The impacts and consequences of a hunter–gatherer foraging shift to regular use of coastal resources. See [72] for discussion.

	consequences
diet
constant year-long access to protein, fatty acids, omega-3	reduced child mortality
	overall improved health
	population growth
mobility
residential mobility reduced, more sedentary	stored resources, material culture, mates, and children concentrated in a ‘village’
	more permanent dwellings and formation of ‘villages’
	defence of territory
technology
sometimes increased investment in complex technologies	increased craft specialization
	more intensive storage
	permanent dwellings
sociality
larger group (band/local group) sizes	increased population density
	easier to defend resources and land around them
	easier to assemble large war parties
sometimes a reduction in egalitarian social ethos	hierarchical or ranked societies
elevated levels of intergroup conflict	high injury and mortality rates
	group extinction
	general societal discord
	slavery
long range social networks	information flow and trade
	long range gifting and trade
	reciprocal exogamy cycles widely across geography
