摘要
The fossil record provides the only direct evidence of changes in 生物多樣性 over time. Patterns in more inclusive taxonomic levels (e.g., families and orders) often become more complex because of interactions between 生物 traits and environmental conditions across different 演化ary lineages. Using supercomputing and 人工智慧 algorithms, we analyzed a high-resolution global dataset of fusuline foraminifera-the most diverse 海洋 fossil group from the Carboniferous to the Permian (similar to 340 to 252 million years ago)-at an unprecedented temporal resolution of <45 thousand years. Our unbinned 多樣性 reconstruction reveals unexpectedly simple 多樣性 dynamics in this exceptionally well-preserved clade. We identify two (and likely a third) truncated exponential diversifications and four major 多樣性 declines. Durin
