Which bird was most successful in the first 500,000 years? why do you think so? what kinds of mutations were more beneficial? why? which bird(s) was/were most successful after 1,000,000 years? why were they more successful? how similar or different were the birds after 1,000,000 years compared to the original bird characteristics you chose? why did they change that way? (think about the environments you created in the second part.) which characteristics do you think affect the overall survival of the bird? why? how does this activity simulate natural selection?
