Is evolution always good?
No, some populations become extinct.
What are mutations?
Change OR Difference in the gene that causes it to be expressed differently
This is another term for selective breeding.
Artificial selection
DJ - This theory is thought to be caused mostly by natural selection and is why species have changed slowly over time.
