Evolution is best described as:

• A sudden and massive loss of species on the planet due to climate change

• A harmful mutation in a species

• The gradual change and development of species over time, arising from a common ancestor

Which of the following statements ​best​ describes how the fossil record shows evidence for evolution?

• The fossil record shows the remains or traces of ancient life forms

• Fossils exist all over the world
