The group can be made monophyletic by including the birds (Aves). b. they have a common ancestry. 5. Abstract. Cladistic Because the term is defined negatively, and excludes the tetrapods (i.e., the amphibians, reptiles, birds and mammals) which descend from within the same ancestry, it is paraphyletic.
A good example of a paraphyletic clade is the reptiles. In this case, reptiles form a monophyletic group. D. monophyletic group.
For example, the taxonomic group `reptiles' used in evolutionary systematics is paraphyletic because it excludes birds and mammals, which share the same common Just how closely related are trilobites, chelicerates, myriapods, hexapods, and crustaceans? It asks why fish are a paraphyletic group. The members included are those that have changed little from the ancestral state; those that

As is made clear by the picture, reptiles include a group of animals which is paraphyletic. Reptiles, mammals and birds all share a common ancestor. This is a paraphyletic group because it excludes the mammals (Mammalia) and Originally, reptiles and birds were classified into separate equal-rank taxa. Why are fish considered paraphyletic? Play Sound. A paraphyletic group contains some, but not all, of the descendants from a common ancestor. (1988a) phylogeny was the principal reference for amniote interrelationships and taxonomy until Laurin and Reisz (1995) identified turtles as the sister In the 18th century, the reptiles were, from the outset of classification, grouped with the amphibians. C. paraphyletic group.
The answer is because they don't include tetrapods, but I don't understand why tetrapods have anything to do with this.
Why do we consider "Reptiles" to be a paraphyletic group. I want to know about the current scientific consensus in regards to Reptiles as being an Monophyletic grouping or class. In the traditional Linnaean classification system, reptiles represent a paraphyletic grouping. Bring your group or organization to explore and learn about amazing and incredible animal species that our world has to offer. 2- Mammals and birds are not reptiles and
Paraphyletic group. Reptiles are a paraphyletic group: in terms of appearance a crocodile has more in common with lizards than birds and both crocodiles and lizards are classed as reptiles. However, crocodiles share a more common recent ancestor with birds than with lizards. but excludes the extinct 'mammal-like reptiles' as they used to be known, which are more closely related to mammals. Living reptiles comprise turtles, crocodilians, squamates (lizards and snakes) and rhynchocephalians ().As of March 2022, the Reptile Database lists about the class includes about 11,700 species. A taxon (pl.
The perhaps most compelling example for a paraphyletic group are the Reptilia (turtles, tuataras, lizards and snakes, crocodiles plus dinosaur-like reptiles), the lineage which also gave rise to
A paraphyletic group, on the other hand, is a given ancestor, and all of its descendants "except a few we want to leave out because reasons". Originally, birds were in their own class. M. M9Powell.
E. none of the above is correct. Reptiles are a group of four-legged vertebrates (also known as tetrapods) that diverged from ancestral amphibians approximately 340 million years ago. Otherwise, reptiles are paraphyletic because the group does not include all of the descendants of the common ancestor. Why are reptiles as traditionally defined a paraphyletic group? How has cladistic taxonomy revised Reptilia to make it monophyletic? However, crocodiles Comparison: monophyly = yellow, polyphyly = red, paraphyly = aqua. Ans:- Reptiles are traditionally defined as paraphyletic group because all descendants of their common ancestors are not included in one group (excludes View the full answer 2. Why did reptiles become a paraphyletic group and what was done to correct this? In the 13th century the category of reptile was recognized in Europe as consisting of a miscellany of egg-laying creatures, including "snakes, various fantastic monsters, lizards, assorted amphibians, and worms", as recorded by Vincent of Beauvais in his Mirror of Nature. None of the choices is correct.

Can you explain why the yellow polygon also represents a paraphyletic group? Solutions for Chapter 26 Problem 4RQ: Why are reptiles, as traditionally defined, a paraphyletic group?
There is two answers: 1- Mammals and birds are reptiles (as we are osteichthies). Fish.
Come see why generations of families remember us when they visit Brainerd, MN and make a few lasting memories of your own.
Reptiles are paraphyletic because birds (and mammals, if you consider stem synapsids to be reptiles, aka mammal-like reptiles) are not considered reptiles, but descend from lineages that In I agree with you, answer is B. Reptilia is a clade (clade = monophyletic group) that encompasses all species that we traditionally classify as reptiles + all birds.
How has cladistic taxonomy revised Reptilia to make it monophyletic?
The Gauthier et al. A: To answer this Eurysternum is considered a stem group turtle of the extinct marine taxon Thalassochelydia, which is close to the crown group of turtles and tortoises. I photographed this wonderful fossil in 2015 in Mrnsheim on the occasion of the presentation of a two-volume monograph on the fossils of the Solnhofen Limestone ( Arratia et al. Loosely although most phylogenetic taxonomists would use that term to included paraphyletic taxa.
However, the reptiles form a d. 18. Is it correct to say that reptiles are a paraphyletic group? The descendants of the fish common ancestor also include all tetrapods (four-legged animals), like amphibians, reptiles, mammals, and birds. Monophyletic groups contain all the branches below a given ancestor; nothing is said about the phenetic evolution of species within each branch. Reptiles are a paraphyletic group: in terms of appearance a crocodile has more in common with lizards than birds and both crocodiles and lizards are classed as reptiles. Classification of reptiles Reptiles are a paraphyletic group. The reptiles as defined above would be paraphyletic, since they exclude both birds and mammals, although these also developed from the original reptile.
They sort of are because they are basically a grab-bag of those air-breathing vertebrates that dont fit as amphibians or A fossilized trilobite. Reptiles, as most commonly defined, are the animals in the class Reptilia (/ r p t l i /), a paraphyletic grouping comprising all sauropsid amniotes except Aves ().
The group can be made monophyletic by including the birds (Aves). The traditional term pisces (also ichthyes) is considered a typological, but not a Linnaeus, worki c. they do not include all Having the group description include an except X is what makes a group paraphyletic. Reptiles are paraphyletic because birds (and mammals, if you consider stem synapsids to be reptiles, aka mammal-like reptiles) are not considered reptiles, but descend from lineages that are considered reptiles. b.

The reptiles certainly do represent a paraphyletic group. Reptilia is paraphyletic with respect to Mammalia (the mammals) and Aves (the birds). [While mammals, birds, and reptiles have a common amniotic ancestor, both mammals and birds are, in and of themselves, monophyletic.] Hence, our traditional definition of reptile makes up for a paraphyletic group as birds aren't included.
Reptiles are a paraphyletic group: in terms of appearance a crocodile has more in common with lizards than birds and both crocodiles and lizards are classed as reptiles.
Protists are a paraphyletic group because animals, fungi, and plants are the crown groups evolved from different lineages of the protists. Best Answer.
From the classical standpoint, reptiles Ad Honorem. Until recently, naturalists considered the possibility that these families were "paraphyletic" (that is, that they evolved separately from animals that lived hundreds of millions of years ago, rather than having a last common ancestor).
