A closer look
Darwin's evolutionary rules get totally bypassed when a plant decides to rewrite its own genetic software. The common toadflax can radically change its petal structure from standard symmetry to a mutant star-shape, a state that gets passed down through generations. Yet, their raw DNA sequence remains utterly identical. Instead, the plant attaches chemical methyl groups to specific genes, physically blocking them from being read—proving that environmental trauma can be inherited without a single actual genetic mutation.
