Natural selection is the process by which individuals that are better adapted to their environment survive and reproduce more successfully than less well adapted individuals do.
Overproduction- An elephant can have one baby at a time and six babies in their life span.
Inherited Variation- The baby has a different combination of traits than the parents.
Struggle to Survive- Poachers hunt the elephants for their tusks because they are very valuable.
Successful Reproduction- The tuskless elephants survive and reproduce. Most of the elephants with tusks die and the one without tusks help build the population.
Natrual selection happens here because the elephants are killed based on if they have tusks or not.The elephants reproduce and have one baby. The baby has it's own combination of traits. The baby is a different shade of gray than it's parents. One day a poacher comes to where they are at and shoot the parents. The poacher doesn't kill the baby because it doesn't have tusks. The baby survives and reproduces and makes more tuskless elephants.
