the fossil record is a joke,,
the rocks age is determined by the age of the fossils and the fossils age is determined by the age of the rocks,,
give me a ******* break,,
See post #16.
Biological evolution is supported by 18 converging lines of scientific evidence, with several million data points.
Fossils can be analyzed with new technology that lets us sequence the DNA "in situ" without removing it from the rock.
It's not the age that matters, it's what we see in the DNA. Evolution is a continuous process, the combinatorics never stop. What we are looking for is the "catastrophes" (Google Rene Thom, there's only 7 of them in 3 dimensions).
Catastrophes are what used to be called "leaps" in evolution - also referred to by various other monikers like "saltatory" and so on. Our understanding of these processes comes mainly from nonequilibrium thermodynamics (for example, Google the Belousov-Zhabotinsky reaction, which received a Nobel prize in the 70's). However catastrophes are also relevant in many other areas of science, including lately neuroscience and the "critical brain" theory.
By comparing two fossils we can sometimes "infer" the catastrophe that created an advanced life form. This is complex science, data analysts spend lifetimes poring over the evidence, and it's one of the areas where AI and machine learning has been enormously helpful.
This process of "catastrophic recombination" manifests in our brains as memory. Just last week we discovered how RNA is involved in memory traces in the nucleus accumbens of human beings. And in this one week, scientists at MIT have developed an animal model to study it. So far it appears to work almost exactly like the immune system. If you think of our immune system "figuring out" which antibody it has to use to fight off an infection, this is how our brains "figure out" which RNA it has to use to represent a memory. Apparently this is what sleep is for - the temporary neural traces get converted to permanent RNA memories during sleep, and in other quiet moments when the brain is idling.
Biophysics is what tells us which protein shapes are needed to accomplish geometric catastrophes, and which catastrophes then affect the transcription processes downstream. Ultimately it's all a result of combinatorial evolution. Which in turn is made possible by the ability to "count" discrete quanta in continuous spacetime. Life is built in to the fundamental physical structure of the universe. In a way one could say the entire universe is "alive" this way.
None of this knowledge would have been possible without the basic understanding that life evolves.
