It allows different parts of the body to become specialized in different ways. This is called cephalization.
Many invertebrates such as insects, arachnids and other arthropods have bilateral symmetry. This means they have symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side. However, some invertebrates such as jellyfish have radial symmetry. Animals with radial body symmetry display a regular arrangement of body parts around a central axis, usually in a circular pattern.

False
It not just has a line of symmetry; a perfect circle has an infinite number of lines of symmetry.
Evolution is descent with modification. Or, change over time. And formally as the change in allele frequencies over time in a population of organisms. This is an observed and a observable fact. The theory is; the theory of evolution by natural selection, which explains the fact of evolution. Natural selection is the main mechanism ( there are others ) that drives the adaptive change in organism that can lead to speciation, or just simple evolution.
