MAMMAL LIKE REPTILES:OUR STRANGE ANCESTORS

MAMMAL LIKE REPTILES

-300mya:Our lizard ancestors are evolving,a sail trashed from their backs give them the ability to cool and warm whenever they want.-280mya:The reptiles that evolved now are belong to the strangest type of animals ever existed,the mammal like reptiles,half mammal,half reptile.The first mammal like reptiles that evolved are Edafosaurus,a hippo size herbivore,they are 4m long and weight around 300kg.But they are prey,to Dimetrodon,a vicious carnivore,he evolved sharp teeth to cut the flesh of it’s prey.This is the reptilian characteristic,the mammal one is that she protect it’s eggs until hatched,then she kills the weak ones to give a chance of survived in the strong ones and her kind,she buried the eggs on a deep burrow then protect and give them the best temperature.and now they evolved to rule almost all the continents.The sail disappeared from their backs,their legs straighten and tey evolved bigger brains,but lose size.-250mya:Now 5m long carnivores with the first saber teeth rule the surface world,Gorgonopsians but our ancestors are the first creatures with ear bones,are 0,5m long and plant eaters,they called Diictodon.Scutosaurus are 4m long,they weight 1 tone and they are well armor,tis early reptiles are more closely to our ancestors,mammals than to lizards and crocodiles,they don’t have fair,but they evolved the glands that secrete their smell.But most of life will wipe out from volcanic activity in Siberia,95% of life is dead,Diictodon are the only survivors.From little Diictodon larger,stronger herbivores evolved.They rule the Earth for 70 million years,but then,they split in mammals and reptiles at the early Triassic era.They are our ancient ancestors,but what would happened if they don’t exist on the planet?
