I am aware of that fact. And after a search on pubmed and ISI web of knowledge I have not been able to find a paper stating that sign taught chimps have a conceptional understanding of science, the word science, or even have a symbol for science.There was a reason I mentioned chimps. Many have been taught sign language and can talk with humans. I'm surprised you don't know that.
I suspect your response was merely an attempt at a serious reply since it was without referenced sources.
I do suggest as a general literature some articles or books by behaviouralist Frans de waal. Chimps do have politics, morals, culture, and technology.

I do hope that in the future this subforum will be more serious.
And I think this entry concludes this tangent from the real thread topic. Please, let us return to the real topic of discussion and leave casual remarks on an unrelated topic for freethoughts or the cesspool.
