1. Adaptations

2. Have you ever wondered how animals are able to survive in the wild? Animals have certain adaptations that help them to survive.

3. Adaptation An organisms ability to respond to change May be structural, behavioral, or physiology Ex: Color Fish eyes that are larger deeper in ocean or even bioluminescent for those at the bottom Beak size to change feeding habits

4. Think about the way you dress in the winter. You don’t wear your shorts and bathing suit when it’s snowing outside! You wear warm clothes, and maybe even a hat and mittens to protect yourself from the weather.

5. And what if you are having a snowball fight? You probably run away from the person throwing at you, and maybe even try to sneak up on that person and throw some snowballs!

6. The way you dress in the winter, as well as the way that you run and hide from someone throwing snow at you are kinds of … Adaptations.

7. Physical adaptations Are body structures that allow an animal to find and consume food, defend itself, and to reproduce its species. Help an animal survive in its environment Hey! I’m a walking stick. I look just like a stick you’d find on the ground. © A. Weinberg

8. Types of Physical adaptation 1. Camouflage (use of color in a surrounding) The chameleon can change its color to match its surroundings. Can you do that?

9. 2. Mimicry- (looking or sounding like another living organism) The Viceroy butterfly uses mimicry to look like the Monarch butterfly. Can you tell them apart? Poisonous Not poisonous Types of Physical adaptation I’m the Monarch! I’m the Viceroy!

10. 3. Chemical defenses (like venom, ink, sprays) Types of Physical adaptation

11. 4. Body coverings & parts (claws, beaks, feet, armor plates, skulls, teeth) Types of Physical adaptations The elephant’s trunk is a physical adaptation that helps it to clean itself, eat, drink, and to pick things up.

12. Behavioral Adaptations… Allow animals to respond to life needs. Are animals’ actions Each organism has unique methods of adapting to its environment by means of different actions.

13. Behavioral Adaptations Divides into two groups: Instinctive Learned These behaviors happen naturally & don’t have to be learned. These behaviors must be taught.

14. Types of Instinctive Behaviors

15. 1.Migration B. 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. a. This is when behavioural adaptation that involves an animal or group of animals moving from one region to another and then back again.

16. 2. Hibernation A.This is deep sleep in which animal’s body temp droops, body activities are slowed to conserve energy. B. E.g. Bats, woodchucks & bears.

17. Example of Adaptation The shape of an animal’s teeth is related to its diet. – Herbivores, such as deer, have many molars(dull teeth) for chewing tough grass and plants. – Carnivores, such as lions, have sharp canines to kill and tear meat.

43. Adaptation Applications: Giraffe Why are giraffes able to go for long periods of time without water? Answer: Giraffes drink water when available, but can go weeks without it. They rely on morning dew and the water content of their food.

44. Adaptation Applications: Giraffe How are their long necks adapted to their lifestyle? Answer: This extra length is thought to have evolved to help the giraffe spot predators and other giraffes in the distance. Interestingly, giraffes and humans have the same number of vertebrate in their necks.

45. Speciation Adapted to heat through lightweight fur and long ears, legs, and nose, which give off more heat. Adapted to cold through heavier fur, short ears, short legs, short nose. White fur matches snow for camouflage. Gray Fox Arctic Fox Different environmental conditions lead to different selective pressures and evolution into two different species. Spreads northward and southward and separates Southern population Northern population Early fox population

46. Known adaptations for sustained powered flight have appeared only three times in the evolution of terrestrial vertebrates: in pterosaurs, birds and bats. – Pterosaurs and Pterodactyls Invading the Air: Flying Reptiles Figure 04A: PterodactyloidsFigure 04B: Rhamphorhynchoids Figure 05: Pteranodon © Paul B.

48. The Origin of Feathers Feathers evolved from reptilian scales for insulation and display – Three major hypotheses for their origin: Feathers were an adaptation for insulating the (presumed) warm-blooded and ground- dwelling reptilian ancestors of birds Ancestral birds were tree-dwelling reptiles that used their developing wings to glide from branch to branch Ancestral birds were ground-dwelling runners whose feathers formed planing surfaces increasing their speed
