It's full of mistakes. Too many. I'll begin.
First mistake. They're not "Races" of Pakistan, they're ethnic groups of Pakistan. Pakistan is mainly a single race, but many ethnic groups (call them sub-races if you want to).
This is taken from wiki so you can imagine how incorrect it would be.
Punjabi people - Wikipedia, the free encyclopedia
Eastern Punjabis I guess are an "Indian race", Pathans are not an Indian race. Western Punjabis are a Pakistani ethnic group. The origin of the Punjabis I would say is part Aryan and part Dravidian. The most Aryan people in Asia I would say are Pashtuns along the Afghan-Pak border. By the time the Eastern Indo-Pak border is reached the majority of people begin to look different.
Well this is all nonsense. Punjabis are basically Pashtun, but more dravidianized. The Dravidian epicentre is in central India, so it would be expected that they would be more dravidianzed than Pashtuns.
Well, Baloch are definitely not an "Iranian" people genetically. They might be classed as speaking an Iranic language, which doesn't mean much, and certainly isn't related to modern day Iran. It's a deceptive description to call the Balock an "Iranian" people..they have nothing in common with Persians who form the majority of modern day Iran.

Baloch people - Wikipedia, the free encyclopedia
Baloch have nothing to do with modern day Iran, linguistically or genetically. Kurds are another matter.
"The Dravidian culture blossomed over the centuries and gave rise to the Indus Valley Civilization of Ancient India" .. need I say anymore? It's obviously written by some Indian claiming the Indus Valley Civilization was a Tamil/Dravidian civilization.
Well this is all bs. It's from Mosaich.com, and that site really does post rubbish. Pathans have nothing to do with any lost tribe of Israel. This has been genetically proved. Pathans have everything to do with Central Asia, and if there's any group in Asia that could claim to be Aryan, the Pathans would have the biggest creditable reasons to claim it. Much genetic evidence and physical evidence supports this.
