Final answer:
Artificial selection, observational studies of natural selection, and experimental studies on organisms provide evidence for evolution by demonstrating genetic variations and natural selection.
Step-by-step explanation:
Experiments that provide evidence of evolution include: artificial selection where humans selectively breed plants or animals for certain traits, observational studies of natural selection in action, and experimental studies on various organisms to observe evolutionary changes over generations.
The results of these experiments support evolution by demonstrating how traits can change over time and how organisms can adapt to their environments through genetic variations and natural selection.
