Dr Frank Ellis, a Russian tutor, said data stretching back 100 years pointed to a “persistent deviation” in the average IQ of black and white people.
The Students’ Union claim Dr Ellis has breeched requirements for staff to promote equality and want him sacked.
More than 200 students gathered at the city campus to make their views known.
Dr Ellis has expressed support for the Bell Curve theory, examined in a book by Richard Hernnstein and Charles Murray, which concludes that ethnicity can play a part in IQ levels.
