Developmental constraints on vertebrate genome evolution [PDF]
PLoS Genetics 4 (2008) e1000311, 2012 Constraints in embryonic development are thought to bias the direction of evolution by making some changes less likely, and others more likely, depending on their consequences on ontogeny. Here, we characterize the constraints acting on genome evolution in vertebrates.

Steroid Receptors and Vertebrate Evolution [PDF]
arXiv, 2019 Considering that life on earth evolved about 3.7 billion years ago, vertebrates are young, appearing in the fossil record during the Cambrian explosion about 542 to 515 million years ago. Results from sequence analyses of genomes from bacteria, yeast, plants, invertebrates and vertebrates indicate that receptors for adrenal steroids (aldosterone ...

Insights from Amphioxus into the Evolution of Vertebrate Cartilage [PDF]
, 2007 Central to the story of vertebrate evolution is the origin of the vertebrate head, a problem difficult to approach using paleontology and comparative morphology due to a lack of unambiguous intermediate forms. Embryologically, much of the vertebrate head

eLife, 2020 Phylogenetic analysis of morphological data proceeds from a fixed set of primary homology statements, the character-by-taxon matrix. However, there are cases where multiple conflicting homology statements can be justified from comparative anatomy.

Diversity, 2021 This paper reviews current research on the microbial life that surrounds vertebrate embryos. Several clades are believed to develop inside sterile—or near-sterile—embryonic microhabitats, while others thrive within a veritable zoo of microbial life.

Evolution of thymopoietic microenvironments [PDF]
Open Biology, 2021 In vertebrates, the development of lymphocytes from undifferentiated haematopoietic precursors takes place in so-called primary lymphoid organs, such as the thymus.

The whale shark genome reveals patterns of vertebrate gene family evolution
eLife, 2021 Chondrichthyes (cartilaginous fishes) are fundamental for understanding vertebrate evolution, yet their genomes are understudied. We report long-read sequencing of the whale shark genome to generate the best gapless chondrichthyan genome assembly yet ...

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 ...

Evolution of parathyroid hormone receptor family and their ligands in vertebrate
Frontiers in Endocrinology, 2015 The presence of the parathyroid hormones in vertebrates, including PTH, PTH-related peptide (PTHrP) and tuberoinfundibular peptide of 39 residues (TIP39), has been proposed to be the result of two rounds of whole genome duplication in the beginning of ...

High‐altitude adaptation in vertebrates as revealed by mitochondrial genome analyses
Ecology and Evolution, 2021 The high‐altitude environment may drive vertebrate evolution in a certain way, and vertebrates living in different altitude environments might have different energy requirements.
