English to Polish Other Idioms / Maxims / Sayings

Prosiłbym o pomoc w tłumaczeniu tego zwrotu w poniższym kontekście.

"Language might well be programmed into the brain but, despite this, people still need
stimulus from others around them. From studies, we know that if / when/ whenever children are isolated from
human contact and have not learnt to construct sentences before they are ten, it is doubtful they will ever do so.
This research shows, if little else, that language is a social activity, not something
invented in isolation."
