This suggests that alterations in the interpretation of the Hox code may have participated to the evolution of this region in tetrapods, along with potential modifications of the HOX proteins themselves. With its reduced vertebral number, this mouse stock violates a previously described developmental ...
It has been postulated frequently that the fundamental organization of the basal ganglia (BG) in vertebrates arose with the appearance of amniotes during evolution. An alternative hypothesis, however, is that such a condition was already present in early anamniotic tetrapods and, therefore, characteri...
Pelvic fins evolved in placoderms and crown-group gnathostomes [37], and from the latter, sarcopterygians evolved 423 million years ago (Ludlow Epoch of the Silurian) [38] (Fig.1). Tetrapodomorphs evolved as a clade within the Sarcopterygia (Fig.1), specifically sharing the last common ...

A survey of sex chromosomes in tetrapods has revealed instances of sex chromosome homology between distantly related groups, and posed the question of whether this homology represents identity by descent or the independent evolution of sex chromosomes from the same autosome (Graves and Peichel, 2010)...
Urea cycle in tetrapods, fish and invertebrates. The first three enzymes of the urea cycle are localized in the mitochondria; the remaining three enzymes are cytoplasmic. Mammals and amphibians (tetrapods) have CPSI, which catalyzes the formation of CP from ammonia, bicarbonate and ATP. NAG is...
The traditional notion of a gap between fishes and amphibians has been closed by a wealth of fish-like fossil tetrapods, many discovered since the mid 1980s. This review summarizes these discoveries and explores their significance relative to changing ideas about early tetrapod phylogeny, biogeography...
The discovery of differentially organized sex chromosome systems suggests that heteromorphic sex chromosomes evolved from a pair of homologous chromosomes. Whereas karyotypes are highly conserved in alethinophidian snakes, the degeneration status of the
Thus, KRAB-zinc finger genes presumably coevolved with or occurred shortly after the appearance of tetrapodes and underwent a huge expansion during mammalian evolution. It was hypothesized that KRAB-like sequences in the histone methyltransferase Meisetz date the origin of this domain back to the ...
