HUMAN EVOLUTION TIMELINE
WHAT IS HUMAN EVOLUTION
 Human evolution is the evolutionary process that leads to the emergence of
anatomically modern humans. Human evolution is the lengthy process of
change by which people originated from apelike ancestors. Scientific evidence
shows that the physical and behavioural traits shared by all people originated
from apelike ancestors and evolved over a period of approximately six million
years.
 Humans are primates. Physical and genetic similarities show that the modern
human species, Homo sapiens, has a very close relationship to another group of
primate species, the apes. Humans and the great apes (large apes) of Africa --
chimpanzees (including bonobos, or so-called pygmy chimpanzees) and
gorillas -- share a common ancestor that lived between 8 and 6 million years
ago..
 Mainly focus on the genus HOMO
HISTORY OF HUMAN EVOLUTION
 T.H. HUXLEY (1863) made first attempt to mans origin in his book Mans
Place In Nature and visualized apes the closest human relatives.
 Later in 1871, Charles Darwin advocated his idea about mans ancestry in his
book The Descent With Man and propounded origin of man from apes First
fossils of human ancestors were described by Eugene Dobois in 1880s.
 This includes skull cap, lower law jaw fragments and Thigh bones from East
Indies. Most pre human fossils were discovered and studied from 1920
onwards.
 The main contributors for the study of human evolution were Raymond Dart
(1920s), Davidson Black (1934), L.S.B Leakey and Mary Leakey and their son
Richard.

GREAT APES
DRYOPETHECUS
 They lived during the MIOCENE
Epoch
 Roughly 10-5 Mya
 They resembled more like monkeys
 They were branchiators
 They were found in eastern Africa
RAMAPETHECUS
 They were also present in the
MIOCENE Epoch
 They were present roughly 12.5 Mya
 Resembles more like Apes
 They dwelled on both trees and land
 Their fossils were found in the shivalik
hills
AUSTRALOPITHECUS
 It is a extinct genus which evolved in the eastern Africa around 4 Mya and then started
spreading throughout the continent
 Many species of the australopithicus evolved eg: A afrenesis, A africanus , A anamensis,
A garhi, A sedbia
 They played the most significant role in human evolution as the genus homo is derived
from australopithecus from some time after 2.8 mya
 One of the Australopith species went onto become the first homo genus in africa some
2.5 mya
 Their brain capacity was roughly ~ 490-600cc
 They were largely frugivorous
AUSTRALOPITHECUS
 Ape-man.
 Connecting link between man and ape.
 Australopithecus africanus is a
common fossil.
HUMAN CHARACTERS OF AUSTRALOPITHECUS
 Erect posture with 4 ft height.
 Bipedal locomotion.
 Basin-like pelvic girdle.
 Dentition like man.
 Hands used for non-locomontory functions.
HOMO HABILIS
They were present during the
Pleistocene epoch and lived during
2.8 to 1.5 Mya
 It is the least similar to modern
humans of all species in the genus
homo
 It was short in stature(4ft 3inch)
and had long disproportional arms
 Its brain capacity was ~ 550-
687cc
 There feeding habits varied from
fruits, leafs and occasionally
eating small lizards
 Homo habilis is thought to have
mastered the Lower Palaeolithic
Olduwan tool set which used stone
flakes. H. habilis used these stones
to butcher animals and to skin the
animals .
HOMO ERECTUS
 First true man.
 Primitive man.
 Connecting link between ape man and
modern man.
 Also called java man.
 Lived in java and Peking.
HOMO SAPIENS
 Homo sapiens have lighter skeletons
than those humans who came before
them
 Large brains: approximately 1300
cubic centimetres
 Thin walled, high vaulted skull with a
forehead almost perpendicular to the
ground
 The main differences between homo
sapiens sapiens, and homo sapiens is
that we have more brains and brawn
