| This hypothesis recognized differences between microbats and megabats and acknowledged that flight has only evolved once in mammals. |
| As the bodies of some microbats have distinct coloration, they may be able to discriminate colours. |
| However genetic data now indicate that the rhinolophoid microbats are in fact more closely related to megabats than to other microbats. |
| Most of the oldest known bat fossils were already very similar to modern microbats. |
| Genetic evidence indicates that megabats originated during the early Eocene and should be placed within the four major lines of microbats. |
| Most megabats roost with the head tucked towards the belly, whereas most microbats roost with the neck curled towards the back. |
