脊椎动物的视觉系统表现出惊人的多样性，反映了它们对各种颜色环境的适应性反应。感光分子，视觉色素。可以在体外合成，并且可以测定它们的吸收光谱。比较各种视色素的氨基酸序列和吸收光谱，我们可以确定改变视色素吸收光谱的氨基酸变化。然后可以使用体外测定来检验这些假设。这种方法已经成为一个强大的工具，不仅阐明了色觉的分子基础，但在分子水平上的适应性进化的过程。(C)2002 Elsevier Science B.V.保留所有权利。
Visual systems of vertebrates exhibit a striking level of diversity, reflecting their adaptive responses to various color environments. The photosensitive molecules, visual pigments. can be synthesized in vitro and their absorption spectra can be determined. Comparing the amino acid sequences and absorption spectra of various visual pigments, we can identify amino acid changes that have modified the absorption spectra of visual pigments. These hypotheses can then be tested using the in vitro assay. This approach has been a powerful tool in elucidating not only the molecular bases of color vision, but the processes of adaptive evolution at the molecular level. (C) 2002 Elsevier Science B.V.
