EVOLUTION OF BIRDS

EVOLUTION OF BIRDS

We think that birds evolved from flying dinosaurs that lived in china during the early Cretaceous period,this is wrong.This dinosaurs disappeared 65mya,so how they evolved?The story starts back in the Jurassic with a creature called Ornitholestes,a 2m carnivore that that hunt lizards and mammals and scavenge on eggs.But he have something,the reason that is the ancestor of all birds.His hands are crushed,like all birds today when they landed.His hands became more crushed and at the behind side of them,feathers have evolved for the first time in dinosaurs.In their shadows the gliding dinosaurs evolved but they will vanish.65.5mya:All around the world small theropod dinosaurs have evolved,like Deinonychus in N.America,Velociraptors in Mongolia and the most related to birds,the Alaskan Troodons in Alaska.All of them have feathers and with their large brains they survived the extinction to come and leave behind the small bird like dinosaurs that lived only in China.But right after the dinosaurs they didn’t evolved to modern birds,to 2-3m tall birds that can’t fly but ruled the Earth,the 2m tall birds called Gastornis evolved finally to modern birds from lose size and their wing’s suffuse.But this birds rule every continent except S.America,a very alone and have unique animals continent.Here 3m tall terror birds rule this continent until the saber tooth cats came from N.America and vanished them.Today the birds are as we see them,some are great aerial predators like the falcon,the eagle,scavengers like vulture,some of them live as great swimmers like the penguins or some of them can’t fly like the ostrich.The biggest wingspan is held by the Marabou Stork’s,is over 4m in wingspan and is live now on Africa,meny birds will come,some will can’t fly other may can fly,until as all creatures disappeared.

THE K-T EXTINCTION

THE END OF THE DINOSAURS

165.5mya:At the asteroid belt between Jupiter and Mars billions of rocks are going to the same direction,all except this one which moves at 22.000 miles per hour,he smash in another asteroid bigger than it and resulted to millions of debris,but this ruin have the ability to change history,because it head on for the 5^th largest planet in the solar system,the only planet known to entertain life,planet Earth.65.5mya:The Earth now is rule by dinosaurs,the climate is wet and hotter than today.Reptiles are live everywhere,on land,in the air,and even in the oceans.It’s a paradise,but is in the brink of extinction.A quarter of a million miles up is the planet’s last hope of defense,the moon has saved the planet before,it’s full with craters made by collisions with small asteroids.But the moon isn’t at the right place at the right time,nothing can stop the asteroid now.The asteroid is 6 miles across and weight over 2 trillion tones,as it coming closer the gravity of Earth pull it and speed it from 40 to 45.000 miles per hour,the last day is here.It smash on the swallow waters of the gulf of Mexico.At impact,rocks the size of buildings exploding in the air,but what goes up,must come down.A rain of rocks is hit America and Mexico.At the other side of the planet,Mongolia is 8.000 miles from ground zero,and yet catastrophe hasn’t seen.In the time of 5 minutes,many dinosaur species are already extinct,and yet the worst hasn’t came.A fireball rises above ground zero over 100 miles up 70 billion tones of stone and Earth field the upper atmosphere with a cloud of microscopic dust and glass,and it’s spreading,fast.This is the ejectorcloud,this cloud is over 15.000 degree cloud destroy everything in it way,it hits every second more and more lighting strikes hit the surface and create fires and make the cloud,a electrical storm.The cloud riches Mongolia and superheated the ground,at 100^oC C  the only hope is hiding,at 160^oC the survival takes minutes,at 200^oC just secononds.1 hour and 30 minutes after impact the temperature at the ground of Mongolia riches 300^oC,you can’t breathe at that heat.There are a few places to stand and almost anything to eat,many species are already extinct.In Mongolia the temperatures are droping.The ejectorclud begins to clear but he done abnormalities in the weather system,in Mongolia sand storm take over action.Mongolian sand storms cover much of the continent of Asia.Across the whole planet herbivores search for food despite there isn’t,for the carnivores,life is easier because they are scavenging in carcass or hunt the existed herbivores.Deep benith the waves,the 11,1 richter earthquakes make tsunamis over 100m tall and cover 40% of land.But is something yet to come,1 million mega-tones of energy slammed in to the Earth,shockwaves create faults and pull molten rock in to the surface and created volcanic activity that took to the air poisonous gasses,the tectonic plates elsewhere from their positions and surrounding it with rain clouds,asset rain clouds until the sunlight and warmth can’t rich the planet’s surface and turn the climate more and more cold.All the dinosaurs that survived the physical catastrophes,are now enemies of them shelf’s.All around the world small pieces of dinosaurs try to start all over again,but they need population,and they don’t have it,without population they just as all species did without population,disappeared.At the end of the extinction that called K-T extinction,K-T means Creatceous-Tertiary [the next time period],70% of life on our planet perished.Dinosaurs[almost],aquatic reptiles and flying reptiles called Pterosaurs they all disappeared,but our ancestors the early mammals survived and replaced them.But dinosaurs exist as the most notorious monsters of the planet.All because they died can human being live.

