Question

which statement better explains the concept of evolutionary success? choose 1 answer: a individuals that inherit advantageous variations will outcompete others for resources and pass these variations to the next generation. b individuals that acquire advantageous traits over their lifetime will survive better and pass those traits on to their offspring. c individuals that develop advantageous physical traits will outcompete others for resources, and pass these traits to their offspring. d individuals in a reduced gene pool can withstand environmental changes and will survive more frequently than other individuals.

Explanation:

To determine the correct answer, we analyze each option based on evolutionary theory:

• Option A: Evolutionary success involves individuals with inherited advantageous variations (due to genetic differences) outcompeting others for resources and passing these variations to the next generation. This aligns with natural selection, where heritable traits are key.
• Option B: Acquiring traits over a lifetime (like Lamarckism) is incorrect, as acquired traits are not heritable in the context of modern evolutionary theory.
• Option C: Developing physical traits (implying acquired or non - heritable development) is wrong, as evolution relies on heritable genetic variations, not developed traits during an individual's life.
• Option D: A reduced gene pool typically leads to less genetic diversity, making a population less likely to withstand environmental changes, so this is incorrect.

Answer:

A. Individuals that inherit advantageous variations will outcompete others for resources and pass these variations to the next generation.
