Malus sylvestris to most European countries. It occurs in a scattered distribution pattern as single individuals or in small groups. In the past "M. sylvestris" was thought to be the most important ancestor of the cultivated apple ("M. pumila"), which has since been shown to have been originally derived from the central Asian species "M. sieversii". However another recent DNA analysis confirms that "M. sylvestris" has contributed significantly to the genome. The study found that secondary introgression from other species of the genus "Malus" has greatly shaped the genome of "M. pumila", with "M. sylvestris" being the largest secondary contributor.

Egyptian fruit bat Egyptian fruit bat The Egyptian fruit bat or Egyptian rousette ("Rousettus aegyptiacus") is a species of Old World fruit bat. Étienne Geoffroy Saint-Hilaire originally gave this species the specific name of "egyptiacus" in 1810, but he later revised it to "ægyptiacus". In 1992, G. B. Corbet and J. E. Hill argued that this revision was invalid and changed the name back to "egyptiacus"; the 1999 "Mammalian Species" review used "egyptiacus" as well. However, Geoffroy's revision was argued to be valid in 2001 by D. Kock. He notes that the second spelling was "accepted almost universally by the scientific community", including
