Скачать или смотреть Oparin Haldane theory/ Modern theory of Origin of life

Welcome back to the channel! In today’s video, we dive deep into one of the most profound questions in science: How did life begin? While many are familiar with basic Darwinism, the Modern Synthetic Theory of Evolution provides a much more comprehensive look at the "Origin of Life." We explore the transition from complex chemistry to biological life, breaking down the milestones that turned our primordial Earth into a living planet.
In this video, we cover:
The Oparin-Haldane Hypothesis: How a "primordial soup" set the stage for life.
Chemical Evolution: The step-by-step process of inorganic molecules becoming organic.
The Miller-Urey Experiment: The groundbreaking proof that life’s building blocks can be created naturally.
The Modern Synthesis: How genetics and natural selection work together to explain the diversity of life today

Life / Naturalistic theory or theory of chemical evolution.
Exploration was done by Oparin and Haldane
Experimentation by Urey and miller
Primitive earth conditions
The atmosphere was reducing type i.e. no free was available. H-abundent (arrow from reducing type)
Whatever O_2 was present, it was in bound form in form of metal oxides.
There was no ozone: O_2 \xrightarrow{uv} O^\cdot + O^\cdot, O_2 + O^\cdot \rightarrow O_3
Temperature was very high (4000^\circ C)
There was abundance of methane, ammonia, water vapors.
following energy source (bond formation)
Heat from volcanic eruptions
Lightning from clouds
UV rays and X-Rays.
Life originated in water because water is an solvent and provides maximum chances for interaction.
