After traveling to the Galapagos Islands, Charles Darwin discovered unique inherited traits that were common among [1]____of organisms only found in these islands. He noted that these traits enabled the populations to survive better in their environments. He called these traits or advantages [2]___. New species may form or evolve based on their environments. Therefore populations of the SAME species may evolve differently if they are not able to breed with one another. This is called [3]____ and can be caused by geographic isolation or reproductive isolation. Modern evolutionary scientists have noted differences in how species evolve. Evolution has been described as a change over a long period of time. This is called [4]____. Another evolutionary model suggests that evolution may occur in spurts due to environmental pressures.
