Some organisms have favorable traits that are well-suited to their environments. Organisms with this advantage are more likely to thrive, reproduce, and pass their traits to future generations than organisms without favorable traits. This process is known as

• genetic engineering

• natural selection

• selective breeding

• artificial selection
