In a previous post on Patagonian ogres and hairy giants, I suggested that this variety of Patagonian Bigfoot, might be a surviving Homo erectus, a direct ancestor of modern man (we are Homo sapiens).
Today I will look into this interesting subject. Interesting because, official orthodox archaeology does not believe that H. erectus ever reached America, and does not place modern man here earlier than some 20,000 years ago.
However, there is some controversial evidence (dismissed by mainstream archaeologists) that suggests an earlier peopling of America, roughly a quarter of a million years ago.
Recent survival of Homo erectus.
Homo erectus is an extinct species of humans that lived between 1,8 million years ago and at least 200,000 years ago (and probably even later than this last date). That is, during the Pleistocene Epoch. These hominids were intelligent creatures and manufactured stone tools, which we classify as belonging to the Acheulian culture. They were the first men to master fire. They were also explorers and were the first humans to break out of Africa, our birthplace and spread across the Old World.
Their remains have been found in Europe, Asia (as well as Africa). The oldest fossils are found in Africa, where they continued evolving into modern men. The African strain is different in comparison to the other H. erectus populations of the Old World and have been classed in a separate species named Homo ergaster. There is some debate whether H. ergaster or H. erectus is our direct ancestor.
Their use of a novel stone tool technology and fire, made them successful in spreading around the Old World and occupying different environments.
This may have been due to their larger brain size in comparison to our other older and more primitive ancestors. Their cranial capacities ranged from between 700 cm3 to 1,250 cm3, averaging 900 cm3. Their skulls had a thick cranial bone and large browridges over their eyes. Their braincase was long and low, with a receeding forehead.
They were not small like their ancestors, an adult H. erectus could weigh over 45 kg (100 lb) and measure 1,67 m (5 ft. 6 in).
Fossils of H. erectus found at Ngandong, Java, have been dated to as recently as 53,000 to 27,000 years ago. These dates were obtained by Carl Swisher of the Berkeley Geochronology Center and colleagues. . This is interesting because, it indicates an overlapping with modern man who arrived in that area roughly some 40 to 50 thousand years ago. So, if they managed to get to America, they could have also overlapped with modern man during some 20 to 30,000 years (which, would mean that they may have survived until a relatively recent date, or even still be alive somewhere out there).
During the late 1960s, at a site close to Mexico City, Mexico, named Valsequillo Reservoir, in the State of Puebla, some geologists of the United States Geology Survey (USGS) dated possible hominid remains as being 250,000 years old!. The team was led by archaeologist Cynthia Irving-Williams, and the results were published in a reputable scientific journal in 1969  but were quickly dismissed by mainstream archaeologists as being ridiculously old (nearly ten times the accepted dates for human presence in America - the Clovis First theory).

These remains are part of a:
"rapidly growing dating evidence from fission- track, U-series, diatoms extinct by the end of the Last Interglacial Stage (Sangamonian), etc. for (pre-Wisconsinan) humans in America (>80,000 yr BP), which has been ignored or denied by members of the American archaeological establishment " . 
So, they may be modern human (i.e. Homo sapiens) remains that predate the orthodox time-frame of some 20,000 years for human arrival to America.
Other ancient remains of stone tools have been found at Calico  in California, US at around the same time. They have been dismissed by mainstream archaeology as natural (not human) artifacts.
As far as I am concerned, the case remains open and undefined. The evidence is interesting and definitively points to an early peopling of America.
H. erectus had the brains and the physical aptitude to trek from China (his known northernmost habitat) to America through Beringia, just like modern man would do later. He could also have rowed along the coastal waters of Asia, Beringia and America all the way down to Southern Chile.
Lack of interest and funding (specially in South America, where research is restricted due to lack of governmental or private support) to look into these non-conventional ideas may delay the final proof, but it will surely be unearthed in the near future.
Impact on cryptozoology. Leaving aside Bigfoot for my North American colleagues, as it is not a Patagonian "monster", the presence of H. erectus could account for many native Patagonian myths regarding "ogres" or "man slaying" primitive men, it can also explain the "wild-men" legends and some "hairy" or "ape-like" creatures reported in Patagonia.
