Jellyfish enhance their skills by building a virtual wall
Two jellyfish genomes differ “as drastically as humans do from sea urchins.”
Convergent eye evolution shows that evolution is “easy”?
Here’s an inventive turn of phrase from Nature: “Eye evolution came easy for simple sea creatures Family tree shows that jellies and their relatives evolved eyes independently at least eight times.” Jellyfish and their kin have no brains and make do with rudimentary nervous systems. But an analysis now shows that these simple sea creatures evolved eyes multiple times, transforming basic precursor cells into a wide range of useful visual systems. Curr. Biol. (2018), “Eye evolution came easy for simple sea creatures” at Nature Nothing like a bold approach to the problems of irreducible complexity! Imply, without stressing the point, that if the creatures were “simple,” the process must have been “easy” and therefore wthin the range of random Darwinian Read More ›
