What do you mean by biogenesis ?

Dear Student

The formation of a new living organism by the pre-existing living organism is called biogenesis. 

While earlier when scientists were trying to understand how life has evolved on earth, various theories were put forward by different scientists. Louis Pasteur explained the origin of life as spontaneous from mud, straw, etc. 

  • To counteract this theory of spontaneous generation, Rudolf Virchow explained the origin of life from pre existing living organisms.

Life cannot arise spontaneously on the primitive earth billions years ago. The formation of living beings from living organisms only is called as biogenesis.
Different scientists like F.Redi, A.Spallanzani and Louis Pasteur advocated the theory of biogenesis of evolution of life forms on primitive earth.
