Genetic diversity is a fundamental component of biodiversity. We outline and test three distinct macroecological drivers of intraspecific genetic diversity, identify global patterns, and assess the congruence of these relationships across the genome to help provide a more complete understanding of how evolutionary forces contribute to biodiversity at multiple scales. Overall, we reveal how environmental variables can influence mutation rates and genetic drift in the ocean, caution against using mitochondrial macrogenetic patterns as proxies for whole‐genome diversity, and aid in defining global gradients of genetic diversity.
