5. Conclusion
In summary, our comparative transcriptome analyses of the brain, liver, and cochlear in the macrotis group provided the theoretical basis for the adaptive mechanism in the evolution of specieslow. The evidence of genetic adaptation provides insights into hearing related genetic adaptation, visual related genetic adaptation and energy metabolism related genetic adaptation. And GO enrichment analysis revealed that PSGs detected in the specieslow mainly enriched in GO terms related to energy metabolism. The important genes and mutations selected may be of great significance for the bat adaptability. While more detailed functional studies of all the selected candidate genes will be necessary to confirm the roles of individual genes. Studying the function and potential pathways of these genes will contribute to a better understanding of phenotypic evolution in bats, espically for the evolution of bat acoustic. Further study of specieslow will play an important role in understanding of their adaptive ev olution mechanisms.
