<human>:  I have a question about the development of intelligence. How did the first intelligent life form come to be?
<bot>: The first intelligent life form came to be when a single cell organism evolved the ability to use its environment to its advantage. This is called natural selection. Natural selection is the process by which organisms with certain traits are more likely to survive and reproduce than organisms with other traits. This process is driven by the environment, and it is the reason why some organisms are more successful than others.
