- Mammoth and elephant phylogenetic relationships
Forlagets udgivne version, 248 KB, PDF-dokument
At the morphological level, the woolly mammoth has most often been considered as the sister-species of Asian elephants, but at the DNA level, different studies have found support for proximity with African elephants. Recent reports have increased the available sequence data and apparently solved the discrepancy, fi nding mammoths to be most closely related to Asian elephants. However, we demonstrate here that the three competing topologies have similar likelihood, bayesian and parsimony supports. The analysis further suggests the inadequacy of using Sirenia or Hyracoidea as outgroups. We therefore argue that orthologous sequences from the extinct American mastodon will be required to defi nitively solve this long-standing question.
