Epigenetic changes don't last

Scientists discovered that epigenetic modifications in plants, such as DNA methylation, are unstable and often disappear after a few generations. These changes can occur frequently but usually do not contribute significantly to long-term evolution.

If insurance companies pay out too often, farmers will be threatened with ruin in the long term

A new study found that rain-index insurance can have ecological consequences if farmers adopt unsustainable grazing practices. The study suggests that insurance payouts in periods of moderate drought may incentivize farmers to abandon sustainable management strategies, leading to overgrazing and increased soil erosion. To mitigate thes...
