But in today's environment, it is favorable to get an education and have a baby at a later age. Why is the EEA sometime different from a populations current environmentcorrect answer- Culture Environments can change rapidly Natural Selection is slow Bacteria are more likely to be in their EEA cuz they have a short generation time, so NS is working relatively faster to their changing environment Describe 3 examples of species having dif current environment and EEAcorrect answer- Zoo animals are dif than their EEA, they get medicine, no predators
