How many races are there in the world ?

Most anthropologists recognize that there are three major race classifications in the world. In old days they were called Zapatize, Semetic, Hemetic, but nowadays they are termed as Mongoloid, Caucasian and Negroid. The Mongoloids were of yellow feature, the Caucasian were of white feature, and the Negroids were of black feature. The surrounding places of Shivalig Mountains were the original places of the Mongoloids.
Those original places lie within the periphery of modern China,
Nepal and India. The Aryans (who are also called Brahamins)
had spread out from Caucacious mountains. The Caucacious
Mountains lie between Caspian see and Black see, and they are in Russia these days. When the Haiti rulers invaded them before 19th century BC, a huge crowd of them fled from their original place and settled down in Iran for over four hundred years. Afterwards a branch of their race crossed Sindhu valley,
plundering and terrorising others until they reached India. That
was the history of 15th century BC. Thus, when they reached
India in around three thousand and five hundred years ago, they were known as plunderers and terrorists. 
They entered in present Nepal as refugees from the different parts of India. Especially from chitaur, Rajastan, Kumaun, Garwal hill, Kasi and Benaras. Among the Hindu aryan Shah family first stepped in 1495 AD. From the western part of present Nepal and the Ranas in 1559 AD. No sooner Hindu (Indo-aryan) entered in this holy land of Mongols as refugees then started a vicions net work of conspiracy against we the non Hindu indigenous(mulbasi) Mongol peoples. After 64 years they succeeded in their vicious conspiracy and be headed the Ghalay King of Gorkha in 1559 AD. by Drabya Shah then down fall of indigenous (mulbasi) peoples started.
