Molecular revolution in bat phylogenetics (1997–2010)
DNA sequencing revealed that fruit bats and some echolocating bats form a lineage called Yinpterochiroptera, while most echolocating bats belong to Yangochiroptera. This overturned the traditional Microchiroptera/Megachiroptera split and showed echolocation evolved multiple times.
Researchers adopted the two-suborder classification (Yinpterochiroptera and Yangochiroptera).
It set up the next question: where and when did the ancestral bat lineage arise? Later studies variously proposed North America, Africa, or Asia.
The 2026 study uses far more genomic data and fossil integration to answer the origin question that molecular phylogenetics raised but could not resolve.
