文章开篇引用了 W. E. B. Du Bois 这位 American sociologist 在一个多世纪前的观点，他当时就 concerned 种族被误用为 biological explanation。这个 quotation 为全文奠定了 historical context，证明 race as social construct 的观点并非新近提出，而是有 long-standing academic foundation。通过引用 Du Bois 这样的 pioneering scholar，作者增强了论点的 credibility 和 authority，同时也暗示这个 scientific consensus 经过了时间的检验。

第二段直接给出了 mainstream scientific belief：race is a social construct without biological meaning。这个 clear-cut definition 是全文的 theoretical foundation，它 explicitly states 科学界对 race 的 current understanding。通过这个 definition，作者 establish 了讨论的 conceptual framework，让读者明确理解接下来所有 arguments 都基于这个 premise。

第四段 Yudell 指出了一个 paradox：一方面 race 被视为 useful tool 来 illuminate genetic diversity，另一方面它又是 poorly defined marker。这个 contrast 通过 on the one hand... on the other hand 的结构清晰呈现。这种 comparison 揭示了现代 genetics research 中的 internal contradiction，强化了需要 phase out racial categories 的论点。通过 juxtapose 两个 conflicting perspectives，作者展示了当前 conceptual framework 的 inherent problem。
信号词
however in contrast while whereas compared to unlike on the contrary conversely but
仿写： 当你需要 expose contradictions 或 highlight tensions 时，explicit comparison structure 非常有效。思考：你的主题存在哪些 inherent paradoxes？哪些 conflicting practices 或 beliefs 并存？模版：On the one hand, [概念/做法] is understood to be [作用A], but on the other hand, [同一概念/做法] is also understood to be [作用B/问题]。

第五段 Yudell 说如果基于 somebody's race 做 clinical predictions，you're going to be wrong a good chunk of the time。这个 direct quotation 强调了 racial assumptions 在 medical practice 中的 unreliability，为后续的 cystic fibrosis 例子提供了 expert assessment。
