The seminar which was conducted in a hybrid manner received great enthusiasm from the participants, lecturers, alumni, and presenters. The topics discussed have an interesting breakthrough value for the world of biology, especially in understanding the correlation between systematics, evolution, and phylogeography which is associated with an increase in studies in genetics. The enthusiasm of the participants was evident from the many questions posed by participants who had different backgrounds. The speaker raised this topic by presenting the results of his research on bats (Chiroptera) which is the second order that has the most diversity of species in it after Rodentia.

Along with further research in systematics, several obstacles were encountered such as the presence of cryptic species, species restrictions, and failures in species differentiation, causing systematics in the animal kingdom to become more complex. This requires more complex data such as to determine which taxa in a species are cryptic. In this seminar, further studies of cryptic species were clearly presented in bat species that have the same morphology with different echolocation frequencies or in bats that have different morphology with the same echolocation.

This Guest Lecture Seminar activity that has been carried out provides revolutionary motivation and many new ideas emerge for other researchers in their work. As the times progress, of course, it is necessary to develop studies in biology by utilizing new methods, applications, and ideas in order to be able to reveal many things that are still a mystery to this day.
