Homo erectus: just a people group?
There has been ongoing discussion about the classification of
Homo erectus. Some researchers propose that it was a transitional species between apes and humans. Certain creation scientists previously
identified Homo erectus as an ape, though they now consider it fully Homo sapiens. “Many paleontologists and a majority of creationists
think their unusual features are nothing more than variants of human traits and not transitional at all.” [3]
As previously outlined
in the “Neanderthals: just a people group?” article, man is not an animal. Man has a superior brain not paralleled in the animal world,
possesses the faculty of speech, only is fully bipedal, and capable of expressing emotions superior to any animals.
Homo erectus Anatomy
· Distinct skulls
o massive brow ridges (supraorbital toruses) [4][5][6], thickens with age [7]
o low sloping forehead [8][9]
o “more constricted temples than typical humans” [10]
o virtually no difference in cranial morphology from Neanderthals, other
than brain size [11]
· Brain
o brain size
§ range averaged about 1050 ml [12]
§ averaged 1,000 ml in East Asia[13]
§ 545 - 775 ml in Dmanisi, Georgia [14]
+ size of brain may have resulted from pathological features of cretinism [15][16]
§ for
modern humans
+ around: male 1260 ml and female 1130 ml, “although there is substantial variation” [17]
+ ranges from about 800-2000ml[18]
o brain structure
§ “was similar to that of modern humans” [19]
· Jaw
o “large and thick without a pointed
chin” [20][21]
o “forward projecting jaw” [22][23]
· Teeth
o larger teeth than modern humans [24][25]
o “molar teeth had large roots” [26]
· Hyoid
o the only hyoid bone attributed to Homo erectus to date was found
at Castel di Guido (Rome, Italy). This “hyoid bone body shows the bar-shaped morphology characteristic of Homo, in contrast to the
bulla-shaped morphology of African apes and Australopithecus.” [27]
· Post-cranial Skeleton
o Turkana Boy ‘s
“post-cranial skeleton was essentially identical to modern humans” [28]
o “bones are extraordinarily thickened” [29]
o “East Asian Homo
erectus normally have more robust skeletons” [30]
o “human-like body proportions, with shorter arms and longer legs relative
to its torso.” [31]
· Height and Weight
o 4.8 - 5.4 ft in Dmanisi, Georgia [32]
o 4.8 - 5.5 ft, maybe
about 110 lb. [33]
· “[N]o H. erectus DNA has ever been found” [34]
Homo erectus intelligence, wisdom, and emotions
“From
what is now known of modern man, there is no relationship between cranial capacity and intelligence.” [35] [a] This insight challenges
earlier assumptions and highlights the complexity of cognitive abilities beyond physical brain size. Homo erectus, with its own unique
physical traits and cultural advancements, similarly prompts us to reconsider simplistic correlations between anatomy and intellect.
Homo
erectus exhibited remarkable achievements that reflect their cognitive and emotional complexity. Their cognition and/or emotions were
demonstrated by:
· The mastery of fire, as indicated by hearths and cooking, provided sustenance,
and enabled social interactions. Fire also offered warmth and helped in deterring large predators. [36]
· Their
ingenuity is evident in the crafting of Acheulean stone tools that revolutionized stone technology. [37] “Homo erectus had style and
design of tools down to a science.” [38] Also, “a great deal of skill was required to produce them.” [39]
o making hand axes that are
“pear shaped, teardrop shaped, or rounded in outline” by flaking “over at least part of the surface over each side (bifacial)” [40] These
hand axes were multi-purpose tools used for such purposes as “butchering and skinning game, digging in soil, and cutting wood or other
plant materials.’ [41]
o making picks and core axes [42]
· They made tools from the bones of “large animals
like hippos and elephants, and ... deliberately shaped them” to be “useful for butchering large carcasses.” [43]
o transferred flaking
skills from stone to bone, “which suggests a level of complex thinking.” [44]
o “knew about skeletal anatomy. They could identify
and select bones suitable for flaking.” [45] Flaking (knapping) “involves chipping away small flakes to create sharp edges.” [46]
· Fossil evidence, including Acheulean stone tools, suggests Homo erectus were efficient hunters. [47]
· It is
probable that Homo erectus employed clothing for reasons of modesty and protection against environmental elements, like contemporary
cultures. [b] Making clothes involves materials, visualization skills, and craftsmanship.
· Reasonable evidence
exists “that Homo erectus built boats and was capable of seafaring over moderate distances.” [48] The evidence includes ancient stone
tools of the types made by Homo erectus discovered in Crete, an island in the Aegean Sea that has never had a land bridge. Scholars
debate whether Homo erectus ever sailed to Crete since no Homo erectus bones have been discovered there. [49]
· Zigzag etchings on a shell by Homo erectus [50] indicate their potential communication or artistic abilities, highlighting their cognitive
skills. Art is associated with emotion.
Homo erectus was fully bipedal.
The Turkana Boy skeleton from
Kenya is the most complete Homo erectus (Homo ergaster?) skeleton found so far, with skeletal portions resembling modern humans. Its
“pelvis is narrower than in Homo sapiens, which is most likely for more efficient upright walking. This further indicates a fully
terrestrial bipedalism...” [52]
The femur of Homo erectus is the most frequently found non-cranial fossil, displaying significant similarities
to those of modern humans, barring the peculiar Trinil specimen. It is highly probable that Homo erectus demonstrated proficient bipedal
movement. [53]
“X-ray analysis of the semicircular canals of a number of apemen skulls showed that the Homo erectus canals were like
those of modern humans, meaning they walked upright” [54]
Was Homo erectus capable of language?
Although not all thought processes require
language, [55] the ability to articulate and hear language plays an important role in human communication. It is almost inconceivable
that people who are intelligent enough to master fire and make stone tools would not have utilized language. Language would have been
crucial for their social engagement, synchronization for hunting parties, and reaction to potential hazards.
A seafaring hypothesis
posits Homo erectus possessed the advanced communication abilities of language, which would be necessary to construct complex boats
and navigate maritime environments.
No evidence exists that Homo erectus evolved from animals or ever was without language. Those are
evolutionary assumptions only. The Bible (Genesis 1:26-27) states that God created man in His own image. God speaks to the first man
and woman (Genesis 1:28-29), the common ancestors of all mankind, so they must have had the ability to comprehend what He was saying.
In Genesis 2, Adam, the first man, was given the task of naming the various animal types and gave his verbal approval to his wife
Eve.
Conclusions
Homo erectus exhibited the unique features that separate man from animals including being intelligent and wise, having
faculty of speech, being fully bipedal, and possessing human emotions. Evidence does not suggest that they were transitional from
animals to man or that at any time they possessed the above features to a lesser degree than modern humans. Evidence does suggest
that Homo erectus was a group of ancient people from the same non-animal common ancestors as Neanderthals and modern humans.

Daniel Lyon, a guard for Pennsylvania Railway, had an adult cranial capacity of just 624 ml. Despite this, railway officials stated
that he could read and write and had no mental or physical defects. [56]

does not wear clothes. However, there are some places in the world where people do not wear clothes.” [57]
