| This shows that they evolved from normal ancestors and only secondarily reverted to radial symmetry. |
| Some of our rectangles had radial symmetry, while others achieved asymmetrical balance. |
| At this stage, the blastula is in the form of a hollow sphere with radial symmetry. |
| If you were to watch an embryonic starfish develop, you would see that it begins life bilaterally, but switches to radial symmetry as it matures. |
| A variant has also been developed to acquire metabolite maps from plants with high radial symmetry. |
| However, Rayor suspects that for webs with radial symmetry, the answer is a matter of biodynamics. |
