Basic reporting

In the present investigation, the authors have shown how that morphological variation in the GI tract of humans and other species is associated with each organ’s role in food processing. They have done a basic, extensive, informative, and detailed about inter-species and within-species variations.

Experimental design

The experiment is well-designed and executed, and the manuscript is well-written. However, there are specific observations and suggestions from the side to improve the quality of the manuscript.

Validity of the findings

Data has been presented well with the help of graphs and tables.

Additional comments

1. Introduction: Extensively written and justifies the very purpose of the said experiment. But that could be made more concise, and much of the review part could be used in discussion or should be presented in tabular form.
2. Results: Drawings or original pictures of the organs in the study of various species with labeling will also help the readers in general about the gross morphological variations.
3. Abstract: If the authors could provide a graphical abstract of the manuscript, it would improve the overall understanding of the
