The team, which published their findings in the journal Nature Communications, places the beginnings of speech development to around 1.8 to 2.5 million years and is betting the hot topic at that time was tools.
Hunting implements were created by the hominid ancestors living in the African grasslands about 2 and a half million years ago, and teaching others how to fashion them may have been what pushed along the advancement of verbal communication.
That theory is the result of numerous trials that involved using 5 methods to demonstrate tool assembly.
The lessons were given to approximately 180 college students.
Some were non-verbal presentations, while others included either gestural indicators or actual words.
