Fossil Evidence of Ancient Balloon Animal Discovered
New fossil evidence reveals a balloon-like creature that lived about 520 million years ago. Read more from LiveScience. This discovery highlights one of the issues with fossil evidence and the approach to science in general. Parsimony and scientific attitude in general tells us to not believe or suggest creatures that we have no evidence of yet we continue to find evidence of new creatures all of the time. And more than that the animals that we know roamed the earth in large populations we only find a few fossils of. If a fossil simply goes undiscovered we say it does not exist. This leads to issues when we have limited evidence of a new species, scientists will oppose even the idea of it without hard evidence which may remain elusive for decades.
