Answer:

• Darwin’s theory  of  natural selection  states  that  all  the  organisms have  great capacity  to  reproduce.  
• As a  result population  of  organisms  increases at  high  rate.  
• All  the organisms compete  with  each  other  for  food  and  space.  
• In  this competition,  only  those organisms survive  which  modified  according  to  the  environmental conditions.  
• The nature  selects  only  those  organisms which  are  fit to  live  and  the  remaining  disappears.
• The  selected  organisms live  and  perform  reproduction.  
• They  give  rise  to  the  new species  with  their  own  specific characters.
