However, there have been other views, and a vigorous debate persists to this date.

For example, in the 1980s and 1990s, some researchers proposed ( based primarily on the similarity of the visual pathways ) that the Megachiroptera were in fact more closely affiliated with the primates than the Microchiroptera, with the two groups of bats having therefore evolved flight via convergence ( see Flying primates theory ).

However, a recent flurry of genetic studies confirms the more longstanding notion that all bats are indeed members of the same clade, the Chiroptera.

Other studies have recently suggested that certain families of microbats ( possibly the horseshoe bats, mouse-tailed bats and the false vampires ) are evolutionarily closer to the fruit bats than to other microbats.
