The Origin of Vertebrate Gills [PDF]
Current Biology, 2017 Pharyngeal gills are a fundamental feature of the vertebrate body plan [1]. However, the evolutionary history of vertebrate gills has been the subject of a long-standing controversy [2-8]. It is thought that gills evolved independently in cyclostomes (jawless vertebrates-lampreys and hagfish) and gnathostomes (jawed vertebrates-cartilaginous and bony ...

The spotted gar genome illuminates vertebrate evolution and facilitates human-to-teleost comparisons
Nature Genetics, 2016 To connect human biology to fish biomedical models, we sequenced the genome of spotted gar (Lepisosteus oculatus), whose lineage diverged from teleosts before teleost genome duplication (TGD).

Proceedings of the National Academy of Sciences, 2000 Vertebrate innovations include neural crest cells and their derivatives, neurogenic placodes, an elaborate segmented brain, endoskeleton, and an increase in the number of genes in the genome. Comparative molecular and developmental data give new insights into the evolutionary origins of these characteristics and the complexity of the vertebrate ...

RNA interference: more than a research tool in the vertebrates' adaptive immunity
Retrovirology, 2005 In recent years, RNA silencing, usage of small double stranded RNAs of ~21 – 25 base pairs to regulate gene expression, has emerged as a powerful research tool to dissect the role of unknown host cell factors in this 'post-genomic' era.

Biochemical mechanisms of vertebrate hedgehog signaling
Development, 2019 Signaling pathways that mediate cell-cell communication are essential for collective cell behaviors in multicellular systems. The hedgehog (HH) pathway, first discovered and elucidated in Drosophila, is one of these iconic signaling systems that plays ...

The smallest known Devonian tetrapod shows unexpectedly derived features [PDF]
Royal Society Open Science, 2020 A new genus and species of Devonian tetrapod, Brittagnathus minutus gen. et sp. nov., is described from a single complete right lower jaw ramus recovered from the Acanthostega mass-death deposit in the upper part of the Britta Dal Formation (upper ...
