BTW, pants were not invented until the horse was domesticated and horseback riding became common.

Mmmm not sure about that. I suppose it depends on what you call "Pants".

There were any number of non-riding societies in North America where they wore leggings.

Having your legs covered while going through brush is a major advantage.

Tocharians were an off-shoot of Aryans/Indo-Europeans. They probably came from the group that spread south-east and while the larger group went south to India and then west along the Persian gulf to become Gutians and then Hittites, the Tocharians went to the Tarim basin and then settled down and were eventually absorbed by various Turkic peoples. Some went south in about 200 BC to become the Kushans.

Their descendants would be

Rajputs

and those that stayed behind and were absorbed by the TurkiC peoples became Uyghur
