This is a gravely misleading statement, insofar as even Old English did not exist at the time of the migration from northwest India. It would be more-correct to say that Indo-European emanated from that region.
Regards,
Most experts on Indo-European origins seem to think that the area just north of the Black Sea is where the ancestral population lived. I don’t think anyone thinks the language family originated in India other than some scholars in India. Nowadays the majority of the people in the subcontinent speak one of the Indo-European languages but they were introduced by “Aryan” invaders.
That sounds a little dramatic.
If you take the “Indo” out of “Indo-European,” how do you get to English?
Not through German, which would not exist either.
Anyway, I also enjoy rattling the cages of the Political Left by claiming that I am African-American, since 95% of my DNA emigrated from Africa about 70,000 years ago.
