yes start over, and may i recommend, use 1 villager for food, 2 for tech, and should either have 2 youths, or 1 adult + 1 youth, or you select 2 additional adults(i recommend 2 kids).
if going with 4 adults, put the 4th on building.
any youths/kids, just use to pick up mushrooms/collection pieces).
but always try to have more villagers on research at a 2.1.1 ratio or more(2.1.1/2.1.0 starting, 3.1.1/3.2.0 when population picks up).
