teratogens

Many plants produce toxins as a defense against predators and our taste buds have evolved to sense this
Not a big problem as an adult; HUGE problem as an embryo though
Margie Profet’s Hypothesis
pregnancy sickness is an adaptation to prevent the ingestion of teratogens.
Food aversions, nausea, ans vomiting
