Morphometric analysis of lungfish endocasts elucidates early dipnoan palaeoneurological evolution

eLife, 2022
The lobe-finned fish, lungfish (Dipnoi, Sarcoptergii), have persisted for ~400 million years from the Devonian Period to present day. The evolution of their dermal skull and dentition is relatively well understood, but this is not the case for the ...

Tell Us a Story Granddad: Age and Origin of an Iconic Australian Lungfish

Frontiers in Environmental Science, 2022
The modern discovery of the Australian lungfish (Neoceratodus forsteri) by European settlers in 1870 was considered one of the most important events in natural history by leading international scientists and naturalists of that time.

Shifts in type 2 vomeronasal receptor expression during postnatal development in the lungfish olfactory organ. [PDF]

J Anat
Lungfish possess a lamellar OE and a primitive VNO called as a recess epithelium (RecE). Among the lungfish V2Rs expressed in both the lamellar OE and the RecE in small individuals, some became restricted to the RecE in large individuals. These results suggest functional separation between the lamellar OE and the RecE is still incomplete in juveniles ...

A Metapopulation Model to Assess Water Management Impacts on the Threatened Australian Lungfish, Neoceratodus forsteri

Fishes
The Australian lungfish, Neoceratodus forsteri, is one of the world’s oldest vertebrate lineages, with a slow life-history and threatened status, requiring immediate conservation efforts.

Bony fish genomes: Status and gaps. [PDF]

J Fish Biol
Abstract Bony fish constitute an exceptionally species‐rich group of aquatic vertebrates, comprising more than 95% of all living fish. The adaptive processes on the diversity of environments they inhabit make them a highly diverse group from taxonomic, morphological and evolutionary standpoints.

Phylogenomics Based on Transcriptome Data Provides Evidence for the Internal Phylogenetic Relationships and Potential Terrestrial Evolutionary Genes of Lungfish

Frontiers in Marine Science, 2021
The evolutionary relationships of lungfish can provide crucial information on the transition from Sarcopterygii to tetrapods. Phylogenomics is necessary to explore accurate internal phylogenetic relationships among all lungfish species. In the context of

Two Paralogues as They Like It: Conserved and Divergent Evolution of Vertebrate Gcm Genes. [PDF]

Evol Dev
Comparative overview of Gcm1 and Gcm2 paralogues across vertebrates. Gcm2 is conserved in pharyngeal‐derived organs across gnathostomes, whereas Gcm1 shows lineage‐specific diversification from an ancestral pharyngeal context, including secondary loss in teleosts, distinct expression in bichir gills and skin, and broader expression in mammals ...

Living animals for comparison in studies of Mesozoic fossils. [PDF]

Research & Knowledge, 2017
Lungfish are timeless, starting in the Devonian and still found today. Unfortunately this does not mean that biologists and palaeontologists agree about the functional anatomies of dipnoans.

Type 1 vomeronasal receptor expression in juvenile and adult lungfish olfactory organ

Zoological Letters, 2023
Lungfish are the most closely related fish to tetrapods. The olfactory organ of lungfish contains lamellae and abundant recesses at the base of lamellae.

“Living fossils” and the mosaic evolution of characters

Frontiers in Ecology and Evolution, 2023
The modern discussion of living fossils turns mostly on the persistence of archaic, or ancestral, traits in extant organisms. Prime examples mentioned by Darwin already—who also coined the term “living fossil”—include the platypus and the extant ...
