《生物評論》涵蓋了整個生物科學領域，每期都有幾篇評論文章。雖然學術和廣泛的參考書目，文章是針對非專業生物學家以及該領域的研究人員。作者在寫作中被特別指示要意識到這一事實，由此產生的評論作為對特定領域的廣泛介紹，定義了技術的狀態，并提請注意知識的空白。文章長達兩萬字，每一篇都包含一個摘要，一個完整的介紹和結論陳述。

Biological Reviews covers the entire range of the biological sciences, presenting several review articles per issue. Although scholarly and with extensive bibliographies, the articles are aimed at non-specialist biologists as well as researchers in the field. Authors are specifically instructed to be aware of this fact in their writing, and the resulting reviews serve as extensive introductions to particular fields, defining the state of the art, and drawing attention to gaps in knowledge. Articles are up to 20,000 words long and each contains an abstract, a thorough introduction and statement of conclusions.
