write a detailed note on theories of origin of life.
Dear Student,
The 7 theories of origin of life on Earth, are as follows :
1. Theory of primordial soup
2. Theory of electric spark or consecutive creation
3. Theory of community clay
4. Theory of biopoesis or abiogenesis
5. Theory of spontaneous generation
6. Theory of RNA world
7. Theory of panspermia
​Due to paucity of time we are not able to provide you the details of every theory. Here, we are providing you the details of two of the above mentioned theory.
Theory of RNA world- It is believed that RNA, which is able to store information similar to DNA, served as an enzyme like proteins, and it then helped in creation of both DNA and proteins. Much later, DNA and proteins being more efficient, succeeded this "RNA world," . This is also called RNA hypothesis.
Theory of panspermia- Some scientists suggested that the origin of life did not begin on Earth. The life was brought to earth from someelsewhere in space, and this notion is called as panspermia. As a number of Martian meteorites have been found on Earth , it lead some researchers suggested it controversially that those meteorites brought microbes over earth and from that the origin of life began.
You can read about the rest and if you find any difficulty, you can get back to us.
Regards.
