Artificial selection, also known as selective breeding or animal husbandry, is the process by which humans breed only the individuals that have a desired trait in order to make the trait more common. Natural selection is the process by which organisms that are best adapted to their environment are most likely to survive and reproduce. Sort the examples into those that are the result of natural selection versus those that are the result of artificial selection.

Groups:

(a) Natural Selection

,

(b) Artificial Selection

• genetically modified crops
• giraffes' long necks

• cultivation of hybrid corn
• finch beak variations

• breeding of ornamental fish
• development of seedless watermelons
• breeding of racehorses
• domestication of dogs
• camouflage in chameleons

• antibiotic resistance in bacteria

• adaptation of polar bears to cold

• peppered moth coloration
