I think what its trying to say is race as a defined biological categorisation doesn't really exist, at least not to the extent its been described in past. The biological variance between humans is more of spectrum than categories.
race as a cultural / social concept does exist though, and that biology certainly correlates to an extent due to geography and how human society has traditionally functioned.
I.e, the cornish are a race, falling under celtic, which originate from Iberia, but is there a modern biological difference to their surrounding English people? Are they more biologically similar to the modern people inhabiting the Iberian peninsula or those in Kent? And even then, are they really all thatthat biologically different from the modern spanish anyways?

Proof? What do you think the people were asked in the survey? Normal people use race in the normal way. I think white people exist. I think black people exist. Everyone knows this - I don't need any academic to prove me wrong.
And I don't think it makes me racist when some one asks me "are there different human races" and I answer "yes".
Ah, but it gets messier than that. What's a Celt, anyway? It was traditionally believed that Celts were in some sense a single ethnic group, but the genetics don't _really_ support that, in particular for British and Irish Celts.
