A decade-long study in China reveals that rice plants can inherit cold tolerance through epigenetic changes rather than DNA alterations. This research, published in Cell, demonstrates that environmental factors can induce heritable modifications in plants. The study provides a mechanism for epigenetic changes, reinforcing the notion that evolution involves more than just gradual DNA mutations. Experts agree that this study challenges traditional views on evolution and highlights the active role of the environment in shaping adaptations in rice plants, which originally thrived in warmer climates.
What they're showing is extremely convincing; I would say that it's a landmark in the field, highlighting how environmental pressures induce heritable changes without affecting DNA.
This study shows that the environment isn't just a passive actor in evolution; rather, it's a selective force inducing a targeted change in plants.
