Abstract

Introduction

Comparative Anatomy describes the similarities and differences in the anatomy of different species, Comparative anatomical studies does not only provide evidence for evolution but indicates that various organisms originate from a common ancestor and assists scientists in classifying these organisms based on similar characteristics of their anatomical structure. Materials and Methods

 Approval was obtained from ethical committee of the Department of Human Anatomy and Cell Biology, Delta State University Abraka, reference number (DELSU/CHS/ANA/68/85). The animals were grouped into three based on their dietary patterns: Herbivores (Capra aegagrus &Bostourus), Carnivores (Canis lupus & Felis catus) and Omnivores (Rattus norvegicus &Sus scrofa), a renal tissue were obtained from each of the studied species and preserved in 10% formal saline for one week. The tissues were subsequently processed and stained using general and specific histochemical techniques.

Observation   

It was observed from this study all the mammalian kidneys consisted of similar histological features which explained that these studied mammals undergo the same evolutionary trend, adaptational changes and phylogenic relaionship that exist between the kidneys of the studied species.

 Conclusion

Despite their differences in dietary patterns, the studied species have similar histological features with little observed variation. However, they have little differences in histochemical staining pattern for glycogen and glycoprotein but in reticulin they all stain intensely. This study has established a strong relationship in the histology of the kidney in six mammalian species.
