What evidence does speciation provide for the theory of evolution by natural selection?

• Speciation can show us that new species don't choose to adapt, but have changed due to diverging from an original species due to reproductive barriers.
• Speciation can show us that new biological species can come from divergence (separating) due to reproductive barriers.
• Speciation can show us that environmental changes & genetic variation play a role in the process of a new species diverging from an original species due to reproductive barriers. 
• All of the above fit!
