Small RNA Sequencing Study Offers Peek into Vertebrate Evolution

from GenomeWeb By a GenomeWeb staff reporter

NEW YORK (GenomeWeb News) – A new small RNA sequencing study is providing insights into how some jawless vertebrate animals called the agnathans are related to one another and to jawed vertebrates, known as gnathostomes.

A team of researchers from the US, UK, and France used high-throughput sequencing to look at the small RNA repertoire in hagfish and lamprey specimens, comparing these patterns to those found in jawed vertebrates. The research, scheduled to appear online this week in the Proceedings of the National Academy of Sciences, suggests that the present day jawless vertebrates, known as cyclostomes because of their round mouths, may belong to a single evolutionary lineage rather than arising from parallel lineages.
