Question

Quizplus · Accepted Answer

Pregnancy sickness likely evolved as an adaptation to help avoid toxins that could harm the developing baby. Nausea and vomiting can be triggered by smells, tastes, and textures that would not normally make a person sick, which suggests that the body is detecting potential harmful substances and trying to get rid of them. Additionally, pregnant women are more sensitive to bitter tastes, which are often associated with toxins. All of these factors suggest that pregnancy sickness is a mechanism to protect the developing fetus from exposure to harmful substances.
