EVOLUTION OF SPECIES

                   EVOLUTION OF SPECIES

ALL LIVING THOINGS ARE BORN,THEN THEY GROW,REPRODUCE,AND DIE. LIVING ORGANIMS CHEANGE OVER TIME. THIS FISH HAD STRONG FINS, GILLS TO BREATHE UNDERWATER LIKE  MOST FISH,MANY GENERATIONS BEGAN TO ADAPT THEMSELVES TO THEIR NEW ENVIROMENTS.THE FISH IN THE EXAMPLEADOBE BEGAN TO LOSE  ITS GILLS AND DEVELOP ITS LUNGS, PLUSIT TRANSFORMED ITS FINS TO LIMBS MORE SUITED TO A LAND HABITAT.

SIMILARY AMPHIBIANS BECOME THE OF REPTILES AS WELL AS OF DINOSAURS, SNAKES, AND CROCODILES.REPTILES EVOLVED   INTO BIRDS MAMMALS.UNDERSTAND EVOLUTION IDENTIFY SIMILARITIES AND DIFFERENCES BETWEEN TWO OR MORE SPECIES COMPARE (1) BODY PARTSBONES AND TISSUE. (2)FUNCTIONS, RESPIRATION, REPRODUCTION, PHOTOSYNTHESIS. (3) BEHAVIORS, FEEDS OFFSPRING CLASSIFY ESPECIES .

                       EXTINCTION OF SPECIES

ENVIROMENT CHANGES PRODUCINGFEWER AND FEWER OFFSPRING CLIMATE BECAME WARMER FOOD SUPPLY DIMINISHED THEY WERE HUMNTED BY EARLY HUMANS. WOOLLY MAMMOTH TUNDRA MAMMOTH BONES AND FROZEN CARCASES WERE NOT AS GIGANTIC AS ONCE BELIEVED. WERE HERBIVOROUS HAD FLAT MOLAR TEETH ATE ABOUTH 136 KILOGRAMS OF VEGETATION A DAY SURVIVE IN THE COLD. THREE LAYERS OF HAIRY FUR LAYER OF FAT 10 CENTIMETERS UNDER THEIR SKIN.

                        NATURAL SELECTION

LIVING ORGANIMS HAVE CERTAING CHARACTERISTICS THAT HELP THEAM TO LIVE REPRODUCE, AND ADAPT TO DIFERENT ENVIROMENT. IT HAS A LONG TONGUE WITH  WHICH IT                               CAN EXTRACT THE INSECT THAT ARE  FOUND  IN THE TREE. MAMMALS BONE HASCERTAIN DIFFERENCES.OVER TIME EACH LIMB DEVELOPED  A SPECIFIC FORM THAT ALLOWEDIT TO ADAPT TO SPECIFIC CONDITIONS.

HUMANS BEING BEGAN TO SELECT THE TYPE SPECIES OF PLANTS AND ANIMALS.SOON THESE PREDOMINATED AND PLANTS WITH SMALLER CORN COBS DISAPPEARED.

THE POPULATION OF THE GIRAFFE ANCESTORS HAD DIFFERENCES NOT ONLY IN THE  LENGTH OF THEIR NECKS BUT  ALSO  IN ODER  CHARACTERISTICS SUCH AS IN  SIZE AND WEIGHT. GIRAFFES THAT  SURVIVED HAD OFFSPRING WHOSE NECKS WERE LONGER ,AND THESE ANIMALS BECAME THE  DOMINANT SPECIES
