Revolution by Natural Selection: A radical history of life from inside our cells
Professor Nick Lane’s research is about how energy flow has shaped evolution over four billion years. He uses a mixture of theoretical and experimental work to address the origin of life, the evolution of complex cells and downright peculiar behaviour such as sex. This lecture will outline how a simple cycle at the heart of metabolism drove some of the most important revolutions in the history of life. By turning gases into organic molecules and back again, this deep chemistry links the origin of life with photosynthesis, the abrupt appearance of animals, cancer, and even the emergence of consciousness.
Nick Lane (PhD, FRSB, FLS) is Professor of Evolutionary Biochemistry in the Department of Genetics, Evolution and Environment at University College London. He was a founding member of the UCL Consortium for Mitochondrial Research, and is Co-Director of the UCL Centre for Life’s Origin and Evolution (CLOE). He was awarded the 2009 UCL Provost’s Venture Research Prize, the 2011 BMC Research Award for Genetics, Genomics, Bioinformatics and Evolution, the 2015 Biochemical Society Award for his outstanding contribution to molecular life sciences and 2016 Royal Society Michael Faraday Prize and Lecture, the UK’s premier award for excellence in communicating science. Professor Lane is the author of five acclaimed books on evolutionary biochemistry, which have sold more than 150,000 copies worldwide, and been translated into 25 languages. His most recent book, Transformer: The Deep Chemistry of Life and Death (Profile/Norton 2022) explores the elusive chemical logic of life.

He didn't talk about life at all! No evolutionist ever does. What makes something alive? Sentient? How do dead, innert, non living chemical elements minerals and organic compounds become 'alive'? The cell has to appear fully formed and fully functional, with all its coding present and we know that's impossible!

I am glad you said "theories" ... a better word would be "hypothesis" ... because there is a zero empirical evidence of how life on this planet originated. Scientists (including Nick Lane) are clueless about life's origin. Nick Lane and his colleague Joana Xavier published the following paper only a few days ago NATURE (FEB 26 2024) Nick and Joana sound very frustrated - here is the ultimate Origin-of-life research reality check: some quotes from their paper: ... Explaining isolated steps on the road from simple chemicals to complex living organisms is not enough … … Most scientists agree that these nanomachines are a product of selection - but selection for what, where and how? … There is no consensus about what to look for, or where … … Did life start on Earth in the hot waters of hydrothermal systems on land or in deep seas? … Combine that with the overarching importance of the question and it’s clear why the field is beset with over-claims and counter-claims, which in turn warp funding, attention and recognition … Strongly opposed viewpoints have coexisted for decades over basic questions … For example, if life started in a warm pond on land, the succession of steps leading from prebiotic chemistry to cells with genes is surprisingly different from those that must be posited if the first cells emerged in deep-sea hydrothermal vents. … Building coherent frameworks - in which all the steps in the continuum fit together - is essential to making real progress. … It is too soon to aim for consensus or unity, and the question is too big; the field needs constructive disunity. Embracing multiple rigorous frameworks for the origin of life, as we advocate here, will promote objectivity, cooperation and falsifiability - good science - while still enabling researchers to focus on what they care most about. Without that, science loses its sparkle and creativity, never more important than here. With it, the field might one day get close to an answer. ...

