慈鲷科鱼类是一种研究 许多生物现象。 系统分类学家遗传学家动物行为学家， 比较和功能形态学家研究了这个科 可能比其他硬骨鱼类都多 的非凡 东非裂谷湖慈鲷的适应性辐射 它们是形态学、物种形成、 性选择。 这个家族的成员也生活在 在非洲、中美洲和南美洲、马达加斯加和印度。 的 本研究的主要目的是确定系统的 慈鲷科鱼类主要谱系之间的关系。 目前关于该科的系统发育假说及其 姐妹群关系完全基于形态学 字符，但形态趋同的证据表明， 重要的是要有独立的证据来证明生育能力。 DNA技术的最新进展使我们有可能 解决这里提出的范围的系统发育问题， 分子特征 线粒体基因将被测序， 用于构建系统发育的系统发育信息 慈鲷科主要谱系之间的关系。

The fish family Cichlidae, is a model system for the study of many biological phenomena. Systematists, geneticists, ethologists, comparative and functional morphologists have studied this family probably more than any other teleostean group. The extraordinary adaptive radiation of cichlids in the East African Rift Lakes make them an important subject for the study of morphology, speciation, and sexual selection. Members of this family of fishes also live in Africa, Central and South America, Madagascar and India. The general aim of this study is to determine the systematic relationships among the major lineages of cichlid fishes. Current phylogenetic hypotheses about this family and its sistergroup relationships are exclusively based on morphological characters, but evidence of morphological convergence suggests that it will be important to have independent evidence of phylogeny. Recent advances in DNA technology have made it possible to address phylogenetic questions of the scope proposed here with molecular characters. Mitochondrial genes will be sequenced and the phylogenetic information used to construct phylogenetic relationships among the major lineages of cichlids.
