These minerals in turn may have spurred nutrient cycling in the oceans, boosting the metabolism of microbial life. <br><a href="https://arstechnica.com/science/2025/02/bulldozing-glaciers-may-have-spurred-evolution-in-the-ocean/" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">arstechnica.com/science/2025/0</span><span class="invisible">2/bulldozing-glaciers-may-have-spurred-evolution-in-the-ocean/</span></a></p>
