How plump organic tomatoes were created using ancient genetic engineering

If you like big, juicy tomatoes you can thank a mutation in the Cell Size Regulator (CSR) gene that occurred during the tomato domestication process thousands of years ago. it's no secret that ancient people genetically engineered vegetables to be larger and have more calories - food was scarce. When humans first began cultivating the wild tomato in the Andean mountain regions of Ecuador and Northern Peru, they continually engaging in such artificial selection.
