Humans have partake stories about giants for thousands of years , from the cyclopes of Greek mythology to the biblical Goliath . But are these just grandiloquent tales , or have giant man really walked this Earth ?
If you weigh a nearly 9 - foot - grandiloquent human a giant , then yes . Robert Wadlow , the tall person on record , grew to 8 feet , 11 inches ( 2.72 meters ) before he died at the years of 22 in 1940 , according toGuinness World Records .
Robert Wadlow, the tallest man on record and real-life human giant, stands with actresses Maureen O’Sullivan and Ann Morris in 1938.
Wadlow was well above the currentU.S. average male heightof around 5 feet , 9 inches ( 1.75 m ) and even taller than some interpretations of thebiblical description of Goliath . Still , there was nothing magical about Wadlow . As with most actual - life giant , his height resulted from a aesculapian experimental condition .
" The absolute majority of [ hulk ] patient role have a growth hormone problem,“Márta Korbonits , an endocrinology professor at Queen Mary University of London , told Live Science . " That ’s what Robert Wadlow had . "
Korbonits noted that the leading causal agency of giantism is elevated levels of a emergence endocrine grow by the pituitary gland in the learning ability . Most of the time , these mellow levels are triggered by a benign neoplasm . One reason it ’s improbable we ’ll see another someone as marvelous as Wadlow again is that Dr. can nowremove the tumorand manipulation medications to arrest growth , as gigantism and the tumor endanger a soul ’s health .

Other atmospheric condition can cause the great unwashed to be extraordinarily tall . These let in Marfan syndrome , a inherited disorder that causes bones to grow longer , Korbonits explained .
However , some people maturate to uttermost acme without a known medical condition ; they include theformer earth ’s tallest humanity , Bao Xishun , who stomach 7 feet , 9 inches ( 2.36 molarity ) — a giant without giantism . They probably have a set of familial random variable that predispose them to tall stature , Korbonits said .
While it ’s easier for researchers to analyze giants living in modern times , extremely tall people have in all probability always been around . Theoldest know case of gigantismcomes from the alleged stiff of an ancient Egyptian pharaoh , who was around 6 animal foot , 1.6 column inch ( 1.87 m ) , while Korbonits’researchhas found that many real - lifeIrish giantsinherited a factor mutation from a soul who lived 2,500 year ago .
" Since human beings has been around , we ’ve had these disease , so there ’s no ground you would n’t have had these giants in Ancient Egypt or any other time of human history , " Korbonits say .
genetic science aggregate with environmental component , such as dieting in early life , todetermine height , with populations often growing tall over time with the progress of civilisation . However , it ’s not always a one-dimensional trend .
Pavel Grasgruber , a investigator at Masaryk University in Brno , Czech Republic , told Live Science that some virile skeletons from the previous phase of the mammoth - hunting Gravettian civilization , from about 29,000 years ago , stand out for their over-the-top height and even facilitate toinspire myths about giants . The tall of these seven skeletons , excavated in the Grimaldi cave system in Italy around the turn of the twentieth century , isestimatedto have stood 6 feet , 5 inches ( 1.96 m ) .

" Consider that at the time these skeleton were found , the standard for manful height in Europe was under 170 cm [ 5 feet , 7 inches ] ! " Grasgruber said in an email . " No wonder these mass must have seemed like ' giants ' to the scientists of the prison term . "
Researchers do n’t do it if the tall remains were representative of the Gravettian universe . Still , Grasgruber remark that magniloquent males were distinctive of the former Upper Paleolithic populations in France and the historical realm of Moravia ( modern - daytime Czech Republic ) , achieving tallness that modern industrial nations did not pass until the mid-20th century .
" The reason for this good physical condition of early Upper Paleolithic hunters was the low-down universe density and stack of plot in the form of mammoths and other large mammals , " Grasgruber said .
