Natural Selection for $200Natural Selection for $200

Explain how natural Explain how natural selection works on selection works on

individuals but overall individuals but overall populations evolve.populations evolve.

A specific organisms variation gets A specific organisms variation gets selected for. When this occurs the selected for. When this occurs the

organism is able to survive and organism is able to survive and reproduce which then passes on reproduce which then passes on the variation. As time goes on the variation. As time goes on

more and more offspring will have more and more offspring will have the variation so the population the variation so the population

evolves to that variation?evolves to that variation?

Natural Selection for $300Natural Selection for $300

How do variation and How do variation and adaptation relate?adaptation relate?

Variation is what causes Variation is what causes adaptations to occur. If a variation adaptations to occur. If a variation

makes an organism successful, makes an organism successful, then it is considered an adaptation. then it is considered an adaptation.

If the variation doesn’t then the If the variation doesn’t then the species dies off.species dies off.

GiraffesGiraffes

Old population of giraffes had shorter necks. Old population of giraffes had shorter necks. Variation within the population had longer Variation within the population had longer

necks. As food moved higher the longer neck necks. As food moved higher the longer neck variation was more successful while the variation was more successful while the

shorter neck variation died off. The longer shorter neck variation died off. The longer necks reproduced and that variation was necks reproduced and that variation was more common. Over time the longer neck more common. Over time the longer neck variation kept occurring and got selected variation kept occurring and got selected
