This is what researchers write in the journal Nature Genetics . Their study concerns Coffea arabica : the coffee plant that produces about 60 percent of all coffee products produc worldwide. This makes it by far the most popular type of coffee in the world. Which – funnily enough, it now turns out – originat without human intervention. The researchers draw this conclusion after delving into the genome of Coffea arabica again in order to map its history – and future – more accurately.
Ancient cross
It has long been known that Coffea arabica is actually a cross between two other coffee species: Coffea canephora and Coffea eugenioides . But when these two cross and Coffea arabica saw the light of day was unclear. The new research phone number library can provide some clarity in this regard and reveals that Coffea arabica must have originat somewhere between 610,000 and 1 million years ago. “In other words, the cross that produc Arabica was not human,” concludes researcher Victor Albert. “It is quite clear that this cross occurr before modern humans emerg and coffee was cultivat.”
Yemen
Coffee cultivation only really start around the fifteenth century. And bas on their study, the researchers also Защо централизираните данни са важни за успеха на застрахователната агенция think they know where it all start. Namely in the area around Yemen. Baba Buda who is said to have smuggl some coffee beans from Yemen to India in the seventeenth century. After which coffee was also grown in that country. “It seems that the diversity of coffee that was deb directory known in Yemen is the basis for the current diversity of coffee. Says researcher Patrick Descombes. “Coffee is not a crop that was cross a lot. Like corn and wheat, for example, to obtain new varieties. People chose a variety that they lik and start growing it. So the varieties that we know today have probably been around for a very long time.”
