Final answer:
The population pressure model was developed during the Neolithic period as a means to adapt to the demands of the rise of agriculture and increased population density.
Step-by-step explanation:
The population pressure model suggests that it was developed by humans during the Neolithic period as a means to adapt to the demands created by the rise of agriculture and the increase in population density. The Neolithic Revolution, which began around 12,000 years ago, marked a significant shift in human societies from nomadic hunting and gathering to settled farming communities. With the adoption of agriculture and the domestication of animals, humans were able to support larger populations and ensure a more stable food supply. However, this also led to increased competition for resources and changes in social structure.
