What is a chordate family tree?
A chordate family tree is a graphical representation of the evolutionary relationships between the various animal species that have backbones.
How are animals with backbones different from those without?
They are different because they have one. The most important evolutionary advantages of this are :- The notochord is now inside the backbone - the spinal cord. The notochord gave greater functionality to the nervous system, but it was very vulnerable to trauma whether accidentally or in combat. Inside the backbone it is well protected. The spine gives great flexibility to the organism; physical flexibility of course, but also making the evolution of complex shapes easier.
Why are vertebrates classified into different groups?
vertbrates are classified into different groups cause they have backbone and spine of structures for each group

How can a notochord differ from a proper backbone?
A notochord is a flexible rod-like structure found in some chordates, providing support, while a proper backbone is a more complex structure made of vertebrae. Backbones have more specialized functions, such as protecting the spinal cord and allowing for more precise movement. Notochords are often found in embryonic stages and may be replaced by a backbone during development.
What is a different name for the backbone?
