WHO ARE MINE AND YOUR ANCESTORS

OUR EVOLUTION

-530mya:In the beginning we were small fish,2-5cm long called Haikuichthys,the first vertebrate and fish.Anomalacaris is the king of the Cambrian oceans because he have eyes which help him find food,including our ancestors.They must adapted or died,evolution takes over.Over millions of years fish built on their basing design,the muscles around their back bone evolved to a powerful tale and fins appeared,they evolved a big heavy head with the first complex brains.

-418mya:In this seas many creatures would be familiar today,the Orthocone is a relative of squid and octopus but is as long as a truck.Cephalaspis are 0,5m long and weight 25kg and our ancestor they are fish and targets to many predators,like Brontoscorpio and Pterygotus,the titans of sea scorpions or Eurypterids.The Cephalaspis are easy targets so evolution start to give them weapons.After millions of years passed their gills adapt to formed the first jaws with the very first teeth,some bones in their fins expand which became the first lims,this is where our arms and legs began,with 4 legs they can go out of the water on to dry land.

-360mya:Our ancestors now are the first amphibians,Hynerpiton are 1,5m long and 50kg in weight,to live on land they evolved simple lungs.Arthropod enemies still exists but they are the food.But now the fish are our ancestor’s enemies,primitive sharks are evolving,but even sharks are prey,Hyneria weights 2 tones,is 5m long and the king of the Devonian oceans.Despite they live on land,they lay their eggs in the water because the juveniles have gills,not lungs and the eggs are soft for the tough rocks of the land,the key to their future success lies in changing their eggs.They evolved a hard egg shell which protects the young in the inside from the drying sun.

-300mya:They are the first reptiles.But as they moved on land they face other giants,more deadlier than ever before,the arthropods are back.Petrolakosaurus  is a 0,5m long lizard,our ancestor for this time,he evolved a complex heart which help him to go away from his predators,like Mesothelea spider,Arthropleura and carnivorous amphibians.Here nothing is as it seens,the 50m tall giants may look like trees,but they are actually relatives of ferns.Meganura is a monster dragonfly with a wingspan of 1m,the king of the Carboniferous skies.But troubles blowing,a mega-storm will destroy the forests that had 10% more oxygen and wiped out all the arthropod killers,the reptiles survived and evolved.A huge sail thrashes from their backs to help them cool and warm whenever they want.-280mya:But now they rule the land.Dimetrodon is a vicious carnivore.It fed on Edafosaurus,a 3,5m long,hippo size and weight around 500kg.Dimetrodon lay eggs and the females protect them,they belong to a strange type of reptiles called,mammal like reptiles and 220 million years ago they split on mammals and reptiles.But unlike their mammal descendants they live their young after hatched and ate the weak ones to help the strong and their kind to survive.And now this reptiles evolved to get and rule every continent.Their legs strengthen and lengthen,holding them more up right and giving them speed.The sail from their backs disappeared and they even start to look like mammals,to house a larger brain,their skull bones expand in to an huge head,out of their jaws thrash huge sharp teeth and their muscles get stronger.

-250mya:But after 280 million years of evolution the war it’s much more than a battle between predator and prey,the whole planet is entering a mass extinction that will wiped out 95% of life on earth,at that time our ancestors are tiny,underground,0,5m long creatures called Diictodon,they will survive the extinction by hide in their burrows and fed on plant tubes,at the outside world 5m long monsters called Gorgonopsid hunt on 5m long armor herbivores called Scutosaurus.From little Diictodon larger,stronger herbivores evolved.

-248mya:Lystrosaurus are 2m long 100kg weight beasts that are the ‘’bridge that will break’’ at mammals and reptiles.They aren’t social but in 246 million years they will be our ape-mans ancestors.If they survived they dinosaur age.
