Problem:

The theory of natural selection has it that individuals with better genes tend to survive and reproduce, passing their genes to their offspring. This gradual process results in a population more adapted at survival. However, due to the advancement in medical science, humans with poorer genes tend to survive and reproduce just as well.

For example, in the past, many people, excluding those with natural immunity due to some genetic mutations, would have succumbed to illnesses such as malaria and typhoid. But with better hygiene and medical treatment, these patients tend to survive.

Now, imagine a future where all illnesses including cancer can be treated.

Required:

Question 1: How would it impact the survival of the human race?

Question 2: Would we become more and more vulnerable such that our survival hinges heavily on medical technology, analogous to howan astronaut's survival is dependent on his spacesuit?

Explain the impact of survival of human.
