Lungfish - Wikipedia
Through convergent evolution, lungfishes have evolved internal nostrils similar to the tetrapods' choana, [4] and a brain with certain similarities to Lissamphibian brain (except for the Queensland lungfish, which branched off in its own direction about 277 million years ago and has a brain resembling that of the Latimeria).

Lungfish evolution and development - ScienceDirect
2006年9月15日 · Despite intensive research and new fossil discoveries over the last century, there still remains speculation over the phylogenetic relationship between lungfish and the fish group most directly ancestral to the tetrapods (Janvier, 1998).
Lungfish evolution and development - PubMed
2006年9月15日 · It is generally agreed that their ancestors were lobe-finned fish. What is not agreed is how close either of the extant groups of lobe-finned fish, lungfish or coelacanths, is to the actual ancestor of the tetrapods. The soft anatomy of living lungfish shares many similarities with that of living amphibians.
Evolutionary history of lungfishes with a new phylogeny of post ...
2017年4月1日 · Here, we propose a phylogenetic analysis of post-Devonian lungfishes, including some Carboniferous and Permian forms, on the basis of a new set of morphological characters. These characters can be assessed on most of the specimens, and discriminate mostly the post-Palaeozoic genera.
The Lungfish Transcriptome: A Glimpse into Molecular Evolution …
2016年2月24日 · The transition from water to land required massive changes in physiology and body plan, some of which are already obvious in the amphibious lungfish. A major change was the evolution of paired fins to the tetrapod limbs, while the …
LSU Researcher Decodes Lungfish Genome, Revealing …
2024年8月14日 · By comparing the genomes of different lungfish species, the team identified a gene regulatory module crucial for digit development in humans that also plays a vital role in shaping the fin structures of lungfish. This discovery strengthens the hypothesis that human limbs evolved from fish fins.
