A recent study in India's Saurashtra peninsula suggests that early human migration may have followed inland routes rather than coastal ones, challenging the coastal migration theory.
Tools discovered in Saurashtra, dating back 56,000-48,000 years, support the idea that humans dispersed through inland areas
Saurashtra region
Saurashtra, also known as Kathiawar, is a peninsular region of Gujarat, located on the Arabian Sea coast.
Saurashtra peninsula is bound on the south and south-west by the Arabian Sea, on the north-west by the Gulf of Kutch and on the east by the Gulf of Khambhat.
The Saurashtra Basin is covered largely by volcanic rocks known as the Deccan Traps.
It spans an area of 240,000 square kilometers, including parts of western Gujarat and the north of Mumbai coastline.
The basin was formed by the separation of India from Madagascar around 100 million years ago.
This event led to the creation of lowlands in western India and highlands in the northern and northeastern regions.
The basin contains Mesozoic era sandstones, primarily originating from Neoproterozoic and Archean rocks.
The region is mentioned in the Junagadh Rock inscription dating 150 CE, attributed to Rudradaman I.
