Evolution’s second driver: Lamarckism makes a comeback alongside natural selection

Biologists are revisiting Lamarck’s idea that traits acquired during life can be passed to offspring, supported by epigenetic and transgenerational evidence in species like C. elegans and rice. The article argues Lamarckian mechanisms can operate alongside natural selection, not replace it, with implications for agriculture, conservation, and our understanding of human traits, suggesting an updated, integrated evolutionary framework.
