Quote by Ronald J. Planer

“Humans became able to move much more freely through the landscape because their support networks were more stable over time. These supportive relations between groups made it possible for sapiens to colonize forbidding environments with very limited foods supplies, supporting only very small residential groups. A band of a family or two would not be stable over the long term, without support from a wider network. While small groups can penetrate harsher environments, they need social risk management. They need to be able to reconnect at times of need.”
