Radiation of extant marsupials after the K/T boundary: Evidence from complete mitochondrial genomes
(2003) In Journal of Molecular Evolution 57(Suppl. 1). p.3-12- Abstract
- The complete mitochondrial (mt) genomes
of five marsupial species have been sequenced.
The species represent all three South American orders
(Didelphimorphia, Paucituberculata, and Microbiotheria).
Phylogenetic analysis of this data set indicates
that Didelphimorphia is a basal marsupial lineage
followed by Paucituberculata. The South American
microbiotherid Dromiciops gliroides (monito del
monte) groups with Australian marsupials, suggesting
a marsupial colonization of Australia on two
occasions or, alternatively, a migration of an Australian
marsupial lineage to South America. Molecular
estimates suggest that the deepest... (More) - The complete mitochondrial (mt) genomes

estimates suggest that the deepest marsupial
divergences took place 64–62 million years before
present (MYBP), implying that the radiation of recent
marsupials took place after the K/T (Cretaceous/
Tertiary) boundary. The South American marsupial
lineages are all characterized by a putatively nonfunctional
tRNA for lysine, a potential RNA editing
of the tRNA for asparagine, and a rearrangement of
tRNA genes at the origin of light strand replication. (Less)
