1. GENETIC CHANGES CAUSED BY HUMANS

2. Selective breeding:
Cross organisms with traits you like to get offspring with desired traits

3. Selective breeding:
Humans have been breeding organisms for desired traits for THOUSANDS of years

4. Selective breeding:
Hybridization: Cross organisms with two different good traits to get BOTH traits

5. Selective breeding:
Inbreeding: Cross individuals with similar traits to keep traits pure

6. Genetic Engineering:
Transferring genes from one organism into the chromosomes of another to get NEW traits

8. GENETIC ENGINEERING USES SINGLE CELLS!
Later, the cell splits and forms more cells or a whole organism.

9. There are several concerns
There are several concerns. Many people feel very strongly about genetic engineering.

10. Still, genetically engineered crops are very common:
