- A phenomenon is observed
- A hypothesis is made about how the phenomenon occurs
- A test is developed and performed to determine if the hypothesis is valid
- The results are analyzed
- The hypothesis is revised if necessary and the cycle starts again
Science is not random. Evolution and natural selection have been tested again and again and remain the strongest explanations for the observations we have regarding the origin of life on Earth. Happy birthday, Darwin. You remain an inspiration to scientists everywhere.
