Evolution of tetrapods - Wikipedia
网页The evolution of tetrapods began about 400 million years ago in the Devonian Period with the earliest tetrapods evolved from lobe-finned fishes. [1] Tetrapods (under the apomorphy -based definition used on this page) are categorized as animals in the biological superclass Tetrapoda , which includes all living and extinct amphibians , reptiles ...
The origin of tetrapods - Understanding Evolution
网页Tetrapods evolved from a finned organism that lived in the water. However, this ancestor was not like most of the fish we are familiar with today. Most animals we call fishes today are ray-finned fishes, the group nearest the root of this evogram.

The African coelacanth genome provides insights into tetrapod evolution
网页2013年4月17日 · Genome sequencing and phylogenomic analysis show that the lungfish, not the coelacanth, is the closest living relative of tetrapods, that coelacanth protein-coding genes are more slowly evolving...
网页Evolutionary trees of tetrapod ancestry have long since branched and filled to accommodate earlier and more thor-oughly transitional forms (Clack 2002), but the vignette of beached missing links has persisted. Unfortunately, this paleo-cliche reduces the exploration of tetrapod origins to the discovery of

Rise of the Earliest Tetrapods: An Early Devonian Origin from
网页2011年7月14日 · The results have shown that tetrapods evolved from marine environments during times of higher oxygen levels. The change in environmental conditions played a major role in their evolution. According to our analysis this evolution occurred at about 397–416 MYA during the Early Devonian unlike previously thought.
