                      ANCIENT HISTORY

HUMAN DEVELOPEMENT SEQUENCE 

1. Political expansion


 2. Administration


 3. Economy


 4. Society


 5. Religion

* The ancient history has been divided into two parts. First on the basis of equipment used by humans and second on the basis of speech scripts. On the basis of the first division, history is divided into three parts.

* History Division 1

 1. Full Stone Age


 2. Middle Stone Age


 3. Neolithic period

* History Division 2

- - The second division of history has been done on the basis of the interpretation of scripts and literature.


1. Prehistoric period - There is a lack of written evidence for the information of this period. Pre-3000 BC


2. Historical period - written evidence is available but it has not been eloquent. The human of this period displayed their activities in such a way that the later literate human understood it with ease. Period up to about 600 BC.

3. Historical period - In this period, written evidence is available to understand the history and its eloquence has also been done. The period after 600 BC.

 * Earth's evolution

 - Earth is believed to be 400 million years old.  The development of its layer reveals four stages.  The fourth of which is called Chaturthaki.


 1. EON- The largest time segment.


 2. ERA- (Mahakalpa) - Many million years ago


 3. PERIOD- (Kalpa) - 10-100 million years ago


 4. EPOCH- (era) - 10 million years ago


 5. AGE- (Period) - A few million years ago


 * EON- (Age)


 - EON is of four types.


 1. Headion


 2. Akiyan


 3. Protozoic


 4. Fanozoic


 * The first three together are called Cambrian pre-Mahayon.


 * The first fossils discovered in the Cambrian period are believed to be 500 million years old.


 * The first vertebrate (spinal cord) animal was born 40 million years.


 * Dinosaurs originated 200 million years ago.  And lived 10 million years ago.


 * Mammal creatures on Earth were born 7 million years.


 * Human origin on Earth is believed to be 10 million years ago.


 * Chaturthi has two parts.


 1. Pleistocene


 (20 lakh to 10 thousand years ago)


 - The name Pleistocene was given by Sir Chales Lyall in 1839 AD.


 - Man was born in the Plytosin era.


 - At this time real cow, real elephant and real horse came into existence.  This incident took place 26 million years ago in Africa.  These animal models are collectively called the Villa French Animal Group.


 2. Holocene (10 thousand years to present)

 * Human evolution - Ramapithecus



 * About 3.5-2 million years ago, a kapi group about 3-4 feet high, came out of the thickly forested forests and reached the boundary of the forest due to climatic changes or increase in its number.  Later, these groups were adapted to field life.  This adaptation produced two important effects.  First, they started using some stone tools and secondly they started running in a semi-advanced state.  As a result, he got free from the task of walking.  This was further known as the Rampithecus group.


 * Australopithecus

Australopithecus



 Later, Ramapithekas also got divided into two parts.  Its branch which remained in the forest and was more adapted to live on earth was classified as Maha Kapi.  Whereas, the other group that preferred to live in open grasslands was later known as Ostralopithecus group.  This group became the original ancestor of humans.  Most of its presence was seen in Africa itself.  It used to walk straight but the back remained bent so that the balance of the body would remain at the waist.


 * Penthecanthops

penthecanthops


 Further, the bones of such human have been found from the tropical grassland of Africa to the temperate grassland of China.  The one who could walk upright has been labeled as Penthecanthops.  The skull of this human was more spherical than the previous group.  The height was 5 feet.  Hands and feet were convoluted.  Due to ground stability, its vision was also high.


 -


 * Neanderthal

neanderthal


 The next development of humans took place as the Neanderthal Group.  The name has been given on the basis of human remains derived from the Neandar Valley of Germany.  It used to bend with its neck straight.  It represented the human Middle Stone Age.  Its capability was similar to that of modern humans.  This group had a tendency to respect its mortals in humans.  The center of speech of this human brain was developed.  And had the ability to speak letter bound language.  After this group, about 40 thousand years ago, modern human homosepians emerged.

 * Homosepians

homosepians


 Today about 40 thousand years ago, modern human homocepiones emerged.  It had two important physical symptoms that had not been seen before.  The first is the development of a raised chin and the second is the circularity of the skull's front.  Many of its progenitors were Cromagnan, Grimaldi, Chlsld. These tribes later formed the basis of large human species such as Caucasus, Megoloid and Nigroyoid.
