Malus sieversii modern apple cultivars. Unlike domesticated varieties its leaves go red in autumn: 62.2% of the trees in the wild do this compared to only 2.8% of the regular apple plant or the 2,170 English cultivated varieties. The species is now considered vulnerable to extinction. "Malus sieversii" has previously been identified as the main contributor to the genome of the cultivated apple ("Malus pumila"), on the basis of morphological, molecular, and historical evidence. A DNA analysis in 2010 confirmed "M. sieversii" as the progenitor of the cultivated apple. A third species that has been thought to have made contributions to the
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
