Scenario:Fossils show that many species, or kinds of organisms, have died out or become extinct because they could not respond to the pressures fast enough to survive. Those that did survive were better suited to their environment. Evidence shows that new species develop from old species as a result of gradual change. Natural selection is one process by which organisms change over time. Evidence shows that species change over time, sometimes giving rise to new species.External DataPrompt:Look at the pictures above that show how the giraffe got such a long neck. Write a scientific explanation of how natural selection applies to this process.

Claim:____________________________________________

Evidence:______________________________________________
