- What did Darwin hope to learn about artificial selection? whether you can possibly change the whole species following that specific pigeon into a new species of pigeons.
- There are four principles at work in evolution—variation, inheritance, selection and time. These are considered the components of the evolutionary mechanism of natural selection.
- Variation is needed for natural selection because different traits are needed in order for a species to survive different circumstances. Overproduction is needed because many offsprings will increase the chances that some will survive.
