Pardon, I'm approaching this with little knowledge beyond the wiki page for symmetry in species. It says it's been suggested that either symmetry could've evolved from the other, but I'm wanting to know how/why you think/know radialism could evolve from bilateralism (and examples, if possible). I'm interested in loosely designing a species that's in the process of evolving out of a previous bilateral design, and almost completely radial by the point in time I refer to them. I'm just having difficulty imagining how that would work, what with the unconcious bias towards symmetry as a human, and would appreciate real life examples from a community that understands evolution far better than I. Any advice or suggestions are appreciated submitted by /u/mycotian [link] [comments]
