2 Standard XII- Animal Adaptations CONTENT STANDARD 12. Describe protective adaptations of animals, including mimicry, camouflage, beak type, migration, and hibernation.ELIGIBLE CONTENTA. Recognize and apply the definition of mimicry. (The resemblance of one organism to another or to an object in its surroundings for concealment and protection from predators.)B. Recognize and apply the definition of camouflage. (The method or result of concealing by disguise or protective coloration such that the organism appears to be part of the natural surroundings.)C. Distinguish between different beak types, and identify what each type is used for.D. Recognize and apply the definition of migration. (The process of changing location periodically, especially by moving seasonally from one region to another.)E. Recognize and apply the definition of hibernation. (The process of passing winter in an inactive or dormant state.)
3 EvolutionChanges in an organism over time known to occur due to fossilsAdaptation- Evolution of a structural, internal or behavioral feature to better suit the organism for survivalResults from a change in the environmentTheory of Natural SelectionSurvival of the fittestCauses a change in the gene poolUnfit genes die out or are bred out
4 Structural Adaptations Mimicry- Copying of the appearance of other organisms for protection or other advantagesProtective resemblance- Normally resembles plant structuresCamouflage- Body color blends in with surroundingsSpots and stripes break up body patternWarning Coloration- Bright coloration to warn of dangerMechanical Defenses- Physical covering that allows for defending from predators or to aid in predationEx: Claws, sharp teeth, quills, shells, etc.
6 Adaptations Charles Darwin Father of evolution Developed theory of natural selectionTraveled on the H.M.S. Beagle to the Galapogos IslandsStudied finches and beak size and shapeBeaks of birds are adaptations for food type
9 Bird Wing AdaptationsPenguin wing adapted for swimming
10 Behavioral Adaptations Migration- Movement of an animal from one place to anotherCommon in birds and grazing mammalsBrought on by climate changeHibernation- Period of dormancy during certain time-periodsCommon in reptiles and mammals of cold climates