Charles Darwin and Alfred Russel Wallace are renowned for their contributions to the theory of evolution by natural selection, However, they did not directly address the origins of life itself. The question of the origin of life remains a separate field of study known as abiogenesis, which explores how life may have arisen from non-living matter. While Darwin and Wallace laid the groundwork for understanding biodiversity, they did not address the ultimate origin of life. "In the realm of Particle Physics and Particle Chemistry, a captivating debate surrounds the fundamental constituents of matter, specifically focusing on the intricate building blocks of Quarks: Up, down, charm, strange, top, bottom. Leptons: Electron, muon, tau, electron neutrino, muon neutrino, tau neutrino. Gauge bosons: Photon, gluon, W and Z bosons (mediators of the electromagnetic, strong, and weak forces, respectively).Higgs boson: Associated with the Higgs field and gives mass to other particles. Can we unravel the profound essence of these particles and their interactions, which ultimately sculpt the very fabric of our universe? Delving into the heart of this discourse lies a fundamental question: What are the elemental particles that constitute quarks, electrons, gluons, etc, and how do their dynamic interplays delineate the fundamental architecture of matter? Let's delve deeper into some of the scientific origins and compositions of these fundamental components like: 1. **Ammonia (NH₃)**: Ammonia is a compound composed of one nitrogen atom bonded to three hydrogen atoms. - It is primarily produced through the Haber process, where nitrogen gas (N₂) and hydrogen gas (H₂) react under high pressure and temperature in the presence of an iron catalyst. Alternatively, it can be produced biologically through the decomposition of organic matter by bacteria. 2. **Phosphoric Salts**: Phosphoric salts, such as calcium phosphate (Ca₃(PO₄)₂) or sodium phosphate (Na₃PO₄), consist of phosphorus atoms bonded to oxygen atoms, along with cations such as calcium or sodium. - They are commonly found in nature as minerals, and they can also be synthesized through various chemical reactions involving phosphorus-containing compounds and metal salts. 3. **Heat**: - Heat is a form of energy associated with the motion of atoms and molecules in a substance. - It is typically generated by the conversion of other forms of energy, such as chemical energy (e.g., combustion), electrical energy (e.g., resistance heating), or nuclear energy (e.g., nuclear fission). At the molecular level, heat is manifested as the kinetic energy of particles, causing them to vibrate and collide with each other. 4. **Light**: Light is electromagnetic radiation with wavelengths visible to the human eye, ranging from approximately 400 to 700 nanometres. - It is produced by various natural and artificial sources, including the sun, stars, incandescent bulbs, and lasers. At the atomic level, light consists of photons, which are packets of energy that exhibit both wave-like and particle-like behaviour. 5. **Electricity**: Electricity is the flow of electric charge, typically carried by electrons in a conductor. - It can be generated through various processes, such as chemical reactions (e.g., batteries), electromagnetic induction (e.g., generators), or direct conversion of energy (e.g., solar cells). At the atomic level, electricity involves the movement of electrons between atoms or molecules, creating an electric current. These fundamental components have diverse origins and molecular compositions, ranging from chemical reactions to physical phenomena How do the fundamental components of ammonia, phosphoric salts, heat, light, and electricity originate, and how are their molecular compositions and formation processes brought them into existence ? As we probe deeper into the subatomic realm, we unravel the mysterious dance of quarks, the elementary particles that make up protons and neutrons. Are they truly indivisible, or do they harbour deeper complexities awaiting discovery? Likewise, electrons, the enigmatic carriers of electric charge, stand as solitary entities, yet their behaviour perplexes even the most astute physicists. How do these particles, seemingly devoid of internal structure, exert such profound influence over the properties of matter? And then, there are gluons, the mediators of the strong force binding quarks together within the confines of atomic nuclei. How do these elusive particles govern the stability and structure of the very matter from which life itself emerges? In the grand tapestry of existence, proteins and sugars, the very building blocks of life, find their genesis in the intricate arrangements of these fundamental particles. Can we decipher the profound implications of these subatomic constituents on the macroscopic world, shedding light on the origins of life itself? Thus, the discourse unfolds, as we delve into the depths of particle physics, seeking to unravel the mysteries of existence through the lens of quarks, electrons, and gluons, and their profound implications for the nature of reality and the origins of life." The intersection of science and spirituality has long fascinated scholars and thinkers alike. As we delve deeper into the mysteries of the universe through scientific inquiry, we often uncover awe-inspiring complexities that evoke a sense of wonder and reverence. Some argue that the more we uncover through science, the more we perceive the intricate design and orderliness of the cosmos, which hints at a guiding force or intelligence behind it all - what many refer to as "God." The elegant precision of physical laws governing the cosmos to the intricacies of biological systems, scientific discoveries continually illuminate the grandeur and sophistication of existence. Each revelation unveils a new layer of understanding, prompting reflection on the profound questions of existence, purpose, and the origins of life itself. In this light, some view the pursuit of scientific knowledge as a journey toward uncovering the handiwork of a divine creator. They see the intricate web of interconnected phenomena and the delicate balance of nature as evidence of an intelligent design imbued with purpose and meaning. For them, science is not just a tool for understanding the natural world but a pathway to deeper spiritual insight and appreciation. However, it's important to acknowledge that not all interpretations of science lead to the same conclusions about spirituality or the existence of a higher power. Science operates within the realm of empirical evidence and testable hypotheses, while matters of faith often transcend the boundaries of empirical observation. Therefore, while science may provide insights into the mechanisms and processes of the universe, it can not definitively prove or disprove the existence of God. Ultimately, the relationship between science and spirituality is deeply personal and subjective, shaped by individual beliefs, experiences, and interpretations. In essence, the journey of scientific exploration can indeed deepen our appreciation for the mysteries of existence and inspire a sense of awe and wonder that some interpret as evidence of a divine presence. Yet, the quest for understanding is ongoing, and whether one finds God in the revelations of science or elsewhere remains a deeply personal and profound journey of discovery of the origins of life. "All aspects of the phenomenon are attributed solely to the cognitive processes within his imagination. "In scientific terms, one could state: "The phenomenon is exclusively contained within the neural networks of the individual's brain, Charles Darwin characterized by imaginative constructs that remain unexplained or rejected by many current scientific understanding"

There are other talks where he addresses this, with lists of similarities and differences between archaea and bacteria that point to a strange LUCA. The upshot is basically that no, the commonalities between the two (in various aspects of metabolism, protein translation, RNA replication, etc) point to a common ancestor.

I don't agree with you Prof Lane. You mentioned a lot about bacteria. Let me ask you, many bacteria has got over 2000 proteins. These are not just random proteins but highly interactive proteins. How did random mutations get there and how did natural selection select them. In human brain ypu get 100,000 chemical reactions every second via 50 neuropeptides. These interact with 500 components of the brain in varying combinations which humans even don't understand. How did random mutations and natural selection get there.? When take one step, our brain automatically co-ordinates 200 muscles. Our computer systems can not replicate them. How did the 2 mechanisms get there? DNA most complex code known to man.

=== The first cause singularity for the beginning of the universe was more organized and compact like a wound up clock. Energy flow always decreases with entropy becoming more and more chaotic and unorganized over time. Chemistry and the machinery needed for biological structures for life to exist using amino acids and folding protein molecules are required, using complex geometrically shaped patterns for LIFE to exist was not by accident. The evidence for this and much, much more is proving design. Interactomes and the Ribosome and Chromosomal structures needed for life, along with the memory retrieval systems of DNA/RNA is proving design. Why is everyone, especially the so-called accredited scientists who are towing the line and working so hard to wipe Jehovah God out of existence is beyond reason with willful ignorance and intellectual blindness and prejudice at work here . If one can not see the EVIDENCE for DESIGN, than that is your fault. === Evolution = Self Assembling Atoms = Impossible === Deuteronomy 32 : 5 They are the ones who have acted corruptly.
