Answer 2

Hey SwEeT FriEnD @philoto WeLCoMe tO OpEn StUdY !!

The symmetry of an animal generally fits its lifestyle. For example, many radial animals are sessile forms or plankton and their symmetry equips them to meet their environment equally well from all sides. More active animals are generally bilateral.

The two forms of symmetry, however, are not absolutely separate. A great deal of radial symmetry is proven to emerge secondarily from a bilateral condition (frequently it emerges from animals adapting to a more sedentary lifestyle).

Some animals, such as the sea urchin, are radially symmetrical, but their embryonic development and internal anatomy show that they arose from a bilaterally symmetrical ancestor.

Answer 3

@philoto At the most basic, fundamental level of life, it is just easier and requires less complex cellular development instructions to have symmetric growth.
