...Using population genomic modeling methods, the researchers determined that C. arabica evolved as a result of natural hybridization between two other species of coffee: C. eugenioides and C. canephora. The hybridization resulted in a polyploid genome, meaning each offspring contains two sets of chromosomes from each parent. This may have given C. arabica a survival advantage that enabled it to thrive and adapt...
The researchers acknowledge that there is a margin of error. Earlier estimates of the time of hybridization date it as recently as 10,000 years ago.
"We had to input an estimated mutation rate, and a generation time (seed to seed time). Together, these assumptions allow us to convert to calendar years. But these estimates are of course fraught with error ranges given the usual uncertainty on mutation rates and generation times," Albert said. Still, he thinks their estimate is reasonably accurate. The researchers used genetic information from 41 samples of C. arabica from various locations, including an 18th-century specimen...
In 1927, C. arabica naturally crossed back to one of its parent species, C. canephora, on the island of Timor. This event created a more rust-resistant variety of coffee, but the quality of the beans has been deemed inferior to those produced by C. arabica or Robusta — another name for C. canephora.

and some AGW agitprop:(Image: fabiomax / Adobe Stock)Is coffee going extinct? Here's how it could impact you | Chris Clarke | April 30, 2024
Couldn’t have been a million years ago. My neighbor insists the earth was less than 10,000 years old.
Regards,
If it’s all part of random cross mating, does that put coffee on the LGBTQ spectrum?
Pure fiction. Making stuff up, calling it science and research and getting paid for it.
I just got back from a ministry weekend and 3 days of Folgers. I couldn’t wait to get home to good coffee.
Spend more time with your neighbor. Listen to him.
Too bad the coffee plant couldn’t mate-up with the coca plant.
Nice work if you can get it!.....................
Your link about coffee going extinct scared me!
Until I read the story and saw the part about “global warming” being to blame.
Now I’m not so worried.
2 plants randomly mated up to 1 million years ago to give rise to one of the world’s most popular drinks [coffee]

2 coffee plants randomly mated up to 1 million years ago to give rise to another coffee plant.
sniker science
:^)
Your post is pure fiction, I’m sure that happens a lot.
Years ago Jolt Cola and a bunch of unkempt programmers got together and created Java, so, it happens now and then.
So, it wasn't the best part of waking up? :^)
:^D
Rubusta as grown in Việt Nam( and likely in Timor also but I have not experienced Timor coffee) is the best coffee anywhere except for the Kona of Hawaii.
