What is most closely related to chordates?
The echinoderms are most closely related to the chordates.
What makes a reptile a chordate?
All chordates possess five synapomorphies, or primary characteristics, at some point during their larval or adulthood stages that distinguish them from all other taxa. These five synapomorphies include a notochord, dorsal hollow nerve cord, endostyle or thyroid, pharyngeal slits, and a post-anal tail.
Are reptiles Chordata?
Like snakes, lizards belong to the animal kingdom, phylum Chordata (animals with backbones–also known as vertebrates). They are reptiles.
Which animal phylum is most closely related to the phylum Chordata?
Echinoderms
Echinoderms are the most closely related phylum to the phylum Chordata, which includes many complex organisms such as humans. Echinoderms are deuterostomes that exhibit pentameral radial symmetry.
Which characteristic is common to all chordates?
In chordates, four common features appear at some point during development: a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail.
Which phylum contains reptiles?
ChordateReptiles / Phylum
Which of the following are the closest living relatives of chordates?
The closest relatives of the chordates are probably the hemichordates, since these animals possess gill slits and other features not found in other animal phyla.
Which of the following is considered to be a reptile?
Reptiles are air-breathing vertebrates covered in special skin made up of scales, bony plates, or a combination of both. They include crocodiles, snakes, lizards, turtles, and tor- toises.
Which group of organisms is the closest relative to chordates?
Answer: According to cladogram, Echinoderms are the organisms which are closest relative to chordates. Explanation: It is proved that Echinoderms and chordates are from common ancestral origin.
Which of the following is a characteristic of all chordates at some point during their life cycle?
Which of the following is a characteristic of all chordates at some point during their life cycle? aid in swimming; adults are sessile and thus no longer propel themselves.
Are chordates vertebrates or invertebrates?
The most conspicuous and familiar members of Chordata are vertebrates, but this phylum also includes two groups of invertebrate chordates. All chordates are deuterostomes possessing a notochord.
What are the characteristics of chordate evolution?
-Lancelets and Chordates are invertebrates List the characteristics of Chordate Evolution 1. Most chordates are vertebrates. -Backbone and other skeletal elements are components of the endoskeleton (internal skeleton) 2. Hinged skeletal elements- “jaws” evolved, new strategies for feeding
What are Chordata and Urochordata?
Chordata also contains two clades of invertebrates: Urochordata and Cephalochordata. Members of these groups also possess the four distinctive features of chordates at some point during their development. Members of Urochordata are also known as tunicates ( [link] ).
What is the function of the pharyngeal slits in chordates?
Some invertebrate chordates use the pharyngeal slits to filter food out of the water that enters the mouth. In vertebrate fishes, the pharyngeal slits are modified into gill supports, and in jawed fishes, into jaw supports.
