Climate change may speed evolution through inherited gene regulation changes

Phys · · 483 words · By Oxford University Press

A study published in Molecular Biology and Evolution suggests that climate change-induced heat stress can accelerate evolution through transgenerational gene regulation changes in fruit flies. The research found that heat shock effects on gene expression and development persisted across generations, particularly in arid populations, potentially facilitating evolutionary adaptation.
