Dear Tamara, welcome again.
A question, since you study (bio)psychology. OK, it is more a sociological type of question but nevertheless ...
What differentiates us humans from other living creatures on this beautiful planet? Thank you for your answer!
Thank you and I'm really sorry for late answer but I've been busy studing. That's a very hard question to answer. We're pretty much the same, specially with chimps. In one book it was mestioned one theory that only humans can travel in time. We can talk about our past, relatives, achivements and things someone has done. We can also talk about our plans for the future. In animals they haven't found this "skills", for now. That's unfortunatly all that I know about that. :) What do you think?
