Molecular systematics: Perfect SINEs of evolutionary history?
Short interspersed repetitive elements - SINEs - are being championed as near-perfect phylogenetic characters; they have recently been used with notable success to resolve some phylogenetic conundrums, but they do have certain limitations that restrict their use as 'perfect' characters for molecular systematics.
متن کاملEvolutionary history of 7SL RNA-derived SINEs in Supraprimates.
The evolutionary relationships of 7SL RNA-derived SINEs such as the primate Alu or the rodent B1 elements have hitherto been obscure. We established an unambiguous phylogenetic tree for Supraprimates, and derived intraordinal relationships of the 7SL RNA-derived SINEs. As well as new elements in Tupaia and primates, we also found that the purported ancestral fossil Alu monomer was restricted to...
متن کاملSINEs of the perfect character.
In their quest to reconstruct the tree of life, evolutionary biologists are constantly looking for new sources of data. Morphological data have been applied to the phylogeny problem since the 1800s, and morphology continues to be the only source of available data on relationships for the vast majority of species on Earth, past and present. However, since the 1960s, molecular data have contribut...
متن کاملSINEs of a nearly perfect character.
Mobile elements have been recognized as powerful tools for phylogenetic and population-level analyses. However, issues regarding potential sources of homoplasy and other misleading events have been raised. We have collected available data for all phylogenetic and population level studies of primates utilizing Alu insertion data and examined them for potentially homoplasious and other misleading...
