2007年10月10日 · Despite the rising interest in homeotic genes, little has been known about the course and pattern of evolution of homeotic traits across the mammalian radiation. An array of …

2024年5月30日 · Our results show that, on average, about 34% of therian diversity survived the K-Pg boundary (comparison at 67 and 65 Myr ago), with an average pre–K-Pg boundary …

2016年6月15日 · It is often postulated that mammalian diversity was suppressed during the Mesozoic Era and increased rapidly after the Cretaceous–Palaeogene (K–Pg) extinction …

2021年7月12日 · Mesozoic mammaliaforms document the first two-thirds of mammalian evolution and exhibited great ecomorphological diversity, including fossorial, arboreal, aquatic, gliding, …

While the origin of mammals has provided one set of puzzles, the diversification of mammals is also ripe with questions. Three extant major groups of mammals exist. Monotremes retain …

2016年6月15日 · In contrast with the suppression hypothesis, our results suggest that an ecomorphological diversification of therians began 10-20 Myr prior to the K–Pg extinction …

2007年10月10日 · Clusters of homeotic transformations mark the emergence point of mammals in the Triassic and the radiation of therians in the Cretaceous. A cluster of homeotic changes in …

2007年2月1日 · Five major gradient modification sets are identified: (1)--quantitative changes of primary segmental identity pattern that appeared at the origin of the tetrapods ; (2)--frame shift …

Brocklehurst et al. report that Mesozoic therians evolved under greater morphological constraint than contemporary mammaliaforms. This constraint was released later than the extinction of …

2019年10月1日 · There are three main periods of ecological diversification (Early–Middle Jurassic, Late Cretaceous, and Paleogene), each involving radiations of multiple mammalian …
