How did early human societies view pregnant woman?

Early human societies often viewed pregnant women as vital to survival. In hunter-gatherer communities, the ability to bear and nurture children was essential for the continuation of the group, making pregnant women significant for societal survival. Their roles were often respected, and their physical well-being was pivotal to the health of both the mother and the future generation.

While views and treatment could vary significantly across different cultures and periods, the general consensus is that pregnant women were seen as important due to their reproductive capabilities, which were directly linked to the group's survival and continuity. The other options you mentioned—unimportant, pregnancy having no effect on female importance, or being seen as working servants—do not accurately capture the essential role of pregnant women in early human societies.

It is important, however, to note that cultural practices and beliefs about pregnancy could vary widely across different groups, and there may have been some societies with less favorable views of women in general.
