They were originally the same species as Aryans in Europe, so they were called Aryans in India. Around 2500 BC, Aryans once took advantage of the trend of the world racial movement and moved in two directions. One was from Central Asia to Europe, becoming the ancestor of Europeans today, and the other was from Central Asia to the south, crossing the two plateaus of Hindu Kush and Karakorum, and staying in the Iranian plateau and India. They became the ancestors of Iranians and Indians. Aryans began to occupy Punjab in the upper reaches of the Indus River in northwest India, and then gradually developed eastward until the upper reaches of the Ganges River. They found that the land here was fertile and rich in resources, so the number of immigrants increased day by day, forming the Aryan race in India. Aryans were originally white, but their appearance was obviously European: tall, with a long head, a lot of beards and a thin nose. Today, many Indians belong to their descendants, or become their hybrids. Now, people with pure blood can be seen, such as Rajpuuf and Chater, mainly distributed in Punjab and Rajasthan. It is also said that Hindu monks may be pure Aryans. The ancient Indian book Vedas mentioned an Aryan who believed in Vulcan.
