The relatively new techniques of molecular phylogenetics have also shed light on some aspects of mammalian evolution by estimating the timing of important divergence points for modern species. When used carefully, these techniques often, but not always, agree with the fossil record.

We investigated global speciation-rate variation across crown Mammalia using a novel time-scaled phylogeny (N=5,911 species, ~70% with DNA), finding that trait- and latitude-associated speciation has caused uneven species richness among groups. We identify 24 branch-specific shifts in net diversification rates linked to ecological traits.

Recent palaeontological discoveries and the correspondence between molecular and morphological results provide fresh insight on the deep structure of mammalian phylogeny. This new wave of...

2021年12月22日 · Here we develop a Bayesian molecular-clock dating approach to estimate a timetree of 4,705 mammal species integrating information from 72 mammal genomes. We show that increasingly larger...

2019年12月4日 · Our “backbone-and-patch” approach to tree building applies a newly assembled 31-gene supermatrix to two levels of Bayesian inference: (1) backbone relationships and ages among major lineages, using fossil node or tip dating, and (2) species-level “patch” phylogenies with nonoverlapping in-groups that each correspond to one representative lineage...

2023年4月27日 · Foley’s efforts in the research produced the world’s largest mammalian phylogenetic tree to date. The “mammalian tree of life” maps out the evolution of mammals over more than 100 million years and is crucial to the goals of the Zoonomia Project.

2011年3月28日 · Phylogenetic trees of present-day species allow investigation of the rate of evolution that led to the present-day diversity. A recent analysis of the mammalian phylogeny challenged the view of explosive mammalian evolution after the Cretaceous–Tertiary (K/T) boundary (65 Mya).

2011年9月9日 · The overall shape of mammalian phylogeny is complex, reflecting a mixture of diversification rates. The next section is to identify clades that stand out as unusual compared with the tree as a whole.

Four major branches of the mammals are defined below: Xenarthra (indicated in magenta): a group once included in the order Edentata (anteaters, armadillos and sloths). Euarchontoglires (indicated in blue): a group that includes the Primates and the Glires (Rabbits + …

1992年4月1日 · It provides a complete listing of mammalian diversity over time and space, and evaluates the effect of biogeography and climatic change on evolutionary patterns and faunal transitions, with the...
