That coffee you slurped this morning? It’s 600,000 years old.
Using genes from coffee plants around the world, researchers built a family tree for the world's most popular type of coffee, known to scientists as Coffea arabica and to coffee lovers simply as “arabica.”
The researchers, hoping to learn more about the plants to better protect them from pests and climate change, found that the species emerged around 600,000 years ago through natural crossbreeding of two other coffee species.
“In other words, prior to any intervention from man,” said Victor Albert, a biologist at the University at Buffalo who co-led the study.
These wild coffee plants originated in Ethiopia but are thought to have been first roasted and brewed primarily in Yemen starting in the 1400s. In the 1600s, Indian monk Baba Budan is fabled to have smuggled seven raw coffee beans back to his homeland from Yemen, laying the foundation for coffee’s global takeover.
Arabica coffee, prized for its smooth and relatively sweet flavor, now makes up 60% - 70% of the global coffee market and is brewed by brands such as Starbucks, Tim Horton's and Dunkin'. The rest is robusta, a stronger and more bitter coffee made from one of arabica's parents, Coffea canephora.
To piece together arabica coffee’s past, researchers studied genomes of C. canephora, another parent called Coffea eugenioides, and more than 30 different arabica plants, including a sample from the 1700s — courtesy of the Natural History Museum in London — that Swedish naturalist Carl Linnaeus used to name the plant.
The study was published Monday in the journal Nature Genetics. Researchers from Nestlé, which owns several coffee brands, contributed to the study.
The arabica plant’s population fluctuated over thousands of years before humans began cultivating it, flourishing during warm, wet periods and suffering through dry ones. These lean times created so-called population bottlenecks, when only a small number of genetically similar plants survived.
Today, that renders arabica coffee plants more vulnerable to diseases like coffee leaf rust, which cause billions of dollars in losses every year. The researchers explored the makeup of one arabica variety that is resistant to coffee leaf rust, highlighting sections of its genetic code that could help protect the plant.
The study clarifies how arabica came to be and spotlights clues that could help safeguard the crop, said Fabian Echeverria, an adviser for the Center for Coffee Research and Education at Texas A&M University who was not involved with the research.
Exploring arabica’s past and present could yield insight into keeping coffee plants healthy – and coffee cups full – for future early mornings.

BEIRUT (AP) — Leaked photographs of the son of Libya’s late dictator Moammar Gadhafi and the tiny underground cell where he has been held for years in Lebanon have raised concerns in the north African nation as Libyan authorities demand improvements.
The photos showed a room without natural light packed with Hannibal Gadhafi’s belongings, a bed and a tiny toilet. “I live in misery,” local Al-Jadeed TV quoted the detainee as saying in a Saturday evening broadcast, adding that he is a political prisoner in a case he has no information about.
Two Lebanese judicial officials confirmed to The Associated Press on Monday that the photographs aired by Al-Jadeed are of Gadhafi and the cell where he has been held for years at police headquarters in Beirut. Gadhafi appeared healthy, with a light beard and glasses.
A person who is usually in contact with Gadhafi, a Libyan citizen, said the photos were taken in recent days. All spoke on condition of anonymity because they were not authorized to speak to media outlets.
Gadhafi has been held in Lebanon since 2015 after he was kidnapped from neighboring Syria, where he had been living as a political refugee. He was abducted by Lebanese militants demanding information about the fate of prominent Lebanese Shiite cleric Moussa al-Sadr, who went missing during a trip to Libya in 1978.
The fate of al-Sadr has been a sore point in Lebanon. His family believes he may still be alive in a Libyan prison, though most Lebanese presume al-Sadr, who would be 95 now, is dead.
A Libyan delegation visited Beirut in January to reopen talks with Lebanese officials on the fate of al-Sadr and the release of Gadhafi. The talks were aimed at reactivating a dormant agreement between Lebanon and Libya, struck in 2014, for cooperation in the probe of al-Sadr. The delegation did not return to Beirut as planned.
The leaks by Al-Jadeed came after reports that Gadhafi was receiving special treatment at police headquarters and that he had cosmetic surgeries including hair transplants and teeth improvements. Al-Jadeed quoted him as saying: “Let them take my hair and teeth and give me my freedom.”
Gadhafi went on a hunger strike in June last year and was taken to a hospital after his health deteriorated.
Libya’s Justice Ministry in a statement Sunday said Gadhafi is being deprived of his rights guaranteed by law. It called on Lebanese authorities to improve his living conditions to one that “preserves his dignity," adding that Lebanese authorities should formally inform the ministry of the improvements. It also said Gadhafi deserves to be released.
After he was kidnapped in 2015, Lebanese authorities freed him but then detained him, accusing him of concealing information about al-Sadr’s disappearance.
Al-Sadr was the founder of the Amal group, a Shiite militia that fought in Lebanon’s 1975-90 civil war and later became a political party that is currently led by the country’s Parliament Speaker Nabih Berri.
Many of al-Sadr’s followers are convinced that Moammar Gadhafi ordered al-Sadr killed in a dispute over Libyan payments to Lebanese militias. Libya has maintained that the cleric, along with two traveling companions, left Tripoli in 1978 on a flight to Rome.
Human Rights Watch issued a statement in January calling for Gadhafi’s release. The rights group noted that Gadhafi was only 2 years old at the time of al-Sadr’s disappearance and held no senior position in Libya as an adult.
