It is beneficial for a giraffe to have a long neck to reach their food. So, overtime the giraffes stretched their necks to reach their food and thus they GOT longer necks. Is this how natural selection works. Is this an example of a Darwinian idea or a Lamarckian idea?
No Lamarckian idea......Natural Selection is a PASSIVE PROCESS. It is NOT something that is done to you.
