2. What are the four principles of natural selection?
3. Why must there be variation in the population in order for natural selection to occur?


Sagot :

Answer:

  1. 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.
  2. 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.
  3. 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.
