In my opinion, the language is a very enigmatic skill of the humans, is like an attempt to show our subjectivities and our reflections. Mark Pagel says that in the origins, the humans like the Homo erectus has just the skill of social learning, that is learn through the visual theft, copy the things that others persons do. I think that we currently use the social learning and sometimes, is very useful, in addition, also using the language we can see a social learning, not so much linked with the visual theft, maybe, a “listen theft”.  In this line, Mark says that in a moment of our evolution, we had to choose between two options: live in small groups or in cooperative societies. Pagel tell that if we had choose to live in small groups, we would probably still living like the Neanderthals, because in small groups are fewer ideas, and for this, not language. On the other hand, living in cooperative societies means replace the visual theft for the language. In my opinion, that is problematic, because I don’t think that in small groups are less ideas than in a big group, actually, exist many small groups like hunter-gatherers who have complex ideas and very rich languages, for that, I disagree with the idea of one world one language, that would be very destructive, even more considering that the peoples would not like to change his ancient language. Anyway, I agree respect the power of the language, with that we can change our lives and change the world.
Considering the language and specifically the Chilean case, I think that the language is something mutable which operates in the practice, not in dictionaries or grammaticism laws, in this line, we can change that conscious or unconscious, and that is not bad.
