Cambrian Chordates and Vetulicolians
Geosciences (Switzerland), 2019 Deuterostomes make a sudden appearance in the fossil record during the early Cambrian. Two bilaterian groups, the chordates and the vetulicolians, are of particular interest for understanding early deuterostome evolution, and the main objective of this ...

The evolution of dopamine systems in chordates [PDF]
Frontiers in Neuroanatomy, 2011 Dopamine (DA) neurotransmission in the central nervous system (CNS) is found throughout chordates, and its emergence predates the divergence of chordates.

The Enigmatic Reissner’s Fiber and the Origin of Chordates [PDF]
Frontiers in Neuroanatomy, 2021 Reissner’s fiber (RF) is a secreted filament that floats in the neural canal of chordates. Since its discovery in 1860, there has been no agreement on its primary function, and its strong conservation across chordate species has remained a mystery for ...

Frontiers in Cell and Developmental Biology, 2021 Species retaining ancestral features, such as species called living fossils, are often regarded as less derived than their sister groups, but such discussions are usually based on qualitative enumeration of conserved traits. This approach creates a major

Characterizing the evolution and potential function of eleven horizontally transferred genes in amphioxus [PDF]
Communications BiologyHorizontal gene transfer (HGT) is the important driver for biological evolution. To date, most of the studies on HGT have focused on prokaryotes, and the HGTs involving eukaryotes are less investigated, especially for HGTs occurring in chordates. In this

Connexins evolved after early chordates lost innexin diversity
eLife, 2022 Gap junction channels are formed by two unrelated protein families. Non-chordates use the primordial innexins, while chordates use connexins that superseded the gap junction function of innexins.

Threats to Neglected Biodiversity: Conservation Success Requires More Than Charisma
Frontiers in Conservation Science, 2022 Our planet is home to an incredible array of species; however, relatively few studies have compared how anthropogenic threats impact taxonomic groups over time.

The origin and evolution of vertebrate neural crest cells [PDF]
Open Biology, 2020 The neural crest is a vertebrate-specific migratory stem cell population that generates a remarkably diverse set of cell types and structures. Because many of the morphological, physiological and behavioural novelties of vertebrates are derived from ...

Frontiers in Cell and Developmental Biology, 2020 The evolution of the vertebrate eye remains so far unresolved. Amphioxus frontal eye pigment cells and photoreceptors were proposed to be homologous to vertebrate photoreceptors and retinal pigmented epithelium, based on ultrastructural morphology and ...
