Diagram showing the Evolution of Snails by Natural Selection

EXPLANATION:
Organism will Undergo Variation caused by Mutations
Mutated Organism that is Better Adapted to Environment will Survive
They will Reproduce, Pass on Gene and Produce Offspring
Offspring will carry Same Mutated Gene so Overtime, Population of Mutated Organism Better Adapted to Environment will Increase

USING DIAGRAM:
Snails will Undergo Variation caused by Mutations
Snail with White Shell is Better Adapted to Environment as they have Camouflage so will Survive
Snails with White Shells will Reproduce, Pass on Gene and Produce Offspring
Offspring will Contain Same Gene that causes White Shells so Overtime, Population of Snails with White Shells will Increase
