The form of the Homo erectus cranium

Having thickened cranial vault bones, verso heavily built face, thick-boned jaws, and thick postcranial bones may have been necessary, or at least an advantage, for the body esatto cope with these long lifespans

Some creationists see environmental factors and genetic effects, such as the founder effect, genetic drift, and inbreeding, as most likely sufficient to explain the differences con skeletal features between modern humans and so-called cavemen. 37 It has been proposed that there was verso period of rapid human diversification beginning during the construction of Babel, resulting in extreme morphological variability in post-Babel humans repopulating the earth. 38,39 Other creationists believe the stark difference durante morphology between robust and anatomically modern humans warrants an explanation a dato che, that is, not just an acknowledgment that there was considerable variation per features, but why.

Per subject of importance sicuro the creation model is explaining why the skeletons, particularly the skulls, of humans such as Homo erectus (as well as those classified as Neandertals and Homo heidelbergensis), were so rugged or robust compared preciso anatomically modern humans

As such, it has been suggested that Homo erectus, Neandertals and the like all arose modo ‘devolution’ from anatomically modern post-Babel populations-from the genetic consequences of inbreeding, drift, and mutational effects, after splitting off from anatomically modern humans. 40 However, this would have onesto have happened independently, sopra verso relatively short time, sopra many different parts of the world, which seems verso little too coincidental onesto be realistic.

Along with verso number of other creationists who have contemplated this issue, I consider the robust human forms, such as those with the features observed con the typical Homo erectus and Neandertal remains, to sopra general be non-pathological. As such, they were likely humans that were part of the original dispersion that occurred at Babel. Hence, an explanation that is worth considering is that the robust morphology observed sopra these humans is linked onesto longevity. According preciso creationist Carl Wieland:

Hence, one explanation why humans such as Homo erectus, Homo heidelbergensis, and Neandertals, had different morphology compared puro modern humans, particularly sopra the skull, is that it could reflect changes mediante development of these early post-Flood individuals, compared esatto modern humans, possibly linked puro longevity. 42 A factor that cannot be ignored durante a creationist model of human origins is the biblical long lifespans of individuals mediante https://datingranking.net/it/meet-an-inmate-review/ the pre-Flood world, and onesto some extent the early post-Flood earth, as derived from Old Testament records. Per the pre-Flood world lifespans of around 900 years appear esatto have been common, and even individuals born early post-Flood (within a few hundred years of the Flood having occurred) are recorded as having lived for hundreds of years. 43,44

If initially (after the Fall) humans were designed onesto live for hundreds of years, then this would most likely have verso bearing on development processes and timings. Simply put, longevity would probably be associated with changes con development, not just the aging process.

If longevity was linked to development processes associated with the above-mentioned robusticity, then robust features would be expected sicuro disappear with shorter lifespans, although, as Wieland libretto, “some of the genes coding for some of their distinctive bony anatomy were apparently passed on onesto some of today’s populations”. 45 Hence, robust features do not correlate with the potential for longevity in recent times. A genetic mechanism for robusticity would possibly involve the control of hormones related esatto bone growth and maintenance. According preciso Susan Crockford, an evolutionary expert in this sezione, the

Thyroxine (T4) is an important thyroid hormone, and a un thyroid hormone secretion pattern could have existed mediante people with robust skeletal morphology, such as Homo erectus and the Neandertals, linked sicuro the genetic mechanism for long lifespans. Add environmental influences, as well as genetic effects such as genetic drift, and you can possibly account for differences in the many skeletal features observed. This would be not only between early robust post-Flood humans, like Homo erectus, Homo heidelbergensis, and the Neandertals, but also between anatomically modern humans and these early robust post-Flood humans.
