Report about the origin, characteristics, and

discoveries of the Homo Erectus and Callao Man

Homo Erectus

Homo Erectus

an extinct species of hominin that lived throughout most of the Pleistocene geological epoch.

Its earliest fossil evidence dates to 1.9 million years ago and the most recent to 70,000 years ago.

What is a Homo Erectus?

It is generally thought that H. erectus originated in Africa and spread from there, migrating throughout Eurasia as far as Georgia, India, Sri Lanka, China and Java. But other scientists posit that the species rose first, or separately, in Asia. (Wikipedia)

OriginThe first hypothesis of origin is that Homo erectus rose from the Australopithecina in East Africa sometime during—or perhaps even before—the Early Pleistocene geological epoch, which itself dates to 2.58 million years ago

The second hypothesis is that H. erectus evolved in Eurasia and then migrated to Africa. They occupied the Dmanisi site from 1.85 million to 1.77 million years ago, which was about the same time or slightly before their earliest evidence in Africa. There are several proposed explanations of the dispersal of H. erectus georgicus—including whether or not Africa is the source).

What is a Homo Erectus georgicus?

Homo erectus georgicus is the subspecies name assigned to fossil skulls and jaws found in Dmanisi, Georgia. First proposed as a separate species, it is now classified within H. erectus.

Tools usedEarly Homo erectus used comparatively primitive tools.

Let’s think and imagine if Homo Erectus still exist today.

Callao Man

Callao ManCallao man refers to fossilized remains discovered in Callao Cave, Peñablanca, Cagayan, Philippines in 2007 by Armand Salvador Mijares. Specifically, the find consisted of a single 61-millimeter metatarsal which, when dated using uranium series ablation, was found to be about 67,000 years old.

As of July 2010, the biological classification of Callao Man is uncertain. The metatarsal bone discovered has been identified as coming from a species of genus Homo, but the exact species classification is uncertain.

It has been speculated that Callao Man may be Homo sapiens or Homo floresiensis, though the latter is sometimes considered a pathological specimen of the former.Distinguishing between the two species would require material from the skull or mandible.As of 2012, the team that discovered the bone were seeking permission to search for more bones in the area.

The archaeologist also found deer and wild boar bones at the same layer of sediment where they found the bones of Callao man. The bones of the animals have cut marks but the archaeologists did not find any stone tools in that area.
