BIOLOGICAL EVOLUTION OF MAN
3
As humans, how will you show respect to each
stages of man and with their contribution in the
society?
4
EVOLUTION
It refers to the changes that occur in a
population over time. In this definition,
population refers to the group of the same
species that share a specific location and
habitat.
5
HOW EVOLUTION TAKES PLACE?
6

• Evolution takes place because there are
  variations in every species of organisms
• It is because of scarcity in supplies and the
  growing population tend to compete to the limited
  resources
• This competition may eventually result in deaths
  for some individuals while others may be able to
  preserve themselves and continue their existence

Why did primate descend from trees and began
living in the ground?
17
THREE PROBLEMS

• Knuckle Walking It is roaming around using his
  hands in walking which made it difficult for him
  to do other tasks. (Bipedal)
• Predators - Abound in the savannas and this was a
  grave concern for a primate, especially during
  sleeping time. (Shelter)
• Plants - Being scattered over a large expanse of
  land in the savannas than in the forest lands.

THE TWO CATEGORIES OF HOMINIDS
19

• Australopithecus
• Homo

20

• Australopithecus are also known as the Southern
  Apes
• It was discovered by Raymond Dart in South Africa
  in 1925
• They tended to have longer arms that seemed
  well-suited to climbing
• Their facial features looked more ape-like than
  human, with sloping faces, and jutting jaws.
• Some of the remains that were unearthed include
  Australopithecus Africanus, Australopithecus
  Robustus, and Australopithecus Afarensis.

21
Lucy was the famous fossil of Australopithecus
Afarensis. She stood four feet tall in between
19-21 years old. She was a Bipedal, had hands
similar to that of a human and a brain comparable
to the size of Chimpanzee.

HOMO HABILIS (ABLE MAN)
24

• They are bipedal
• They possessed an opposable thumb that
  facilitated efficient handling of things and
  creating tools
• They also have smaller teeth and jaws and more
  modern looking feet.

HOMO ERECTUS
27

• Homo Erectus possessed much larger brain, stood
  at around feet and 6 inches.
• They are also the first human species to have a
  wide and fleshy nose.
• The face was flat and the skull had prominent
  ridges over the brow and they had shorter arms.
• Their longer legs were better suited to running
  and walking long distances.

HOMO SAPIENS
31

• They were also called as Wise or Intelligent Man
  because they discovered sophisticated control of
  fire.
• Cave art also began to be produced about 40,000
  years ago in Europe and Australia.
• Burials in the past were infrequent and very
  simple prior to 40,000 years ago.
• Modern Humans are called Homo Sapiens Sapiens
  because of their ability to speak and communicate.

32
OVER TIME, WHAT ARE THE CHARACTERISTICS OF HUMANS
THAT HAVE EVOLVED?
33

• Human brains are larger and more complex.
• People have elaborate forms of communication and
  culture.
• People habitually walk upright, can speak, and
  can manipulate very small objects.
