番茄如此酸甜可口,它的“老家”在哪里呢?研究人员在南美洲最南部的巴塔哥尼亚地区发现了两块5220万年前的化石,它们很可能属于番茄早期的亲缘植物,与现在的番茄同属茄科。这表明,番茄的祖先很可能生长在5000多万年前的南极洲附近。这两块化石具有扁平的轮廓,表面纹理清晰可见,内部果实虽然已经转化为黑色的煤炭,但仍然保存完整。这是发现的世界上第一批茄科植物
Where is tomato so sweet and sour? Two researchers found 52.2 million years ago in the Patagonian region of southernmost South America, most likely belonging to the early kinship of tomatoes Plants, belong to the same family of Solanaceae nowadays. This shows that tomato ancestors are likely to grow more than 50 million years ago, near Antarctica. The two fossils have a flat profile and the surface texture is clearly visible. Although the internal fruit has been transformed into black coal, it remains intact. This is the first batch of solanaceae found in the world
