How Did Humans Domesticate Tomatoes?

The wild ancestor of every tomato on Earth is a weedy roadside plant from the Andes whose fruit weighs about one gram. A modern beefsteak can weigh a kilogram, and unlike almost any other crop, we can name the exact gene we switched off to ruin its flavour, the decade it happened, and why.
What You Will Learn in This Video:
The Thousand-Fold Fruit: How Solanum pimpinellifolium, a peppercorn-sized wild berry, was scaled up 1,000 times, and how Anne Frary's 2000 cloning of fw2.2 explained nearly a third of that jump on its own.
Two Domestications, 4,000 Kilometres Apart: Why the ancestor grows in Peru but the finished tomato comes from Mexico, and how Razifard's 2020 genomic study uncovered a partial domestication in the Andes, a feral reversal during the migration north, and a second, harder domestication in Mesoamerica.
The Name That Never Got Corrected: How the Nahuatl word tomatl actually belonged to the tomatillo, how the Spanish attached it to the wrong fruit, and how the plant that owned the name ended up being called "little tomato" in English.
Europe's Two-Century Refusal: Why nightshade suspicion kept the tomato an ornamental curiosity from the 1540s until Antonio Latini's 1692 sauce recipe, and an honest look at whether the famous pewter-plate lead-poisoning story holds up.
The Gene We Switched Off: How the uniform ripening mutation disabled SlGLK2, stripped chloroplasts out of the fruit's shoulder, and cost it measurable sugar and flavour compounds, a trade-off nobody understood for eighty years until Ann Powell's 2012 Science paper.
Bred for the Machine: How the end of the Bracero programme in 1964 pushed UC Davis to engineer both a mechanical harvester and the tough, thick-skinned VF-145 tomato built to survive it, redesigning the crop to serve the technology.
Putting It Back: Harry Klee's work breeding the lost flavour alleles back into commercial lines, and the 2018 gene-editing experiments that domesticated wild tomatoes from scratch in a handful of generations.
