We Must be More Cynical of Human Evolution Theories

The history of human existence is a highly speculated and heated subject of debate. Many seek for origins of mankind through religious and cultural contexts. Although no definitive answer has been established, society often tends to look towards science for explanation of this mystery. Surprisingly, much of what is presented in regards to human evolution is taken as fact. There is an underlying de-emphasis on particulars such as hypothesis and theory. Rather than disillusionment resulting from constant discoveries which discredit previous beliefs, a reinterpretation is created and subsequently taken as truth. Although a great ...view middle of the document...

This can be viewed as directly contrasting the hypothesis that early human hominids came from Africa and spread to Eurasia. The skulls serve as evidence of primary evolution in Africa then proceeded by a migration to Eurasia3[3]. In addition, scientists tracking evolution through analysis of change in mitochondrial DNA (mother to daughter) help discredit previous notions. They estimate lineage in Africa to what has been dubbed “Eve” around 150,000 years ago which is the exact time period the Herto skulls are believed to be from4[4].

Now before continuing mentally digesting new contradictions in evolutionary theory, one must consider how much stock to place in these new discoveries. The Herto skulls pre-date most Neanderthals, key word being most and not all. Explanation for the exceptions is unaddressed and consequently makes subscribing to new views difficult. Logically, if there is an exception of a statement, then the statement can not be true. Also, proof that we do not descend from Neanderthals does not necessarily prove unequivocally that we come from the Herto species dubbed idaltu either5[5]. The skulls also provide support for a particular migration theory, key word being theory. But as aforementioned, once some new discovery discredits the inferences of the previous, a reinterpretation, not necessarily proven, will be accepted as common truth until the next. The fact that the new discoveries still only lead to mere theories as opposed to definite evidence becomes irrelevant via excitement and sensationalism of new findings.

One rationalized justification now being used to contradict previous theories is the human fossil record. The Herto skulls fits a time frame that fulfills a now fixed gap of lacking intermediate fossils between pre and modern humans (between 100,000-300,000 years ago)6[6]. Be reminded and take into account that there will always be a gap to fill as long as new discoveries are made. Attention is also drawn to previous fossil findings as being younger in age, scattered site-wise, poorly dated, and incomplete7[7]. This implies that the Herto skulls are of better quality while not appearing to share Neanderthal and Erectus characteristics found in the earlier “unsatisfactory” discoveries. These details may be true but are not substantial enough to qualify as evidence to sufficiently prove or disprove ancestry. Technological advances of the future will certainly make current findings able to be judged as scattered and incomplete.

Upon comparison to other fossils, similarities are also now being used as evidence for speculation. The skulls less prominent brow ridges and higher cranial vault8[8] differentiates them from pre-humans and, through process of elimination, links them to modern humans. The Herto skulls are also linked by observed similarity found in some Australian and Oceanic individuals in terms of morphology (branch of biology that deals with the form and structure of organisms)...
