The Origin of Anatomically Modern Humans
When and where did fully modern humans-what paleo-anthropologists call anatomically modern humans- originate?One hypothesis for the origin of fully modern humans is that Homo sapiens evolved in each region from the local populations of H. erectus. This model of parallel evolution of modern humans is called the multiregional hypothesis. It is mainly advocates of this hypothesis who refer to the regional derivatives of H. erectus as "archaic Homo sapiens," giving the geographic variants of fossils sub-species manes, such as H. sapiens neanderthalensis for European forms. In this view, the great genetic similarity of all modern people is the product ofoccasional interbreeding between neighboring populations that has provided corridors for gene flow throughout the geographic range of humans.
On the other side of a very lively debate about human origins are the proponents of the "Out of Africa" hypothesis, also called the replacement hypothesis. According to this hypothesis, all Homo sapiens throughout the world evolved from a second major migration out of Africa that occurred about 100,000 years ago- a migration of anatomically modern humans that completely replaced all the regional populations of Homo derived from the first hominid migrations of H. erectus out of Africa about 1.5 million years ago. Most advocates of the replacement hypothesis prefer to give separate species names to the regional hominids that were not anatomically modern, such as Homo neanderthalensis for the Neanderthals in Europe.
Note that both hypotheses recognize the fossil evidence for humanity's African origin. The debate centers on the vintage of the most recent hominid ancestor in Africa common to all the world's modern populations. The multiregional hypothesis places that last common ancestor in Africa over 1.5 million years ago, when H. erectus began migrating to other parts of the world. But accoring to the replacement hypothesis, the diverse human populations of the world are much more closely realated. In this view, all of the world's populations diverged from anatomically modern Homo sapiens that evolved from an African H. erectus population and then migrated throughout the world beginning only 100,000 years ago.[...]
This section deals with humans: I think it is clear why the multiregional hypothesis does not support genesis. It insists Adam and Eve must have lived at a point far earlier than modern humans to allow them to be the first common ancestor of humanity. This does not allow them to actually be human. So that hypothesis precludes genesis.
Look at the replacement hypothesis though; it suggests evolution from a previous ancestor to a form capable of replacing the global populations of other hominoids. Could that be the 'deeper meaning' (the golden apple) of Adam and Eve? Is the biblical version of genesis an account of the first human colony? I think not.
Dr. Schroeder makes abundantly clear that the changeover from 'genesis time' to 'human time' took place with the creation of the first man: Adam. If we ignore the supernatural origin of man's body (Gen. 2:7- And the LORD God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul), then we have the basis for a metaphorical interpretation. The underlined portion describes man's corporeal body while the bolded portion indicates the 'ensoulment' or creation of 'neshamah'. The importance of the latter half of the passage will become apparent soon.
Anatomically modern humans lived before 4,000 BCE- this much is indisputable. The best data source I have available to me is that the replacement postulated would have occurred about 100,000 years ago. This is much earlier than the changeover to 'human' described in Genesis. The implication is therefore that there must be some non physical difference between "Adam's" ancestors and himself- the neshamah- that manifested itself about 6,000 years ago, fulfilling both Biblical descriptions and scientific observations.
The 'neshamah' cannot be scientifically discussed- it is a matter of personal faith only. What can be scientifically discussed is the concrete facts around the time of the alleged 'neshamah's' creation and see if any difference manifests itself. Problems for Schroeder arise through this examination: there was a well organized state in Egypt before 6,000 years ago, and none of their records indicate a radical change in the nature or ability of Man (which would, of course, be a noteworthy event). In addition to the Ancient Egyptians' failure to notice a distinction between pre and post-Adam humanity, there is the plethora of earlier human activity.
Humans can be distinguished from other animals by certain behaviors:
[list]
[*]Humans have structured language- a definite grammatical structure and, occasionally, a writing system.
[*]Humans have the ability to create technologies to improve their standard of living and to improve those technologies- a beaver will not improve its dam by noticing flaws in the design. Even chimps (another species able to use simple tools) have not (to my knowledge) been observed to improve on the tools they use.
[*]Humans create art (music, dance and visual images). No other animal has been seen to create art.
[*]Often, humans formulate some sort of religion, while other animals have not been known to do so.[/list]
By these criteria then the 'non-human' predecessors to "Adam" would not have had a language or any form of art or religion. If they did then they would already have been human.
The problem is that organisms prior to 4,000 BCE did have those attributes- as suggested by archaeological evidence.
[list]
[*]The cave paintings in Pech Merle (France) are dated as old as 25,000 years before present- more than 4 times older than the Bible's 'humanity' is.
[*]Body adornments are seen as long as 35,000 years ago- almost six times older than Genesis's humanity. Bone needles have been found as early as 23,000 years ago.
[*]Pottery has been dated as old as 12-14 thousand years before present. This indicates that "prehumans" were able to build a kiln and get it to over 1000 degrees. Is there any non-human creature that can create pottery, let alone use it?
[*]Ancient communities about 8,000 years ago are seen to use seals, indicating some form of writing.
[*]Almost 2,000 years before the 'changeover' in genesis, Sumerian societies in Mesopotamia are creating temples! Is there any nonhuman creature that has an idea of religion?[/list]
The answer, of course, is no. "Human like animals" were displaying uniquely human behaviors long before the postulated 'final [spiritual] creation'. A contemporaneous society even fails to note any sort of change. There is no evidence whatsoever that any form of supernatural intervention made changes to society at that time, or even global society in the long run. Thus, the concept of a 'neshamah' defaults back into the area of pure faith.

The Biology of Human survival: life and death in extreme environments
[Although this discusses space colonization, the principles of genetics within a totally isolated community remain sound]
This means a permanent human colony in space [or the very first one- without neighbors] will have to be of sufficient size and genetic diversity to avoid random extinction. The minimum size necessary for a permanent, self propagating space colony has never been determined[...] If the limited genetic diversity of reconstituted populations of endangered species is any indication, the minimum founder population for a remote permanent space colony is likely to be on the order of 100 to 200 unrelated individuals.
A minimum viable population (MVP) size is an estimate of the number of individuals required for a high probability of survival of a population over a given period of time.Inbreeding depression refers to the reduction of genetic fitness within a population as a result of breeding between closely-related individuals.
Two people simply do not provide the requisite genetic diversity to populate the earth.
This is not, of course, an important point if you do not suggest a literal reading of the explanation of Man.
