PPT-Natural Selection and Adaptations

OBJECTIVES Today you will be able to Explain the process of evolution by natural selection Explain adaptation What exactly is evolution in THIS class Evolution a change in the GENETIC. How Animals Survive. Types of Adaptations. Physical Adaptations. The way an animal’s body is made. Behavioral Adaptations. The way an animal acts or behaves. Physical Adaptations. Smooth Skin. To glide through the water. Are changes in physical forms or behaviors brought about by natural selection that enable an organism to better survive in its natural habitat.. Many adaptations have to do with getting food and oxygen, moving or staying in one place. G7- I can list examples of changes in genetic traits due to natural and manmade influences. What is Natural Selection?. Write it on your white board. Which of the following is an example of Natural Selection?. . Plants have adaptations to help them survive. The cactus shows lots of desert adaptations. Long root systems spread out wide or deep for water. A cactus stores water in it’s spine. Some cacti have white hair to help shade the plant.
