Where humans have bred organisms together based on traits we like.

• Evolution
• Natural Selection

It is very common for yellow labs to have bad hips. This is because owners want purebred yellow labs who are good hunting dogs.  This is an example of 

• Natural Selection
• Selective breeding
• Mitosis
• Fossil Record

Problems with selective breeding include

• Better animals
• More Meat
• Animals can have bad health problems
• more diversity
