Final answer:
The answer is true; unconditioned responses such as fight or flight behavior have survival value because they enhance an individual's ability to cope with threats, leading to a higher likelihood of survival and reproduction.
Step-by-step explanation:
Unconditioned responses do indeed have survival value for an individual, so the answer to the question is true. For example, the fight or flight behavior is an unconditioned response that has been naturally selected because it helps individuals to survive in the face of threats.
As a result of natural selection, such traits that enhance an organism's ability to survive and reproduce become more common in a population over generations. This support of survival and reproduction allows individuals most adapted to their environment to pass their traits to the next generation.
Several mechanisms of evolution, including natural selection, could lead to the incorporation of survival traits into the human lineage. The fight or flight behavior not only increased immediate survival chances during threatening situations but was also likely inherited by offspring because individuals with such traits were more likely to survive and reproduce.
In conclusion, natural selection tends to favor traits that enhance survival and reproduction, thus unconditioned responses that help an individual to cope with its environment — like the fight or flight response — have significant survival value.
