Human evolution Meet your ancestors!
ORIGIN AND EVOLUTION OF MAN • About 15 mya, primates called Dryopithecus and Ramapithecus were existing. • They were hairy and walked like gorillas and chimpanzees. • Ramapithecus was more man-like while Dryopithecus was more ape-like. • Few fossils of man-like bones have been discovered in Ethiopia and Tanzania
dryopithecus • Hairy ,Walked like gorilla,chimpangees
Early Great Apes Dryopithecusafricans Left the trees ca. 20 million years ago Bipedalism by at least 6 Ma .arms and legs of same length.
Ramapithecus(man like) Jaws ,teeth like humans Could walk like errct on its hind feet Walked upright
Australopithecus1st ape man • Lived in E.arican grass land • 2 mya • Hunted with stone weapons but ate fruits • Errect posture • Bipedal locomotion
australopithecus Brain capacity=600 cc
Australopithecines probably fed in forested areas and would emerge into more open grasslands to scavenge and also grub for roots and tubers.
Homo habilis Homo habilis which lived from 2.5 million years ago until 1.6 million years ago, Bipedal locomotion Errect did not eat meat Brain capacity 650-800 cc
It is believed that Homo habilis were the first hominids to create and use tools.
Homo erectus Discovered in java. 1.5 mya Brain capacity 900 cc Ate meat
Historians believe that Homo erectus began as gatherers but advanced over many generations into hunters. • With the discovery of fire, Homo erectus became even more adept at survival.
Homo erectus which lived from 1.8 million years ago to 100,000 years ago, and
Homo sapianens neanderthalensis • 1,00,000 to 40,000 yrs. • Brain 1400 cc • Walked upright • Hides to protect their body • Buried dead
Neandertals which lived from 230,000 years ago until 30,000 years ago. • What makes these animals so interesting is that they are our genetic ancestors and our evolutionary cousins. • These species represent a very small part of the unbroken evolutionary tree from those first living organisms that appeared 3.5 billion years ago to every living thing on planet Earth today, including us!
Homo Sapiens Sapiens It is believed that modern humans like you and I first originated on the Earth around 50,000 years ago in Africa.
As Homo sapiens sapiens migrated outward from Africa, it is believed that they wiped out Neanderthals, either by absorbing them through intermarriage, or by destroying them through war and competition.
Homosapiens • 75,000 -10,000 yrs ago • Cave art development • Hominids evolved and developed for millions of years prior to the arrival of Homo sapiens on the Earth. • This evolution was slow. • The development of a new skill, or tool often took thousands of years. • With the arrival of Homo sapiens, this all changed. The speed of advancements increased dramatically. • Instead of thousands of years, great progress was made in hundreds or even dozens of years.
Around 8,000 years ago a new way of providing food emerged. This revolutionary advancement was that of farming. • Instead of hunting and gathering food from the environments where they lived, humans learned to simply grow their own food.
