Question

which of these statements best sums up evolution?
rapid development of vestigial structures in a species
change in a population through genetic variation over time
rapid change in species habits and features
change in a population through new species being made

Explanation:

To determine the best summary of evolution, we analyze each option:

• "rapid development of vestigial structures in a species": Evolution is not defined by rapid vestigial structure development; vestigial structures are a result, not the core of evolution.
• "change in a population through genetic variation over time": Evolution is the process of populations changing over generations due to genetic variations (like mutations, natural selection acting on variations), this matches the scientific definition.
• "rapid change in species’ habits and features": Evolution is typically a gradual process, not rapid, and focuses on genetic changes, not just habits/features.
• "change in a population through new species being made": Evolution is about change in existing populations (and can lead to speciation, but the core is population change over time via genetic variation, not "new species being made" as a primary definition).

Answer:

B. change in a population through genetic variation over time (assuming the options are labeled A, B, C, D with the first option as A, second as B, third as C, fourth as D)
