Why is cephalization an advantage?
Advantages of cephalization are development of a complex neural system and intelligence, clustering of senses to help an animal rapidly sense food and threats, and superior analysis of food sources. Radially symmetrical organisms lack cephalization.
What is the advantage of cephalization in arthropods?
Arthropods. In arthropods, cephalization progressed with increasing incorporation of trunk segments into the head region. This was advantageous because it allowed for the evolution of more effective mouth-parts for capturing and processing food.
