    I would like to thank the moderator for their recognition of all the people working behind the scenes. The quality of the questions asked by well respected colleagues is a testament to Professor Lane's natural ability at presenting complex and challenging science. If we answer a few baffling questions in this life and leave better questions to others, it seems we are all well served.

    I am an unabashed fan of Nick Lane after stumbling on his book, "The Vital Question" about six years ago, and "Transformer" was equally engaging, compelling and inspiring. Thank you for this fascinating panel of experts in fields essential to the study of the origins of life.

    I have started slowly working my way through "Transformers" a second time. So glad this presentation popped up now because what I have learned from this excellent lecture will help me (a "normal" person) understand more of Dr Lane's fascinating hypothesis and how it came to be as he describes it in his wonderful book. Thank you very much!

    Nick that was a beautiful, elegant and compelling hypothesis for how autotrophic life could have developed supported with tantalising evidence. All the physical and chemical ingredients are there. Anyone can think of chemical additions from space but your hypothesis hangs together. Go you good thing (and your students!)

      The Age of Life
      The ability to carry out actions differentiates inanimate matter from living matter. In turn, every action involves the management of Information.
      We do not know what Matter is or what Life is, and we assume that all life forms that currently inhabit the planet descend from a common ancestor (LUCA), an organism whose complexity is evident if we consider that it is attributed the ability to reproduce. Due to the above, it is reasonable to assume that “seeds of life” existed prior to LUCA. Assuming that the “seeds of life” emerged together with the Big Bang is a bold postulate, and as such requires a solid empirical foundation. When observing Evolution considering the information that our ancestors have managed, and that currently managed by humanity, it is possible to distinguish seven evolutionary milestones; Its analysis allows us to postulate that Life goes back to the origin of the Universe, and the existence of an “evolutionary pattern” is evident, which turns out to be the Golden Ratio.
      Evolutionary Milestones
      -Emergence of ”Seeds of Life”(1) (thirteen thousand eight hundred million years ago).
      -Emergence of LUCA (Last Universal Common Ancestor) three thousand eight hundred million years ago
      -Emergence of the brain (five hundred and fifty million years ago).
      -Emergence of what was the precursor of human language (2) (twenty-seven million years ago)
      -Emergence of the language that characterizes us(3) (around two hundred and twenty thousand years ago).
      -Emergence of “the information age” with the transistor (1950)
      -Evolutionary Singularity(4) proposed by Ray Kurzweil, who postulates that humanity will access a Singularity as a result of the exponential growth of information management (year 2045).
      Evolutionary sections
      Among successive evolutionary milestones we can distinguish the following six “Evolutionary Tranches”, with the duration indicated (in years):
      Tranche 1: 10,000,000,000 (13,800,000,000 - 3,800,000,000 = 10,000,000,000)
      Tranche 2: 3,250,000,000 (3,800,000,000 - 550,000,000 = 3,250,000,000)
      Tranche 3: 523,000,000 (550,000,000 - 27,000,000 = 523,000,000)
      Tranche 4: 26,780,000 (27,000,000 - 220,000 = 26,780,000)
      Tranche 5: 219,905 (220,000 - 95(5) = 219,905)
      Tranche 6: 95 (95 - 0 = 95)
      The particular variation experienced by the Evolutionary Sections over time suggests using the logarithm of said sections (LT) to analyze their behavior over time. The logarithms in question are as follows:
      LT1 = 10.0000
      LT2 = 9.51188
      LT3 = 8.71850
      LT4 = 7.42781
      LT5 = 5.34224
      LT6 = 1.97772

      The lines between two successive logarithms have the following slopes (P)
      P1 = -0.48812 (9.51188 - 10.0000 = -0.48812)
      P2 = -0.79338 (8.71850 - 9.51188 = -0.79338)
      P3 = -1.29069 (7.42781 - 8.71850 = -1.29069)
      P4 = -2.08557 (5.34224 - 7.42781 = -2.08557)
      P5 = -3.36452 (1.97772 - 5.34224 = -3.36452)
      After searching for an “evolutionary pattern” we will determine the variation between successive slopes, which is given by the Ratio (R) between them, that is, P2/P1; P3/P2; P4/P3; P5/P4, and is the following:
      R1 = 1.62538
      R2 = 1.62682
      R3 = 1.61586
      R4 = 1.61324
      The above values differ from the Golden Number (1.61803), a number also called the golden number, the number of God, the extreme and average ratio, the golden ratio, the golden mean, the golden ratio and the divine ratio, by 0.45%; 0.54%; 0.13% and 0.30%, respectively. In turn, the average of the sum of the ratios is 1.62032. This value differs from the golden ratio by 0.14%.
      The results obtained allow us to postulate that Evolution follows a pattern that is a function of Information and the golden ratio, and that Life goes back to the origin of the Universe.
      (1)The last universal common ancestor (LUCA) is the putative common ancestral cell from which the three domains of life, Bacteria, Archaea and Eukarya, originated. The complexity that LUCA is assumed to have does not give rise to affirming that it arose by “spontaneous generation”, it being valid to postulate the pre-existence of “seeds of life” prior to the emergence of LUCA; It is postulated that the origin of the “seeds of life” dates back to the moment when Matter arose in the Universe, that is, around thirteen thousand eight hundred million years.
      (2)“We find that the anatomical potential to produce and perceive sounds differentiated by their formants began at the latest by the time of our last common ancestor with Old World monkeys (Cercopithecoidea) about 27 Ma ago”; " Which way to the dawn of speech?: Reanalyzing half a century of debates and data in light of speech” (Science magazine)
      (3) The last change in the position of the hyoid bone in humans, which would have allowed access to the language that characterizes us, took place approximately two hundred and twenty thousand years ago, and its data is based on archaeological evidence and anthropological studies. There is no scientific source that records this change on an exact date.
      (4)Due to the exponential growth of information technologies, Ray Kurzweil postulates that a Technological Singularity will occur in the year 2045, at which time technological growth will be so rapid and so profound that it will be impossible to predict what its consequences will be.
      (5) It is the time between 1950 and 2045, the latter year in which Ray Kurzweil postulates that a Singularity will take place.
