First, it allows for the development of a brain. The brain acts as a control center to organize and control sensory information. Over time, animals can evolve complex neural systems and develop higher intelligence. The second advantage of cephalization is that sense organs can cluster at the front of the body.

What is the evolutionary significance of cephalization?
They evolved cephalization. This is the concentration of nerve tissue at one end of the body, forming a head region. This is highly adaptive. It allows central control of the entire organism. Cephalization was first step in the evolution of a brain.
What is cephalization in animal evolution quizlet?
-Cephalization: nervous tissue, over many generations, becomes concentrated toward one end of an organism. This process eventually produces a head region with sensory organs.
How is Cephalisation advantageous to animals in finding food?
Since the head forms the anterior part of the body, cephalization helps the animal to sense the surrounding with the help of sense organs. ... Formation of head also leads to formation of apperdages such as antennae which will be of use in finding food.
What is cephalization and its uses?
Cephalization is the process of central nervous system in which the hardening or the deposition of calcium takes place , also nervous tissue becomes concentrated at one end of the organism over many generations. This process ultimately produces the head regions with the sensory organs.
What are the advantages of Cephalisation?
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.
Why was the evolution of bilateral symmetry an important step in animal evolution?
The advantages of bilateral symmetry include the formation of a head and tail region, where the head region can house a detailed nervous system, and more directional movement to include the ability to move straight forward.
Why was the evolution of Cephalization correlated with the evolution of bilateral symmetry?
Cephalization is thought to be an evolutionary adaptation resulting from the tendency of bilaterally symmetrical animals to move forward, so that information about newly encountered parts of the environment impinges first on the front of the animal.
What is the significance of the evolution of Hox gene clusters during vertebrate evolution?
Evolution of vertebrate Hox clusters and their functional specificities. In chordates, Hox genes are essential for the patterning of the neural tube and somites. In vertebrates, duplication of the ancestral Hox cluster led to the emergence of proximal appendages and nephrogenic structures.
What animal phylum gave rise to the animal kingdom?
Terms in this set (12) The animal phylum most like the protists that gave rise to the animal kingdom is ___. Porifera. (Evidence that supports this includes the lack of true tissue in sponges and the close similarity between choanocytes and choanoflagellates.)
What does it mean to call something Cephalized?
The definition of cephalization means the trend in evolution for the nervous system and the sensory organs to be positioned near the human or animal head. An example of cephalization is the tendency for an animal's ears to be on its head. noun.
What do you mean by Cephalisation?
cephalization, the differentiation of the anterior (front) end of an organism into a definite head. ... Some groups of organisms show full cephalization, but because their bodies are not divided into distinct trunks and heads, they cannot be said to possess a distinct anatomical head.
What is radial symmetry in zoology?
Radial symmetry is the arrangement of body parts around a central axis, like rays on a sun or pieces in a pie. Radially symmetrical animals have top and bottom surfaces, but no left and right sides, or front and back. ... Radial symmetry: Some organisms, like sea anemones (phylum Cnidaria), have radial symmetry.
What is significant about cephalization quizlet?
What is significant about cephalization? It allows animals to be triploblastic. It is the basis for radial symmetry. The division of body parts allows repetition of important structures.
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.
Are jellyfish Cephalized?
So many organisms exhibit cephalization that describing noncephalized animals may be the easiest way to give an idea of just how many animals are cephalized. ... These organisms include Cnidarians, such as coral, jellyfish, sea anemones and simple mollusks like scallops. Echinoderms, or sea stars, also lack cephalization.
