Frequently asked in IGCSE Biology: comparison of natural selection and selective breeding
Both processes result in genetic changes over time, but there are many differences in how the genetic changes are achieved.
Natural selection is the key mechanism that is responsible for the evolution of organisms over generations.
This is how natural selection occurs:
Selective breeding is the method that humans use to improve characteristics of organisms to breed (e.g. cows that produce a lot of milk, disease-resistant crops)
This is how selective breeding occurs:
