Sindhu Civilization Was Indeed Harmed Badly By Climate
Yama Dixit, David A. Hodell and Cameron A. Petrie
Abrupt weakening of the summer monsoon in northwest India ∼4100 yr ago
The paper Suggests:
The 4.2 ka aridification event is regarded as one of the most severe climatic changes in the Holocene, and affected several Early Bronze Age populations from the Aegean to the ancient Near East (Cullen et al., 2000; Weiss and Brad- ley, 2001). This study demonstrates that the cli- mate changes at that time extended to the plains of northwestern India. The Kotla Dahar record alone cannot fully explain the role of climate change in the cultural evolution of the Indus civilization. The Indus settlements spanned a diverse range of environmental and ecological zones (Wright, 2010; Petrie, 2013); therefore, correlation of evidence for climate change and the decline of Indus urbanism requires a comprehensive assessment of the relationship between settlement and climate across a sub- stantial area (Weiss and Bradley, 2001; Petrie, 2013). The impact of the abrupt climate event in India and West Asia records, and that observed at Kotla Dahar, on settled life in the Indus region warrants further investigation.The Conclusion:
Climate change has been suggested as a possible cause for the decline of urban centers of the Indus Civilization ∼4000 yr ago, but extant paleoclimatic evidence has been derived from locations well outside the distribution of Indus settlements. Here we report an oxygen isotope record of gastropod aragonite (δ18Oa) from Holocene sediments of paleolake Kotla Dahar (Haryana, India), which is adjacent to Indus settlements and documents Indian summer monsoon (ISM) variability for the past 6.5 k.y. A 4‰ increase in δ18Oa occurred at ca. 4.1 ka marking a peak in the evaporation/precipitation ratio in the lake catchment related to weakening of the ISM. Although dating uncertainty exists in both climate and archaeological records, the drought event 4.1 ka on the northwestern Indian plains is within the radiocarbon age range for the beginning of Indus de-urbanization, suggesting that climate may have played a role in the Indus cultural transformation.

Indus Script Based on Sanskrit Language
Feb 21, 2014 by Jeyakumar Ramasami
Inscriptions on Indus seals give details about animals sacrificed and nature of ceremony. Some ceremonies were performed for obtaining remission of sins and others were for pleasing the souls of dead ancestors (Pithru Karma ceremony).
Indus script had remained un-deciphered for a long time. There are some valid reasons for that. The Indus valley civilization flourished quite a long time back, approximately 4,000 years back.
The time gap is really big and the modern day man is not able to visualize the context in which these seals were prepared and what is written over those seals.
The earliest Indus archaeologists made the fundamental mistake of identifying these excavation sites as a “Megapolises,” whereas in reality they were “Necropolises.” This fundamental mistake had made it difficult to identify and recognize the role of seals and its inscriptions.
There are many decipherments of Indus seal inscriptions, some are based on Dravidian language and others are based on Aryan language. But, none of the decipherer is able to prove anything convincingly because there is no reference point.
Ancient Egyptian hieroglyphics code was broken using the tri-lingual inscription made on “Rosetta stone.” Whereas no such bilingual record are available in the case of Indus scripts so far. That doesn’t mean this Indus script had to remain un-deciphered. There are some other methods available to overcome this deficiency.
It is likely that Indus seals were “tokens of evidence” prepared to show the god of death that blood sacrifice had been made so that the dead man’s soul can pass through the trial and accepted in heaven, which is similar to the religious ideas of ancient Egypt.
The first symbol identified by me was “fish” symbol (Matsya), which stood for “Ma” sound. Interpretation of this symbol is quite easy and simple.
Whereas identifying the second commonly used symbol was not that much easy task and the second symbol identified was , which stood for phonetic sound of “Ka/Ga.”
Various names of gods have also been inscribed in Indus seals, however “God Indra” was quite popular and his name appears in many seals.
Next in importance is “goddess Hera,” which is quite unknown in India, however this name was quite popular among ancient Greeks, which shows the link between IVC and ancient Greek civilization.
Another major problem in reading the Indus inscriptions is that the direction from which the inscription should be read. While reading the Indus inscription, the reading should start from the side, which the animal is facing, which was the principle used by the Egyptian hieroglyphic writers.
The language of the Indus script had remained as a puzzle for long time and the conclusion now arrived at is that Indus scripts are written in “logo-syllabic” way and all the Indus inscriptions are based on Sanskrit language.
The methodology used in this decipherment effort is quite simple. I used an analysis table consisting of four steps.
Firstly, the figures (objects) shown in the inscriptions on the seal were identified.
Secondly, the Sanskrit names of the identified objects were obtained throughonline Sanskrit dictionary “Spokensanskrit,” which was quite useful in searching for the Sanskrit words.
Thirdly, the first letter of the object alone is taken out to form the word and the phonetic sound is obtained by using Logogram – syllabic method of reading.
