We provide a comprehensive phylogenetic analysis of genetic variation across an alignment of 241 placental mammal genome assemblies, addressing prior concerns regarding limited genomic sampling across species. We compared neutral genome-wide phylogenomic signals using concatenation and coalescent-based approaches, interrogated phylogenetic variation across chromosomes, and analyzed extensive catalogs of structural variants. Interordinal relationships exhibit relatively low rates of phylogenomic conflict across diverse datasets and analytical methods. Conversely, X-chromosome versus autosome conflicts characterize multiple independent clades that radiated during the Cenozoic. Genomic time trees reveal an accumulation of cladogenic events before and immediately after the Cretaceous-Paleogene (K-Pg) boundary, implying important roles for Cretaceous continental vicariance and the K-Pg extinction in the placental radiation.", "doi": "10.1126/science.abl8189", "pmid": "37104581", "labels": [], "xrefs": [{"db": "mid", "key": "NIHMS1897334"}, {"db": "pmc", "key": "PMC10233747"}], "notes": [], "created": "2026-09-23T06:48:29.906Z", "modified": "2026-09-23T06:48:30.145Z"}
