Example of Natural Selection

by stephen kelly

natural selection

The process by which forms of life having traits that better enable them to adapt to specific environmental pressures, as predators,changes in climate, or competition for food or mates, will tend to survive and reproduce in greater numbers than others of their kind,thus ensuring the perpetuation of those favorable traits in succeeding generations.



  • In a habitat there are red bugs and green bugs. The birds prefer the taste of the red bugs, so soon there are many green bugs and few red bugs. The green bugs reproduce and make more green bugs and eventually there are no more red bugs.

This is an example of natural selection through which the red bugs are extinct due to the birds preference in taste. The green bugs reproduce and ensure future generations.


In this example the birds determine the selection.


My opinion is that the red bugs were sweeter than the green and the birds preferred the taste.
