What are the consequences of bilateral symmetry?

The fact that we have two eyes and ears means that we can see and hear more than most animals with radial symmetry. Bilateral symmetry also caused the formation of a head and tail area. This means that things can go in one end and come out the other, as opposed to everything having to use the same opening.

How does bilateral symmetry affect movement?

Having bilaterally symmetrical bodies (the same on both sides along an axis) permit them to propel forward in a straight line. In evolutionary history, animals that moved quickly and efficiently from point A to point B would have been more successful and selected for than those who were ineffective at locomoting.

What are some advantages of radial symmetry or bilateral symmetry?

One advantage of having radial symmetry is that the animal can get food from any direction. Larger, more complex animals all have bilateral symmetry. They have very different front and back ends. Different parts of the body are specialized to do different jobs.

What are the advantages of bilateral symmetry and Cephalization?

Better Brains Mean Smarter, Faster Bodies

A complex brain that is attached to and controls a complex body. The combination of cephalization and bilateral symmetry allowed for the development of a digestive system consisting of a mouth at one end and an anus at the other.

How does bilateral symmetry differ from radial symmetry?

The balanced distribution of the body shapes is referred to as the biological symmetry. ... The key difference between radial and bilateral symmetry is that radial symmetry generates identical body halves around the central axis whereas bilateral symmetry generates only two sides as left and right.

How do bilateral symmetry radial symmetry and asymmetry affect the feeding habits of an animal?

Their bodies are shaped irregularly like some animals including most sponges they lack any symmetry. How do bilateral symmetry radial symmetry and asymmetry affect the feeding habits of an animal? It may change habits because they have different body parts.

What is the consequence of having radial symmetry?

Radial symmetry is the arrangement of body parts around a central axis, as is seen in a drinking glass or pie. Only a few animal groups display radial symmetry. It results in animals having top and bottom surfaces but no left and right sides, or front or back.

How does bilateral symmetry help animals survive?

Characteristics of Animals That Are Bilaterally Symmetrical

In addition to having a more developed nervous system, bilaterally symmetrical animals can move more quickly than animals with other body plans. This bilaterally symmetrical body plan may have evolved to help animals better find food or escape predators.

What animal does not have bilateral symmetry?

Asymmetry. Only members of the phylum Porifera (sponges) have no body plan symmetry. There are some fish species, such as flounder, that lack symmetry as adults. However, the larval fish are bilaterally symmetrical.

What advantage does radial symmetry give to sessile and free floating animals?

For sessile (sedentary) organisms, radial symmetry is useful because the animal can just "sit down" and grab food or detect threats from all directions.

What are the advantages of radial symmetry to a sessile or slow moving organism?

Radial symmetry is advantageous to the slow-moving organisms as in these organisms there is even distribution of all the sensory receptors all over the body. As a result these animals can detect threats from all the directions. Animals with radial symmetry can grab food from all the directions.

Are humans bilaterally symmetrical?

The body plans of most animals, including humans, exhibit mirror symmetry, also called bilateral symmetry. They are symmetric about a plane running from head to tail (or toe). Bilateral symmetry is so prevalent in the animal kingdom that many scientists think that it can't be a coincidence.

What are some possible advantages to an animal being asymmetrical?

Although asymmetry disposes some cells to the deleterious effects of aging, it may also benefit populations by efficiently purging accumulated damage and rejuvenating newborn cells.

Is there an advantage to having a brain at the anterior end of the body?

Concentration of Sense Organs

Well, animals with heads move in the direction of their anterior end. ... So, having the sense organs also at this end allows animals to experience and respond to their environment more efficiently.

What are the possible advantages of an animal having an anterior head with a concentration of sense organs and nervous tissue?

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.
