• more fossils
• better environments
• less evolution

How is natural selection in the evolution of long necks in giraffes best explained?

• Shorter necked giraffes were likely killed by long necked giraffes.
• Giraffes with longer necks survived because they were better suited to their environment.
• Long necked giraffes mated only with other long necked giraffes.
• Giraffe necks grew longer because of the bone structure of the animals.
