Answer:
Organisms change over time due to natural selection and genetic mutations.
Step-by-step explanation:
An example of natural selection is the finches the scientist Charles Darwin studied in the Galapagos Islands. The finches had different shaped beaks which allowed them to adapt to different environments. An example of genetic mutation is if a person had an extra finger.The past helps us predict the future because if a change happened in the past to an organism, we can use the same change and apply it to other organisms which can help us determine what is to come in the future. Hope this Helped!!