HUMANITY'S EVOLUTION

EVOLUTION OF HUMANS

3.5mya:Our ancestors,the Australopithecus are live in Africa,they are unique,because they do something that no other ape has ever do,they stand and walk on 2 legs and they are 1m tall,but why?The answer is because the Himalayas have just been created in Asia,they create monsoons and they go to Africa,but they aren’t wet,they are dry.So the rain forests retreat and they become the savanna,so our ancestors must come down from the trees and search for food on their own on 2 legs.2mya:At that time our ancestors are called Homo Habilis,they are 1,5m tall and very special,they are scavengers,unlike no other ape.The flesh that they ate has proteins that use for have bigger,and they start to work as a team,sociality.1.5mya:Our ancestor now lives in Southern Africa,is called Homo Augusta,they are 1.6m tall and thtey have huge brains.They make friends and did the first dialogue and start to move out of Africa,they follow the Nile until middle east,this epic journey lasts for thousand years,in the eastern China they fed on bamboo and worms.They go so far that they change the name of the kind Homo Erectus.0.5mya:We go 1 million years forward but our ancestors haven’t go forward,but they create something that no animal has create before,fire.And now they control their world.Some hundred years later,the only thing that is missing,is imagination.The reason that we ave imagination is the weather,our ancestors return in Africa and go to Europe,but to the north it’s an ice age and in the south,a drought.140 thousand years ago:At Europe the Neanderthals adapt with short height,only 1.5m tall,noses to cool them down if they want and are very tough,but they don’t have imagination,their tough is enough to survive the ice age,but they will disappear,so they aren’t our ancestors,but what happened to them in Africa?Our ancestors there are on the brink of extinction.But they have something that makes them unique from any other creature in the 3.5 billion year story of life,imagination.But how we know it,we know from fossil ostrich eggs that have inside water,so our prehistoric family can drink water when she returns here in this drought world.They will pass many years until the weather changes again,110 thousand years ago the ice age melt out and water returns in Africa.30tya:A tiny group of survivors passed the ice age and start to multiply.For the first time our ancestors create languages and continue to sprawl across the globe,they create a kind of pains and when they migrate they left behind shines of their civilization in the rock.Soon they will be only one species of biped ape left on the planet,now the travel to the moon or the computer creating is just a question of time.And here our story ends.

EVOLUTION OF FLYING REPTILES

EVOLUTION OF FLYING REPTILES

-230mya[million years ago]:At this time some lizards want to catch their food,flies.But this lizards will fly after thousands of generations will be a group of reptiles called pterosaurs [flying lizards].We can see the brigde between pterosaurs and lizards in an animal today,the Draco.It too eat flies it had to fly.So it thrashing a small mattress of skin and live the ground he can’t fly but glide,the key of our story was lived 30my later in a very tropic world.-200mya:It’s named Dimofodon,it glides to catch insects and be safe from the early dinosaurs down that going to demeaned the world.-150mya:In China lives a monster,Darwinopterus.It’s a pterosaur that didn’t ate just insects,but small dinosaurs with it’s size.They evolved the winds but with a cost.They can’t walk quick on the ground in 4 legs,so they had to change the shape of their body.-140mya:All the pterosaurs before this time had long tales but now they became much shorter to walk better in the ground.-80mya:At that time the pterosaurs with short tales demeaned the skies,one species that ate fish is the most demeaned and big is Pteranodon,6m wingspan.But how so giant creatures can fly?The answer is on a fossil Pteranodon bone,it’s hollow.Birds and pterosaurs lay eggs but the pterosaurs born with the ability to fly,and this help some some creatures to get gigantic.-65.5mya:With 5 times better saw,a wingspan of 15m and a weight of just 2 humans Quetzalcoatlus is the largest creature ever to flew.They fed in flesh of dead dinosaurs and had hollow bones to fly.During the late Cretaceous period was lived in Mexico.But after so much success they vanished by the asteroid strike that vanished dinosaurs,aquatic and flying reptiles,including, Pterosaurs.
