Discriminating signal from noise in the fossil record of early vertebrates reveals cryptic evolutionary history [PDF]
, 2014 The fossil record of early vertebrates has been influential in elucidating the evolutionary assembly of the gnathostome bodyplan. Understanding of the timing and tempo of vertebrate innovations remains, however, mired in a literal reading of the fossil ...

Re‐make, re‐model: evolution and development of vertebrate cranial lateral lines
Biological Reviews, Volume 100, Issue 6, Page 2237-2256, December 2025.ABSTRACT Lateral lines are placodally derived mechanosensory systems on the heads and trunks of many aquatic vertebrates. There is evidence of lateral lines in the earliest known vertebrate fossils, and they exist in organisms with widely different craniofacial morphologies – including the presence or absence of jaws, external or internal nostrils, and

The Interrelationship of Estrogen Receptor and GnRH in a Basal Vertebrate, the Sea Lamprey
Frontiers in Endocrinology, 2011 The hypothalamic-pituitary system is considered to be a vertebrate innovation and seminal event that emerged prior to or during the differentiation of the ancestral agnathans.

Histology and affinity of anaspids, and the early evolution of the vertebrate dermal skeleton [PDF]
, 2016 The assembly of the gnathostome bodyplan constitutes a formative episode in vertebrate evolutionary history, an interval in which the mineralized skeleton and its canonical suite of cell and tissue types originated. Fossil jawless fishes, assigned to the

China shares fossil treasures with the world
The Anatomical Record, Volume 308, Issue 10, Page 2806-2812, October 2025.Abstract China has been a rich source of fossils for nearly a century, beginning with the discovery of so‐called Peking man (Sinanthropus pekinensis), known today as Homo erectus pekinensis in the mid 1920s. The first Chinese dinosaurs were described in 1929, the sauropod Helopus (now Euhelopus) and the ornithopod Tanius, described by the Swedish ...

BMC Ecology and Evolution, 2021 Background Four ohnologous genes (sox1, sox2, sox3, and sox15) were generated by two rounds of whole-genome duplication in a vertebrate ancestor. In eutherian mammals, Sox1, Sox2, and Sox3 participate in central nervous system (CNS) development.

Oligodendrogenesis in Evolution, Development and Adulthood
Glia, Volume 73, Issue 9, Page 1770-1783, September 2025.Main Points Oligodendrocytes and myelin took shape in jawed vertebrates During development, OPCs are originated from NSCs and then undergo differentiation into mature oligodendrocytes that supply myelin. OPCs persist in the adult CNS and continue to produce oligodendrocytes and myelin.

Serotonin signaling contribution to an evolutionary success: the jaw joint of vertebrates
The European Zoological Journal, 2017 Serotonin (5-HT) is an ancient molecule that appeared very early during evolution, and it is present in different phyla. The 5-HT signaling system includes several G-coupled receptors and it is widely conserved in vertebrates.
