To observe wild animals..without at the same time gaining the impression, somewhat prevalent today, that watching animals in the wild constitutes 'high' science. Who said that?

The full quotation is: 

Climbing in the country provided ample opportunities to observe baboons and other wild animals, without at the same time gaining the impression, somewhat prevalent today, that watching animals in the wild constitutes 'high' science.

From Lord Solly Zuckerman's biography, From Apes to Warlords, Hamish Hamilton, 1978, page 7, describing his schooldays in South Africa.

But who, in the 1970s, was Zuckerman having a go at? My guess is the then up-and-coming primatologists like Jane Goodall and Diane Fossey.
