The karyotype of four Galagidae (Galago senegalensis, G. demidovii, G. alleni and Euoticus elegantulus) are studied and compared with the aid of various banding techniques. Many common chromosome segments were found, and it was possible to reconstruct a hypothetical ancestral karyotype for the family. It was also possible to show the relation between the chromosomes of Galagidae with those of two Lorisidae. The general scheme of chromosomal evolution of the Lorisiforms can be proposed, resulting from a common populational evolution followed by an accumulation of translocations, mostly of the Robertsonian type. Several pericentric inversions have also occurred in the trunk of the Lorisidae, emerging from this common population. Then, Galagidae have evolved, each species independently, by an accumulation of translocations, mostly Robertsonian, whereas Lorisidae have accumulated pericentric inversions prior diverging.
利用各种显带技术对四种婴猴科动物（塞内加尔婴猴、德米多夫婴猴、阿伦氏婴猴和优雅懒猴）的核型进行了研究和比较。发现了许多常见的染色体片段，并且有可能重建该科的一个假设祖先核型。还能够展示婴猴科动物的染色体与两种懒猴科动物染色体之间的关系。可以提出懒猴形动物染色体进化的总体模式，这是由共同的种群进化以及随后主要是罗伯逊式易位的积累所导致的。在懒猴科的主干中也发生了几次臂间倒位，它们源自这个共同种群。然后，婴猴科各自独立进化，通过主要是罗伯逊式易位的积累；而懒猴科在分化之前积累了臂间倒位。
