The use of war canoes (red, Fig. 2E) is estimated to appear 90,000 to 60,000 YBP, and correlates with the appearance of ritual fights and protective weapons.
This transition correlates (p < 0.05) with other cultural traits analyzed here, such as the invention of protective weapons like shields and/or armors (Fig. 2D) and the use of dugout canoes as war canoes (Fig. 2E).
The technological developments achieved by the "Out of Africa Tribe," such as the war canoes and the protective weapons, could have given them a competitive advantage over other coexisting hominids such as the Neanderthals or the Denisovans, - and help them expand, specially along the coast and the big rivers of South Asia, Africa and Oceania.
However, around 80,000 y before present, a transition occurred, from this ancestral hunting tradition, toward the invention of protective weapons such as shields, the appearance of ritual fighting as a socially accepted behavior and the construction of war canoes for the fast transport of large numbers of warriors.
In other words, the timeline draw by the genetic tree and the stochastic character mapping using mtDNA phylogenies suggests the existence of a cultural transition from hunting societies to war faring societies, marked by the correlated appearance of ritual fighting, the invention of protective weapons and war canoes 90,000 to 70,000 years before present (Fig. 3).
Moreover, in the light of the recent Out of Africa Theory, it suggests that the "Out of Africa Tribe" was a tribe of warriors that had developed protective weapons such as shields and used big war canoes to travel the sea coast and big rivers in raiding expeditions.
