Three hypothetical examples may clarify this: 1) Suppose a group of foragers (hunter-gatherers) is living at limits of food supply, such that any increase in the food energy they can harvest will lead to increased survival and/or reproductive success (number of offspring raised to maturity) If they can develop some new foraging technique or tool (e.g., toggle-head harpoon, way to leach tannic acid out of acorns) that will allow an increase in total energy harvested in the same amount of foraging time, this will result in increased reproductive success, and the innovation is likely to spread through choice (learning bias) or natural selection of memes (if children adopt parents' techniques) This is example of energy-limited population, where increase in efficiency of energy capture is adaptive because it increases the total energy available for consumption What about cases where energy is not limiting? 2)
