Exact excerpt

Here we conduct a long-term evolution experiment with the marine diatom Chaetoceros muelleri, comparing abrupt and gradual CO2 increases from 440 to 1000 ppm over 1100 generations. ... abrupt acidification exaggerates diatom growth and carbon fixation responses by up to 15%, driven by enhanced divergent genomic signals and persistent gene expression changes. Gradual acidification elicits weaker phenotypic and genomic shifts, aligning more closely with natural ocean conditions.
