A vertebral column. (a back bone)
All chordates have a notochord (or backbone in vertebrates), a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail at some point in their development. These characteristics are present at least during some stage of their life cycle.
True. All chordates have a dorsal tubular nerve cord, which is a defining characteristic of this phylum.
No, pharyngeal slits do not disappear before birth in all chordates. In some chordates, such as fish, these slits persist throughout their life and play a role in respiration and feeding. In other chordates, such as mammals, the pharyngeal slits do not persist through adulthood but are present during embryonic development.
humans are vertebrates as hey have the vertebral column(to be more specific the notochord). u can feel your vertebral column by placing your hand on your back.the bony structure that seems to divide your back into two equal halves is nothing but your vertebral column.
Not necessarily. While some chordates, like humans and other mammals, have relatively large brains compared to their body size, not all chordates have large brains. Chordates range in complexity from simple organisms like tunicates to more advanced vertebrates like birds and primates.
a ancestral trait is a distinguishing feature that has been past on from a ancestor
An ancestral trait is a trait that is shared by a group of organisms and their common ancestor. It is a characteristic that has been inherited from a common ancestor and has been passed down through generations without change.
In evolutionary biology, a derived trait is a new characteristic that has evolved in a species, while an ancestral trait is a trait that has been inherited from a common ancestor. Derived traits are unique to a particular species and can help distinguish it from others, while ancestral traits are shared among related species.
A trait shared with a common ancestor is called an inherited or ancestral trait.
all vertebrates are chordates because vertebrates are the sub- group of phylum chordates and also it follow one of the important feature of the chordates i.e. presence of notochord whereas all chordates are not vertebrates because some chordates are cephalochordates, urochordates.
All chordates have a notochord (or backbone in vertebrates), a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail at some point in their development. These characteristics are present at least during some stage of their life cycle.
It has a nerve chord running down its back, the defining trait of all chordates.
One phylum trait of a mouse is being classified under the phylum Chordata, which indicates that mice possess a notochord at some stage in their development. This phylum trait is a defining characteristic of all chordates, including mammals like mice.
Derived traits are traits that appeared in the most recent common ancestor of the group and was passed on to it's decedents. Ancestral traits are inherited directly from the ancestor
I'm fourth generation Australian, a volatile mixture of Italian, Irish and Scots ancestry.
There isn't a "popular name" for them. The most familiar chordates are the vertebrates, but not all chordates are vertebrates (tunicates, for example, are chordates).
All chordates are deuterostomes, meaning that in all chordates, the anus develops first during embryological development. All chordates are bilaterally symmetric. Most chordates have a complete digestive tract, and a body cavity. Note: not all chordates have these features, but it is believed that their absence in some chordates is secondary. All chordates are of course animals and eukaryotes.
