A scientist puts 100 houseflies in a sealed container; then sprays an insecticide into the container.  Ninety-six of the flies die.  Four survive.  The scientist lets the survivors mate and produce offspring, then repeats the experiment with 100 offspring.  Fifty-six of them survive the spray.  This experimental result is evidence of – 

• adaptive radiation 
• speciation
• natural selection
• extinction
