A study reveals that sticklebacks with complete bony plates have survival rates several percentage points higher than those with reduced plates, indicating ongoing natural selection. Moreover, the strength of selection appears to have intensified between 2016 and 2022. These findings, published in Evolution, demonstrate that natural selection can drive rapid evolution in natural populations.
