The Cognitive Trade off Hypothesis

Notes on The Cognitive Trade off Hypothesis, if communication was developed simply by "sharing" - doesn't it mean there are alternative forms of communication? Spoken language was developed because our ancestors came out of the forest and exposed themselves to more vulnerable conditions. They lost their short term memory skills to make room for more long term memories. Primates live in the "present" moment, they need short term memory skills to quickly assess a dangerous situation. There is no need for the past and future, although habit does form through repetition for the primates which ensures successful future reproduction. Homo Sapiens consciously remember their past and present to teach one another how to share, communicate and learn from experiences in the past to make for better survival in the future. Back to language, the spoken word is just as limited as the unspoken word. Prior to the development of language in our ancestors, there was still communication in the very beginning. Perhaps through symbols, drawings and other sorts of representation. Very interesting. Or through body language and systematic cues. Simple things, underlines or highlighting symbols, colors, nods, blinks with our eyes, codes, etc are just some of the forms of alternative communication we experience on a daily basis.

But what if there's more going on? More than physical or spoken communication. Our brains can't fathom other forms but I think many feel other kinds inside through emotions. Isn't that what intuition is? Or if you are in a terrible mood, you put off negative energy resulting in negative communication so then your spouse or loved one might pick up on this. There is so much humans don't understand yet, I often wonder... "What will be our next evolutionary genome?" I can't even begin to imagine.
