A new find on jellyfish reveals that evolution leads organisms to change and adapt, except when it doesn’t. Yes, you heard that right. Jellyfish, apparently, haven’t changed very much at all since the Cambrian explosion. Apparently, this is due to evolution. While other critters in the same environment are changing because the environment selects it, the jellyfish are surprisingly inert in terms of change over time…because the environment doesn’t select it. IOW, evolution explains everything. If something adapts and changes over time, it’s evolution. If something else doesn’t change and adapt over time, it’s evolution. If a tree falls in the forest, does it make a sound? I don’t know, but it must be evolution anyway. Anything the purports to explain everything, explains nothing and is of no use to science.
