Answer 1

Many natural toxins taste bitter. Obviously making faces alone isn’t going to help you survive. But a negative response is going to stop you from eating more. And a very visible and immediate response cues the people around you that something’s wrong with the food. In our early days when we did a lot of foraging, the face reflex was probably an evolutionarily useful trait.
