Here we show how the Third Evolution shares many characteristics with the Second Evolution: the blindness, the randomness, the digital base, the unicity, the diversity, the role of the environment, the inheritance. Today we deal with unicity.
The Unicity
The Universe (First Evolution) is unique. Wherever we observe the Universe, it looks statistically homogeneous. The laws of physics seem to apply everywhere: the transition levels of hydrogen are always the same, except for light propagation effects (whether gravitational like lensing or redshift, or electromagnetic). The physical constants apply to the whole Universe. For the time being, the best explanation we have got for this lies at the very beginning of the Universe, where a period of inflation has allowed all parts of the known Universe to be connected.
Life (Second Evolution) is unique. Every cell of living organisms uses the same replication DNA-based system. It might not have been the case at the beginning: probably an RNA-based system or even a simpler system may have existed. But this has disappeared, and only one form of life exists on Earth today.
The Third Evolution is carried by the human species. It is now established that Homo Sapiens (HS) is a unique species. Neanderthal species has disappeared... The human brain has emerged from the Second Evolution, but something different is now happening: problem-solving is not left to the slow-process that is life-based tinkering evolution. Artefacts and writings are now massively increasing, outside living organisms. They are only produced by one species: Homo Sapiens. Scientists have shown that HS is rather special, not on the brain mass, but on the ratio of brain mass to total mass.
On that measurement rod, mice fare as well as humans! An even better predictor of "intelligence" is now thought to be the forebrain neuron count.
