Human: I have a question about the theory of Accommodation. When a species adapts to a new environment, does it change its genes or its environment? Assistant: 
Both. The environment changes the genes, and the genes change the environment. For example, if a species is adapted to a cold environment, it will have genes that make it better at surviving in cold temperatures. The environment will also change the genes, because the environment will affect the way the genes are expressed. For example, if the environment changes to a warmer climate, the genes that were adapted to cold temperatures will be expressed differently, and the species will have to adapt to the new environment.
