1 Adaptations

2 Types of Adaptation Anything that helps an organism survive in its environment  Adaptations are inherited from their parents It also refers to the ability of living things to adjust to different conditions within their environments.  Structural adaptation Behavioral adaptations Physiological adaptations

3 Structural adaptations
A structural adaptation involves some part of an organism's body. Teeth Body coverings Shells Quills Scales   Camouflage Mimicry A structural adaptation involves some part of an animal's body, such as the size or shape of the teeth, the animal's body covering, or the way the animal moves.   Teeth - since different animals eat different things, they don't all have the same kind of teeth Body coverings - Hair, scales, spines, and feathers grow from the skin.  All of these parts help animals survive in their environments.   Movement - animals find food by moving from place to place

4 Camouflage Camouflage allows an animal to blend into its environment.
Makes it hard for predators to single out individuals  

5 Mimicry Mimicry allows one animal to look, sound, or act like another animal to fool predators into thinking it is poisonous or dangerous.   Coral snake (left) very poinsonous & Milk snake (right)

6 Behavioral adaptations
Behavior adaptations include activities or behaviors that help an animal survive.  Innate Learned Survival Seasonal Behavior adaptations include activities that help an animal survive.  Behavior adaptations can be learned or instinctive. (a behavior an animal is born with). Social behavior - some animals live by themselves, while other live in groups.  Behavior for protection -  An animal's behavior sometimes helps to protect the animal.  For instance the opossum plays dead.  A rabbit freezes when it thinks it has been seen. 

7 Innate vs. Learned Innate Learned Inherited through the genes Examples
Flying for bees, birds Swimming for fish Walking for humans Speaking for humans Learned from experience or from observing other animals Examples Type of language spoken for humans Riding a bicycle

8 Survival Behavior Parenting Finding food Predator-Prey adaptations
Predator-animals that eat other animals Prey-animal being eaten Marking Territory Way that animals inform other animals that an area is occupied Defensive Action Protect resources, themselves, food, mates, offspring Courtship Behaviors used to find a mate Parenting Depend on parents for survival

9 Seasonal Behavior Help organisms adapt to the environment Migration
Hibernation Estivation Biological Clock

10 Migration Animals migrate for different reasons.
better climate better food safe place to live safe place to raise young go back to the place they were born. Adaptation that involves an animal or group of animals moving from one region to another and then back again.  Migration-is the behavioral adaptation that involves an animal or group of animals moving from one region to another and then back again.  Animals migrate for different reasons.  The reasons are as follows. better climate better food safe place to live safe place to raise young go back to the place they were born. I can explain how an adaptation helps an organism survive in a particular environment.

11 I can explain how an adaptation helps an organism survive in a particular environment.
Hibernation Period of inactivity in which animal’s body temp., heart rate, and breathing rate slow down to conserve energy. Bats, woodchucks & bears. Hibernation- is a deep sleep in which an animal's body temperature drops to about the temperature of the environment.  Body activities, such as heartbeat and breathing are slowed causing the animal to need very little food.  Animals that hibernate are  bats  woodchucks snakes  bears. During the hibernation the animals live off of the fat that is stored in their body. 

12 Estivation Period of inactivity in the summer
I can explain how an adaptation helps an organism survive in a particular environment. Estivation Period of inactivity in the summer hot, dry places Snakes, lizards, frogs, toads

13 Biological Clock Internal control of animal’s natural cycle
I can explain how an adaptation helps an organism survive in a particular environment.

14 Physiological Adaptations
Behaviors controlled by the brain Reflexes Blinking Pain Swallowing Tolerance to a certain poison Logical thinking

15 Natural Selection and Population Changes Over Time

16 Natural Selection The process by which individuals are better adapted to their environment “Survival of the Fittest” The fittest survive to pass on their traits to the next generation. Examples: Insecticide resistance Speciation Galapagos finches

18 Insecticide Resistance Speciation
I can explain how genetic variations within a population help an organism survive longer. Insecticide Resistance Speciation

19 Genetic Variation Differences that exist naturally among the members of a species Some traits are better suited than others to survive in their environment I can explain how genetic variations within a population help an organism survive longer.

20 I can explain how genetic variations within a population help an organism survive longer.