Fourthly, if the word obtained is not giving correct sound and meaning, then the phonetic sound should be tweaked to get a meaningful word.
Copper tablets found in Mohenjo Daro have been analyzed by Prof Asko Parpola from the University of Helsinki and details are as given in his book Deciphering the Indus script (pp. 111-112). These copper tablets have all the qualities of bi-lingual inscription.
In the absence of Rosetta stone in Indus civilization, these copper tablets should be used as a reference point for Indus script decipherment.
Now, I would like to present first a simple word deciphered, so that it will be easy to understand. Rat is the “vahana” of God Ganesha, and the below given picture shows the rat in Indus copper tablets.
This inscription on this below given copper tablet should be read from “right to left:”
The final conclusion is that the name of rat in Indus language was “Musika.”
Nearly 115 symbols with their phonetic sound have been identified and the details are as given in the Indus Dictionary – Syllables.
Nearly 42 words have been identified so far, and many are merely repetition of these commonly found words, read in the Indus Dictionary – Words.

From Dna sequencing down to Parasite Eggs : The downfall of Farmana aDNA
There was the indication that they will Fail to yield the aDNA which i declared as the most important at least for the Indo-European study and for the history of the Aryans but now it appears that they may still come up with something useful, it is not the end...
Scientists to study parasite eggs in Harappan graves
Neha Madaan,TNN | Jan 12, 2014, 12.37 AM IST
PUNE: Archaeologists and scientists may soon find out who exactly the Harappans were, and trace their origin and biological connection with people outside the Harappan region.
After failed attempts to undertake DNA andgenome sequencing of Harappan skeletons in Farmana, Harayana, as the wet, acidic earth of the region had destroyed all DNA in the remains of the dead, archaeologists from the Deccan College Postgraduate and Research Institute have now moved towards the Harappan burials on a private land near Rakhigarhi, which is estimated to be the largest Harappan civilization site located in Hisar district, Haryana and listed among the 10 most endangered heritage sites in Asia.
Partnering with the Archaeological Survey of India (ASI) and paleoparasitologists from the Seoul National University College of Medicine, Korea, scientists from the Deccan College Post-graduate and Research Institute will now try to capture and study the parasite eggsthat once existed in the stomachs of those buried during the Harappan era, and ultimately isolate the DNA of their host, deposited within these eggs.
These parasites eggs are known to survive for thousands of years and contain the DNA of the host. Scientists said that they would therefore recover the DNA of the dead from these eggs, which in all possibility still remains in the soil where the dead were buried. The DNA will help scientists find out who the Harappans were and trace their origin and biological connection with people outside the Harappan region.
This exercise is part of the fresh excavations that will start in Rakhigarhi from January 12 under the direction of Vasant Shinde, senior archaeologist and vice chancellor/director at the Deccan College Postgraduate and Research Institute. Some of these archaeologists have already reached ground zero and will begin excavation at 'mound number 4'-- the biggest and the tallest of the seven mounds here.
Shinde told TOI that the authorities of the college will approach the landowners of the private land where the burials lay. "Some headway has already been made in terms of the land owners' permission to undertake excavation at this burial site. We had earlier tried to recover and identify the DNA from the remains of the Harappan dead in Farmana, which is around 30-40 km away from Rakhigarhi. But the exercise yielded no result as the ground there is wet and acidic, which is not conducive to the survival of DNA," said Shinde.
Shinde said that archaeologists have already done enough scientific work on the burial customs of the Harappans. "However, what still stumps archaeologists are questions like who exactly were the Harappans and what were their relations with the contemporary people outside of the Harappan region. The only way these questions can be answered is by recovering the DNA of the deceased Harappan," he said.
Shinde said that professor Dong Hoon Shin from Seoul National University College of Medicine has developed a new technique which involves the study of parasites found in the human stomach.
"Every human being has parasites and their eggs in the intestine as a result of ingesting polluted food or water. But even after the death of a person, these parasites survive. Scientists will thus collect soil samples around the lower abdominal skeleton of the deceased to find human parasite eggs," said Shinde, adding that a similar experiment was undertaken in Korea and scientists succeeded in isolating human DNA from such parasite eggs.
Scientists have said that once these tiny eggs deposit in the soil, they get hardened and survive for years.
"The DNA found in the eggs differs from person to person. Every person has different DNA, which comes out clearly after studying these eggs. Hence, scientists can also identify different ancient populations as well as their blood groups once they have recovered these eggs and studied them. This is the only method that has been effective enough to identify DNA of those having died thousands of years ago," he said.
The team of Korean scientists will reach Rakhigarhi on January 25 to begin experiments, which in fact is the result of an official memorandum of understanding (MoU) between Deccan College and Seoul National University College of Medicine, Korea.
"Sometimes these parasite eggs are found in the drainage areas of habitations. Scientists will therefore get soil samples from places such as the Harappan lavatories, drainage and bathing areas during excavations," Shinde said.
