he Canvas module described an example of sympatric speciation due to habitat specialization: A population of flies that lives in a forest with two main types of trees: some with red apples and some with green apples. Some individual flies only feed on red apples while others exclusively feed on green apples. In this hypothetical scenario, red apples are more nutritious than green apples, such that flies on the red apple mature quicker than flies on the green apples. This leads to temporal isolation as flies will be ready to mate at different times. In this example, must the choice to eat red or green apples be heritable for speciation to likely occur
