Decades-Long Mystery Solved: Starfish Unveiled as Walking Heads
Scientists have solved the centuries-old mystery of the location of a starfish's head. Contrary to previous assumptions, starfish do not have a single head positioned at the center of their bodies. Instead, they have head-like regions in each of their limbs, as revealed by genetic studies. This discovery challenges the traditional understanding of animal symmetry and raises questions about the nervous system and brain development in starfish. The study of echinoderms, which include starfish, has the potential to provide insights into the evolution of life on Earth and various mechanisms of species' health maintenance.
