The question that is given over here, it says that we have to describe the theory of chemical evolution.
00:21
The theory of life origin is known as the chemical evolution.
00:26
In this idea, the pre -biological changes.
00:39
It slowly transformed the simple atoms and molecules into a more complex chemicals that are, needed to produce life.
01:05
Regarding the evidence, there are five major evidence that supports the evolution theory that is embryology, molecular biology, comparative anotomy.
01:45
And then they are asked to describe the stages that involves in the process of the theory of chemical evolution.
01:59
The first stage is the organic molecules like the amino acids and nucleotides.
02:13
They were formed first and there are all the recursors of the lab.
02:23
And then in the second stage, simple organic molecules are synthesized.
02:39
And in the third stage, complex molecules that are enclosed by membranous structures.
02:48
It led to the formation of the form.
02:50
Cell light structures.
03:00
In the fourth stage the cell characteristics they became more defined as the membrane structures and they became more chemically selective and developed the unique properties...
