The Holostei were evolved from the Palaeoniscidae before the beginning of the Triassic, Acentrophorns , the earliest member, appearing in the upper Permian. About the close of the Palaeozoic era the Palaeoniscidae gave rise to several independent families which become modified to a greater or ...
Fish excrete carbonate at high rates (i.e., at least up to 105 g m−2yr−1on coral reefs)28. The global significance of this process lies in the typically high Mg/Ca ratios and low degrees of crystallinity in the excreted carbonates compared with most other biogenic marine carbona...
Newly formed allopolyploid genomes may experience instability, as the previously separate genomes of each diploid progenitor species, known as subgenomes, have evolved independently and now coexist in a single nucleus18,19. The disruption in stoichiometry of highly dosage-sensitive components of ...
500 bp) using a combination of the long PCR technique (Cheng et al.1994) and a number of fish-versatile primers (Miya and Nishida1999). During this period (1999–2014), our research group has assembled nucleotide sequences for ≈

It is suggested that recent lanternfish complexes evolved from early Tertiary faunas during the marked climatic and oceanographic fluctuations of the Pliocene and Pleistocene eras.doi:10.1029/AR035Richard Frank McGinnisMcGinnis, R.F., 1982.

and that they acquired species-specific paralogs after speciation. The tetrapodcymis positioned as a tetrapod-specific paralog. Thepgaparalogs of the coelacanth, a lobe-finned fish, formed a single branch, suggesting thatpgaparalogs evolved independently in lobe-finned fish (Fig.5b, clear highlight...
Many species have evolved or currently coexist in sympatry due to differential adaptation in a heterogeneous environment. However, anthropogenic habitat modifications can either disrupt reproductive barriers or obscure environmental conditions which underlie fitness gradients. In this study, we evaluated the ...

The Clarias catfishes evolved independently on all landmasses from a common marine ancestor that has since either become extinct or remains undiscovered. A similar diversification pattern was observed in other fish species across continents [74,75,76]. Such species diversification and colonization are ...
