A:

Hi Parth,

Conclusions from Darwin’s theory of evolution:

  • Although all the species produce a large number of offspring, populations remain fairly constant naturally. This occurs due to the struggle to obtain food, space and mate.
  • Only those organisms who are fit for the changing environment have the right to survive. The organisms which are unfit are eliminated and ultimately die.
  • The fit species reproduce. The essential variations in the characteristics are passed on from one generation to the next. These variations make them fit to survive in the constantly changing environment.         
  • In the struggle for existence, the organisms that develop new favourable characteristics will survive in the long run. The organisms who survive will transmit the favourable characters to their offspring. These characters get accumulated and give rise to new species.
