Exafroplacentalia

exafroplacentalia
Magnorder Boreoeutheria:

  • Superorder Laurasiatheria:
    • Eulipotyphla Shrews, Moles
    • Cetartiodactyla Whales, dolphins, ruminants, etc
    • Chiroptera Bats
    • Perissodactyla Horses, etc
    • Pholidota Pangolins
    • Carnivora Carnivores
  • Superorder Euarchontoglires:
    • Glires
      • Rodentia Rodents
      • Lagomorpha Rabbits, etc
    • Euarchonta
      • Scandentia Tree Shrews
      • Primatomorpha
        • Dermoptera Flying Lemurs
        • Primates

Exafroplacentalia or Notolegia is a clade of placental mammals proposed in 2001 on the basis of molecular research[1][2]

Exafroplacentalia places Xenarthra as a sister group to the Boreoeutheria comprising Laurasiatheria and Euarchontoglires,[3] thus making Afrotheria a primitive group of placental mammals the group name roughly means "those which are not African placentals"

Classification

Eutheria  


Afrotheria


  Exafroplacentalia  


Xenarthra


  Boreoeutheria  

   

Laurasiatheria


   

Euarchontoglires





Alternative hypotheses

One alternative hypothesis is the Epitheria hypothesis:

Placentalia


Xenarthra


Epitheria


Afrotheria


Boreoeutheria


Euarchontoglires



Laurasiatheria





Another alternative hypothesis is the Atlantogenata hypothesis:

Eutheria

Atlantogenata


Xenarthra



Afrotheria



Boreoeutheria


Euarchontoglires



Laurasiatheria




Updated analysis of transposable element insertions around the time of divergence strongly supports the fourth hypothesis of a near-concomitant origin of the three superorders of mammals:[4]

Eutheria


Xenarthra



Afrotheria


Boreoeutheria


Euarchontoglires



Laurasiatheria
