Thanks to recent scientific advances, a group of researchers has elucidated the origin of this essential plant. The study of DNA from a variety of plants has allowed scientists to trace the complex history of the potato, revealing that it is not the product of linear evolution, but of an improbable hybridization between different plant species. This discovery marks a significant step forward in our understanding of plant evolution.<\/p>\n<div class=\"code-block code-block-4\" style=\"margin: 8px 0; clear: both;\">\n<\/div>\n<h2>An Evolutionary Enigma Finally Resolved<\/h2>\n<p>For decades, botanists have pondered the links among tomatoes, potatoes, and a mysterious group of plants known as Etuberosum. Although all belong to the nightshade family, their relationships remained unclear. The team led by Sandra Knapp, from the Natural History Museum in London, used advanced genomic technologies to analyze the DNA of 128 specimens representing these lineages. It turned out that the modern potato is the product of hybridization between the ancestors of wild tomatoes and those of Etuberosum, rather than a species that evolved in isolation.<\/p>\n<blockquote class=\"wp-embedded-content\" data-secret=\"15VGDzqBnF\">\n<p>\u201cThese Time-Defying Molecules\u201d: how proteins, far more resilient than DNA, could reshape our understanding of the dinosaur history<\/p>\n<\/blockquote>\n<p><iframe loading=\"lazy\" class=\"wp-embedded-content\" sandbox=\"allow-scripts\" security=\"restricted\" style=\"position: absolute; visibility: hidden;\" title=\"\u00ab\u00a0\u00ab Ces mol\u00e9cules d\u00e9fiant le temps \u00bb : comment les prot\u00e9ines, bien plus r\u00e9sistantes que l\u2019ADN, pourraient bouleverser notre compr\u00e9hension de l\u2019histoire des dinosaures\u00a0\u00bb \u2014 VivreDemain.fr\" src=\"https:\/\/vivredemain.fr\/2025\/08\/05\/un-hasard-ancestral-a-faconne-il-y-a-8-millions-dannees-laliment-cle-qui-nourrit-des-milliards-dhumains-aujourdhui-une-verite-qui-divise-les-experts\/about:blank\" data-secret=\"15VGDzqBnF\" width=\"600\" height=\"338\" frameborder=\"0\" marginwidth=\"0\" marginheight=\"0\" scrolling=\"no\" data-rocket-lazyload=\"fitvidscompatible\" data-lazy-src=\"https:\/\/vivredemain.fr\/2025\/07\/28\/ces-molecules-defiant-le-temps-comment-les-proteines-bien-plus-resistantes-que-ladn-pourraient-bouleverser-notre-comprehension-de-lhistoire-des-dinosaures\/embed\/#?secret=Q4j9kONXl5#?secret=15VGDzqBnF\"><\/iframe><noscript><iframe class=\"wp-embedded-content\" sandbox=\"allow-scripts\" security=\"restricted\" style=\"position: absolute; visibility: hidden;\" title=\"\u00ab\u00a0\u00ab Ces mol\u00e9cules d\u00e9fiant le temps \u00bb : comment les prot\u00e9ines, bien plus r\u00e9sistantes que l\u2019ADN, pourraient bouleverser notre compr\u00e9hension de l\u2019histoire des dinosaures\u00a0\u00bb \u2014 VivreDemain.fr\" src=\"https:\/\/vivredemain.fr\/2025\/07\/28\/ces-molecules-defiant-le-temps-comment-les-proteines-bien-plus-resistantes-que-ladn-pourraient-bouleverser-notre-comprehension-de-lhistoire-des-dinosaures\/embed\/#?secret=Q4j9kONXl5#?secret=15VGDzqBnF\" data-secret=\"15VGDzqBnF\" width=\"600\" height=\"338\" frameborder=\"0\" marginwidth=\"0\" marginheight=\"0\" scrolling=\"no\"><\/iframe><\/noscript><\/p>\n<div class=\"code-block code-block-1\" style=\"margin: 