And yet, go try to find out an age for the origin of life on Earth. You'll find that ALL of the evidence is faint morphological features in rocks from Australia. It's the gold standard for one field, but circumstantial in another?
- dekhn 6y agoNot correct, the data on earth that is reliable is based on carbon ratios, which are a far better hallmark. The older morphological stuff, while fun, is really just speculative, still.
- garmaine 6y agoNot for origin of life, no. We’re talking >3gy. These fossils are rocks, not biomaterials. Isotopes of trace decay products in the rock itself are used to age it, as is done with other geologic samples.
