossil remains of this genus is LUCY!

7
Lucy vs. the Apes
  • Lucys brain had a slightly greater volume
  • Lucy had a S- shaped spine.
  • Lucys arms are shorter than legs.
  • Lucys bowl shaped pelvis upright walking
  • Lucys femurs angled inward carry body weight.

8
Approximately 3 mya Australopithecines began to
diverge!
Went extinct
Became Humans
9
Genus Homo
  • First appeared 2 mya!
  • Discovered near Australopithecine fossil site

10
Homo habilis
  • Tools have been found scattered amongst the
    fossils of this early man.
  • Homo man habilis handy
  • They stood about 4 ft tall.
  • Survived for about 500,000 years before going
    extinct.

11
Homo erectus
  • Larger than H. habilis about 5 ft tall.
  • Had a large brain.
  • Tended to live in groups of 20-50 members.

12
Homo erectus
  • Hunted large animals.
  • Used fire.
  • Made both stone and bone tools.
  • Went extinct 200,000 years ago.

13
Homo sapien
  • Homo man sapien wise
  • Fossils of this species first appeared in Europe
    about 130,000 years ago
  • These early H. sapiens were known as Neanderthals.

14
Neanderthals
  • Slightly larger brain than modern humans.
  • Skulls were massive.
  • Cared for their sick.
  • Buried their dead ? left artifacts with the dead

15
Why is burying the dead significant for the study
of human evolution?
16
Modern Homo sapiens
  • H. sapiens appeared about 34,000 years ago.
  • Typically they were hunters and gatherers.
  • Complex patterns of social organization.

18
Modern H. sapiens
  • Developed the ability to use tools effectively.
  • Use written language that permits concepts to be
    passed from generation to generation.

19
Modern H. sapiens
  • Developed abstract thinking.
  • Development of culture gave way to be able to
    change our environment to suit our needs!
