Read Explanation:

  • Sentence 2 opens by stating the big idea: life's diversity results from gradual change over vast time. This is a natural introduction to the paragraph.

  • Sentence 4 follows by explaining how the process begins: with inherited variation among individuals, where some have advantageous characteristics.

  • Sentence 3 continues by describing the next step: this leads to the gradual accumulation of favorable traits within a population.

  • Sentence 1 concludes by naming the process (natural selection) and emphasizing its importance: it's a cornerstone of evolution ensuring only the best-suited individuals survive to reproduce.

Flow: general statement (2) → how it begins (4) → what happens next (3) → significance/importance (1).
