According to the Theory of Evolution, all organisms have a shared ancestry.
Also, amphibian is a term that can be used to indicate a particular property (ie. coldblooded organism living both on land and in water) that may belong to groups of organisms stemming independently from divergent clades. Used in this sense amphibians are a paraphyletic group. The term amphibian can also be used to indicate a member of the clade Amphibia, a monophyletic grouping within cladistics.
The most recent ancestor common to Amphibia and Reptilia (which would include Mammalia, under the monophyletic usage) would have belonged to the clade of Tetrapoda. This means that both Amphibia and Reptilia (including Mammalia) are Tetrapoda.

What are the key differences between derived characteristics and ancestral characteristics in evolutionary biology?
Derived characteristics, also known as apomorphies, are traits that have evolved in a particular group of organisms and are not present in their ancestors. Ancestral characteristics, or plesiomorphies, are traits that are shared with the ancestors of a group of organisms. The key difference is that derived characteristics are unique to a specific group and have evolved over time, while ancestral characteristics are traits that have been inherited from common ancestors.
What is a Evolved from lobe-fined fish?
Evolved from lobe-finned fish, tetrapods are a group of vertebrates that includes amphibians, reptiles, birds, and mammals. One of the key characteristics that distinguish them is having limbs with digits, which evolved from the lobed fins of their fish ancestors. This transition from water to land was a crucial step in the evolutionary history of vertebrates.
What family is the lizard from?
lizards are a group of reptiles that evolved from amphibians.
What came before the fish amphibians reptiles and dinosaurs?
Fish, reptiles, and amphibians, originated in that order during the Paleozoic era.
Did amphibians and mammals descend from reptiles?
Reptiles evolved from a group of reptiliomorph amphibians in the Carboniferous period. Mammals evolved from a groupof synapsidreptiles in the Jurassic period.
What group evolved from the amphibians with the development of the amniotic egg?
reptiles
Which group of vertebrates evolved after fish?
Amphibians, then reptiles, birds, and finally mammals!
Which group of fish do scientists believe amphibians evolved from?
Lobe-finned fishes are though to have given rise to amphibians. This is due to the body plan and body symmetry of the fish, which is very similar to that of an amphibian.
What statement about ancestral traits is true?
Ancestral traits are characteristics that are inherited from common ancestors of a group of organisms. These traits can provide valuable insights into the evolutionary history and relationships among different species. Studying ancestral traits can help scientists understand how traits have evolved over time and how organisms are related to each other.
What group of animals is thought to have left the ocean to become the first amphibians?
Devonian, lobe-finned fish had evolved into air-breathing amphibians with strong legs, yet retained a fish-like head and tail.
Why do snakes have hip bones?
Because their ancestors had legs. Snakes most likely evolved from a group of lizards related to modern monitor lizards.
Did mammals evolve from a group of reptiles called raptors?
No. Mammals evolved from a group of reptiles called cynodonts. "Raptor" is an informal term for a group of dinosaurs call dromaeosaurids, which were closely related to the ancestors of birds.
