Question

Which scenario is the most likely to result in natural selection that leads to adaptive evolution in a population of humans?

a. Mortality due to heart disease increases to 80% in middle-aged Americans.
b. Individuals colonize another planet and become isolated from earth.
c. A new influenza strain becomes an epidemic and kills all individuals over age 50.
d. Individuals in Australia only reproduce by random mating.
e. A tsunami kills hundreds of thousands of people in Southeast Asia.

Answer 1

Answer:

b. Individuals colonize another planet and become isolated from earth.

Explanation:

Natural selection is a theory by Charles Darwin which states that organisms best adapted to an environment are more likely to survive and pass that adaptation to their offspring. When individuals colonize a new planet and are isolated from Earth, those that best adapt to the new planet will likely survive and pass the adaptation to their offspring according to natural selection theory.

Answer 2

Natural Selection is an evolutionary process in which organisms better suited to the environment will tend to survive and reproduce. Natural selection can be affected by climate, mutation, and migration.

The correct answer is:

Option B. Individuals colonize another planet and become isolated from earth.

The theory of natural selection was given by Charles Darwin, which states that organisms better suited to the surrounding will more likely have a high survival rate.

The individuals when isolated from the Earth and colonize a new planet and will adapt to their surroundings. The adaptation will be transmitted to their offspring and will tend to survive and reproduce.

Therefore, the correct option is B.
