Overall Contribution

Core Achievement Key Details & Impact

Replaced misleading morphology-based classification with a robust genetic framework.

New Framework Key Details & Impact

Built around the four superorders: 1. Afrotheria 2. Xenarthra 3. Laurasiatheria 4. Euarchontoglires

Major Revelation Key Details & Impact

Exposed rampant evolutionary convergence 

(unrelated species evolving similar traits,

which misled morphology-based trees).

Resolution of the Placental Root Key Details & Impact

Strongly supports the Atlantogenata hypothesis 

(Afrotheria + Xenarthra

as the earliest placental mammal split).

Timing of Major Radiation Key Details & Impact

Links the diversification of modern placental orders to the post-K-Pg (post-dinosaur) world, following the Cretaceous-Paleogene mass extinction (~66 million years ago).

Overall Contribution Key Details & Impact

Provided a coherent, evidence-based narrative for the origin and rise of modern mammal
