European wild apple's genetic contribution (2012)
A PLOS Genetics study analyzed 839 apple accessions from China to Spain and showed that the European wild apple (Malus sylvestris) was a major secondary contributor to the domesticated apple genome, alongside the Central Asian Malus sieversii.
The finding overturned the idea that apples were domesticated in a single event.
It showed wild European apples interbred with cultivated varieties over centuries, shaping modern apple genetics.
The genetic mixing that produced modern apples also produced founder trees like Drap d'Or. Understanding that history helps researchers trace which traits came from where.
