Unit 1 Lesson 4 Natural Selection and Evolution!!
Natural Selection// This was created by Charles Darwin!
Natural Selection is the idea of population of a given species, some of the organisms ( the species) will have traits, or adaptations to help it survive. The organism that survive will then pass their traits onto the next generation, and these traits will become more common. As these certain traits become more common, the appearance of the animal will change. A good example would be a Giraffe. Over time their necks will grow longer so they will survive more than the short neck ones. They would die out, because they wouldn't be able to get the food they need.
