Question

How did receptors in the nose and on the tongue help our ancient ancestors survive?

Answer 1

Answer:

Helped them find food that would provide energy and nutrients.

Explanation:

Our ancestors had to find their food from the environment, and their perception of taste was important for survival and thriving. The sense of smell plays a decisive role in human societies, as it is linked to our taste for food, as well as our identification of pleasant and unpleasant substances.We have around 4 million smell cells in our noses, divided into about 400 different types. There is a large genetic variability within and between populations for our ability to detect odours. Each smell cell carries just one type of receptor for us to understand.

While many factors affected there choice of food and how we perceive its taste. When food meets our taste senses, raised bumps on our tongue called the papillae react.  the ability to assess the calorie intake and the nutrient value of the food, helped them detect dangerous or poisonous foods (which would tend to be bitter or sour). It also helped distinguish foods that appeared in new environments.
