2  Meaning of species  Evolution of species.  Speciation process.  Proof to ascertain speciation.  Natural selection.

3  Birds developed from a two- legged running dinosaurs called theoropods.  Every component of a bird has develop to enable them to fly.  Over 10,00 kinds of birds have the ability to fly  Two birds that are incapable to fly are the ostrich and the penguin.

4  Birds breed with different species of birds and become a new species.  Genes.  Geographic position.  Sexual selection.

5  Non-genetically bases changes of mate  Various species of one bird

6  Variation-difference in look and behavior.  Inheritance- characters from parents are transferred to their offspring  High rate of population growth- some reproduce more than others  Differential survival and reproduction- individuals learn processes that will help them with the fight for local resources and will produce more offspring.

7  Explained species.  Evolution of species through time.  The method of natural selection in species.  Speciation device