8px 0; clear: both;\">\n<\/div>\n<h2>A Miraculous Hybridization in the Primitive Andes<\/h2>\n<p>About 8 to 9 million years ago, the Andean cordillera underwent major geological transformations. It was within this changing environment that two distinct plant species crossed paths. Although they had diverged from a common ancestor millions of years earlier, they retained enough genetic compatibility to reproduce. Thus, a single hybrid emerged: the ancestor of modern potatoes. Genomic analysis revealed this intricate kinship in mosaic patterns, reflecting the intermingling of the genetic legacies of its parents.<\/p>\n<blockquote class=\"wp-embedded-content\" data-secret=\"vxQUywu3FJ\">\n<p>\u201cMars, This Lost Planet\u201d: discover how Earth miraculously escaped a sterile and hostile fate thanks to fascinating invisible forces<\/p>\n<\/blockquote>\n<p><iframe loading=\"lazy\" class=\"wp-embedded-content\" sandbox=\"allow-scripts\" security=\"restricted\" style=\"position: absolute; visibility: hidden;\" title=\"\u00ab\u00a0\u00ab Mars, cette plan\u00e8te perdue \u00bb : d\u00e9couvrez comment la Terre a miraculeusement \u00e9chapp\u00e9 \u00e0 un destin st\u00e9rile et hostile gr\u00e2ce \u00e0 des forces invisibles fascinantes\u00a0\u00bb \u2014 VivreDemain.fr\" src=\"https:\/\/vivredemain.fr\/2025\/08\/05\/un-hasard-ancestral-a-faconne-il-y-a-8-millions-dannees-laliment-cle-qui-nourrit-des-milliards-dhumains-aujourdhui-une-verite-qui-divise-les-experts\/about:blank\" data-secret=\"vxQUywu3FJ\" width=\"600\" height=\"338\" frameborder=\"0\" marginwidth=\"0\" marginheight=\"0\" scrolling=\"no\" data-rocket-lazyload=\"fitvidscompatible\" data-lazy-src=\"https:\/\/vivredemain.fr\/2025\/07\/26\/mars-cette-planete-perdue-decouvrez-comment-la-terre-a-miraculeusement-echappe-a-un-destin-sterile-et-hostile-grace-a-des-forces-invisibles-fascinantes\/embed\/#?secret=TwBcKkcKaF#?secret=vxQUywu3FJ\"><\/iframe><noscript><iframe class=\"wp-embedded-content\" sandbox=\"allow-scripts\" security=\"restricted\" style=\"position: absolute; visibility: hidden;\" title=\"\u00ab\u00a0\u00ab Mars, cette plan\u00e8te perdue \u00bb : d\u00e9couvrez comment la Terre a miraculeusement \u00e9chapp\u00e9 \u00e0 un destin st\u00e9rile et hostile gr\u00e2ce \u00e0 des forces invisibles fascinantes\u00a0\u00bb \u2014 VivreDemain.fr\" src=\"https:\/\/vivredemain.fr\/2025\/07\/26\/mars-cette-planete-perdue-decouvrez-comment-la-terre-a-miraculeusement-echappe-a-un-destin-sterile-et-hostile-grace-a-des-forces-invisibles-fascinantes\/embed\/#?secret=TwBcKkcKaF#?secret=vxQUywu3FJ\" data-secret=\"vxQUywu3FJ\" width=\"600\" height=\"338\" frameborder=\"0\" marginwidth=\"0\" marginheight=\"0\" scrolling=\"no\"><\/iframe><\/noscript><\/p>\n<div class=\"code-block code-block-1\" style=\"margin: 8px 0; clear: both;\">\n<\/div>\n<h2>The Breakthrough That Changed Everything: The Tuber<\/h2>\n<p>The hybridization brought forth a novel trait: the formation of tubers. Unlike tomatoes and Etuberosum, the new plant could develop these underground, nutrient-rich organs. Researchers identified the genes responsible for this phenomenon. The SP6A gene, derived from tomatoes, was modified in the potato to regulate the tuberization process. The IT1 gene, originating from Etuberosum, also contributes to the creation of these crucial stores.
