I am currently reading the book Sapiens: A Brief History of Humankind by Yuval Noah Harari. It's a great read on humanity and evolution. One interesting detail is that there were several different species of humans that lived on the earth. Eventually all other species disappeared. Homo sapiens won out in the end, but why?
We don't have a written history or YouTube videos to document what happened, so there is much speculation based on what little archaeological data that exists. Were there traits that Neanderthals lacked that Homo sapiens have that gave us an evolutionary edge?
We may never know the answer to these questions from our deep past. However, perhaps Homo sapiens were a little better at non-verbal cues when working together that gave us an edge. Dr. Albert Mehrabian did a well-known study in the 60s that became known as the "7%-38%-55% Rule". The rule postulates that when conveying a message, words account for 7%, the tone of the voice for 38%, and non-verbal body language for 55%. Maybe Homo sapiens got an important message across with more efficiency that helped us work better together and led us to become the dominant species over time.
At Dialogic, our PowerMedia XMS product helps drive our PowerVille Video Conferencing solution, and is also used to build compelling solutions by our developer partners. I personally am in a regular staff meeting that uses a PowerVille Video Conferencing bridge and it is a richer, more collaborative experience than the normal audio-only bridge. One might say it makes our meeting 55% better!
