Editing Megabat (section)

===Genome size===
Like all bats, megabats have much smaller [[genome]]s than other mammals. A 2009 study of 43 megabat species found that their genomes ranged from 1.86 picograms (pg, 978 Mbp per pg) in the straw-colored fruit bat to 2.51 pg in [[Lyle's flying fox]] (''Pteropus lylei''). All values were much lower than the mammalian average of 3.5 pg. Megabats have even smaller genomes than microbats, with a mean weight of 2.20 pg compared to 2.58 pg. It was speculated that this difference could be related to the fact that the megabat lineage has experienced an extinction of the [[LINE1]]—a type of [[long interspersed nuclear element]]. LINE1 constitutes 15–20% of the human genome and is considered the most prevalent long interspersed nuclear element among mammals.<ref>{{cite journal|doi=10.1098/rsbl.2009.0016|pmid=19324635|pmc=2679926|title=The genome sizes of megabats (Chiroptera: Pteropodidae) are remarkably constrained|journal=[[Biology Letters]]|volume=5|issue=3|pages=347–351|year=2009|last1=Smith|first1=J.
