The basal clade of amphibians is represented by the group known as "urodeles," or salamanders, which are believed to have diverged early in amphibian evolution. This clade includes some of the most primitive forms of amphibians, showcasing key evolutionary traits such as a dual life cycle, transitioning from aquatic larvae to terrestrial adults. Urodeles provide insights into the evolution of amphibian characteristics and adaptations. Additionally, their evolutionary history highlights the transition from water to land among vertebrates.
What else can I help you with?
What does transitional mean?
In the context of palaeontology, calling a fossil a 'transitional form' means that it's morphologically intermediate between a basal clade and a specific derived clade. Meaning that the shapes of its bones are such as would be expected from a descendant of the basal clade that is also ancestral to the derived clade.
What evolves to become the ancestor of all four limbed animals?
All four-limbed animals belong to the clade of Tetrapoda. The clade of Tetrapoda is defined as the first basal four-limbed animals and all their descendants, extant and extinct. The clade immediately superior (ancestral) to that is the clade of Teleostomi, which contains all jawed vertebrates, including the tetrapods, bony fish, and the extinct lineage of acanthodian fish.
What are characteristics that are shared by members of a clade and only by members of that clade?
Derived Characteristics.
When was Emil Clade born?
Emil Clade was born on 1916-02-26.
The taxonomy group of sampaguita?
The scientific classification of sampaguita is: Kingdom: Plantae Clade: Tracheophytes Clade: Angiosperms Clade: Eudicots Clade: Asterids Order: Gentianales Family: Rubiaceae Genus: Jasminum Species: Jasminum sambac
Did modern reptiles evolve from dinosaurs?
No, although modern reptiles and dinosaurs do share common ancestors that lived in the distant past (likely the Carboniferous epoch). Birds, however, evolved from dinosaurs in the Jurassic epoch.
What is basal eudicots?
Basal eudicots refer to a group of flowering plants that represent some of the earliest diverging lineages within the eudicot clade. This group includes families such as Ranunculaceae (buttercup family) and Nymphaeaceae (water lilies), which exhibit diverse morphological traits. Basal eudicots are characterized by features like distinct floral structures and unique leaf forms, distinguishing them from more derived eudicots. Their evolutionary significance lies in providing insights into the early diversification and characteristics of eudicot plants.
What is basal adjectives?
basal adjective is an adjective that is basal
What clade does Euglena belong too phylogenically?
Euglena belongs to the clade Euglenozoa phylogenetically. This clade includes single-celled organisms with a flagellum and is part of the Excavata supergroup in the domain Eukarya.
Who is Dr Jerome R Clade?
Dr. Jerome R. Clade is the author of the book "The Fundamentals of Animal Behavior".
What are differences and similarities between a class reptilia and a clade reptilia?
clade and class are different because one says clade and the other says class. the same thing they have in common is that they both have reptilia at the end.
What are the character states shared by the ancestor or outgroup of a clade called?
Character states shared by the ancestor or outgroup of a clade are referred to as plesiomorphies. These are ancestral traits that were present in the common ancestor of a group but are not unique to the members of the clade.
