By examining the civilization, archeological data during pre historic era some facts have been revealed.
When exploring the history of Sri Lanka, it has been called "Sinhala Dvipa", "seehala Dvipa", "Heladiva",
and "Lankapura". There are lots of controversies with regards to the beginning of the human civilization
in the island.
Archeologists have undertaken many excavations in various parts of the island as to find the more solid
evidences with regards to the ancient man in Sri Lanka. After the pre-historic excavations done in Yala,
Panama, Bundala, Ambalantota, Bandarawela, Velimada, Suriyaknda and other sites in Sri Lanka, well
known archeologist Dr siran deraniyagala was able to reveal a pre-historic civilization dates back to
125000-26000 years, by excavating a coastal area in bundala. Dr deraniyagala revealed that there was
evidences to say there had been civilization of 25000 years old and those places belong to Stone age. Dr
deraniyagala adopted a archeological system called `Typology' to study pre-historic stone tools based on
data of exploration.
In 1978-1986 were excavated pre-historic caves. As result archeologists were able o recover the oldest
skeletons of the human being who lived in modern south Asia. It was calculated that those remains were
about 5000-37000 old. K.A.R Kenedy of Thronal University and Dr.D.Horkey of Arizona University did
technological research on the same matter. According to evidences found that there had been an ethnic
affinity of to Vedda clan from 30000 years ago. Also, for the first time it was reveal that there was a
resemblance between Sunhalese people and inhabitants during "Mohendajaro Harappa" civilization
where genetics were concerned.
Excavations were carried out in 1984 again on the basis of excavations done in 1969 in citadel of
Anurdhapura. The aim of this exploration was to observe the change from pre-historic era to historic
epoch. In the excavations Archeologists were able to unearth some ruins showing a city 30 feet beneath
Anuradhapura city that can be calculated to a civilization of 900-800 B.C.
That civilization dates back to 300-400 years before the starting of the written history of modern Sri
Lanka. It proved that there had been iron technology, rearing of Horses, paddy cultivation and advanced
pottery industry in the island.
The remnants of clay pots showed that they were belonged to 6 and 5 B.C. accordingly, history of Sri
Lanka starts not from the era of King Devanampiyatissa as some archeologists say, but that of about 250
years ago. It was too revealed that no such ancient history is found in any other region among countries
belong to Southern Asia.
Dr F.R Ollchin of Cambridge University says according to his research, Anuradhapura can be considered
the as the fifth town found in Indian region during the first era of history. Dr Ollchin mentions that such
an ancient town is not found even in Southern direction of city "Uppeni" in North India.
