Final answer:
Around 7000 BC, the human population was approximately 5 million, coinciding with the early stages of agriculture and the growth of settled communities.
Step-by-step explanation:
Based on historical data regarding human population growth, it is estimated that when farming was first introduced, the total human population was approximately 5 million. This period is representative of a critical change in human society, marking the transition from hunter-gatherer lifestyles to settled agricultural communities. Over time, these early agricultural practices led to the support of larger populations and spurred the growth of early civilizations. The question specifically asks about the population around 7000 BC, which is anchored before the time of rapid urbanization. Hence, based on the provided information that human population was around 5 to 10 million when farming was introduced, it is reasonable to infer that during 7000 BC, the population would be on the lower end of this range.
Given that the timeline shows a growth from approximately 5 million people at the introduction of farming to about 600 million by 1700 AD, it suggests a gradual increase. Therefore, considering that 7000 BC is closer in time to the introduction of farming, the population would likely have been closer to 5 million rather than significantly higher or lower.
