Evolution

Final Jeopardy QuestionFinal Jeopardy Question

• Gazelles on the African plains are often hunted by the top predators. Over time, the gazelles have evolved to have very large eyes on either side of their head and very large ears. – How do their eyes and ears factor into their

survival?– Explain how, through Natural Selection, gazelles

have evolved to have these kind of eyes and ears.

Final Jeopardy AnswerFinal Jeopardy Answer• The eyes on either side of the head help them

to see the predators coming from all directions. The large ears help them to hear the predators.

• Over time, the gazelles that had poor hearing and vision were killed off. Those with better vision and hearing survived to pass those traits on to their offspring.
