LOCOMOTORY BEHAVIOUR OF EARLY TETRAPODS FROM BLUE BEACH, NOVA SCOTIA, REVEALED BY NOVEL MICROANATOMICAL ANALYSIS

Locomotory behaviour of early tetrapods from Blue Beach, Nova Scotia, revealed by novel microanatomical analysis

Evidence for terrestriality in early tetrapods is fundamentally contradictory.Fossil trackways attributed to early terrestrial tetrapods long predate the first body fossils from the Late Devonian.However, the Devonian body fossils demonstrate an obligatorily aquatic lifestyle.Complicating our understanding of the transition from water to land is a

The dynamic intein landscape of eukaryotes

Abstract Background Inteins are mobile, self-splicing sequences that interrupt proteins and occur across all three domains of life.Scrutiny of the intein landscape in prokaryotes led to the hypothesis that some inteins are functionally important.Our focus shifts to eukaryotic inteins to assess their diversity, distribution, and dissemination, with
