What is the function of the arthropod exoskeleton? What is the function of the arthropod exoskeleton? The presence of an exoskeleton has given arthropods a good fossil record, because hard parts fossilize more readily than do soft tissues. It makes growth by molting possible. It provides protection and functions in locomotion. It has no well-established function. (Trilobites had an exoskeleton, and they went extinct.)

answer; /// i do believe its (heredity); good luck

phylogenetic tree is the tree of life or evolution tree. it shows the different branches of evolution. the sequence goes like tissues - coelom - backbone - endoskeleton - segmentation

a motor homunculus represents a map of brain areas dedicated to motor processing for different anatomical divisions of the body.

homunculus represents the importance of various parts of your body as seen by your brain. as a result, they take up a lot of brain space. although the cortical homunculus is a curiosity, penfield's work in mapping the brain's relationship to the body was invaluable.
