  Evolution of Modern Humans:  Early Modern Homo sapiens
It would seem from these dates that the location of initial modern Homo sapiens evolution and the direction of their dispersion from that area is obvious.
David Frayer, of the University of Kansas, believes that a number of European fossils from the last 50,000 years have characteristics that are the result of archaic and modern Homo sapiens interbreeding.
It was a partial skeleton of a 15-16 year old male Homo sapiens who lived about 30,000 years ago or a bit earlier.

Homo sapiens is the first species to understand its own origins and, in doing so, is now able to see dimly its own future and consider manipulating it directly by adjusting its own genome.
There are limits to Homo Sapiens, limits to the environmental stress planet earth can withstand, and as a species we may be close to extinction, to be replaced by a whole range of silicon life forms.

Homo neanderthalensis, Homo erectus) were also adept tool makers and there is some evidence that they may have had linguistic skills.
While humans have all these characteristics, from the biological viewpoint the question "What single characteristic distinguishes humans from all other animals?" is an odd one: it is not a question that is usually asked of cats, dolphins, or song sparrows.

The Common Chimpanzee (Pan troglodytes) and Bonobo (Pan paniscus) are sometimes grouped in the genus homo by biologists.
It is an interesting fact that Linnaeus, who first grouped the chimpanzee (only one species was known at the time) in a different genus than Humans, later regretted this (in his view) artificial division.

 The African Replacement Model and Multi-Regional Model of Human Evolution
There was, however, gene flow between Homo sapien populations during their evolution, thereby preserving the continuity of the species.
However, the archeological record does not appear to show that Homo sapiens had any technological advantage, and there is no evidence of abrupt technological changes in Europe, as may be predicated by the African replacement model.
For example, the one-million-year-old Homo erectus fossils found in Java have a prominent browridge — a distinctive characteristic of their modern contemporaries, such as the Australian aborigines (it is believed that their ancestors left Java for Australia approximately 60,000 years ago).

This is the bioenergetic context in which Homo sapiens evolved, and it accounts for both the wild growth of human population and its imminent collapse.
Homo habilis and his fellows were furtive little scavengers who picked what they could from carcasses that leopards left behind and rounded out their diet with fruits and nuts and roots (see Binford, 1981; Brain, 1981).

The various species that were involved in the evolution of man over the last 5 to 8 million years may be extinct in the sense that today no living purebred examples exist, but the genetic code of those species is almost completely intact.
It now seems highly likely that Homo sapiens and Homo neanderthalensis never interbred and that Homo sapiens had marginal competitive advantages that caused a slow decline in Neanderthal populations over a period of about 20,000 years that ended in their extinction some 30 KYA.

We hear of the evolution of TB for example to a point where drugs that use to be effective now are not because the organism has evolved to a organism that is no longer effected.
However, when it comes to the evolution of Homo sapiens and other higher plants and animals, though the evidence seems clear as to how these organisms evolved, science never lists anything as fact unless it can be clear demonstrated.
The evolution of higher organisms is a theory, because the facts are not available to be absolutely sure, but there is a growing amount of facts that clearly suggest that evolution of all living things did occur.

Because of the overlapping of some of these dating periods, the beginning location of the evolution of modern humans from archaic Homo sapiens is unclear.
The abruptness of the appearance of Homo sapiens sapiens in Europe, 50,000 years ago, can be accounted for by their migration into the region from another area, possibly Southwest Asia or North Africa, and the interbreeding that may have occurred with the Neandertals they shared the area with for another 10,000 years or more.

 Evolutionary Threads
Because evolution arises from the ostensibly random entropic nature of mutation itself, it is one of the fundamental processes creating order from disorder, utilizing the incoming free-energy of the Sun's radiation to form an open, far-from-equilibrium system at the edge of chaos.
Evolution as a process is a combination of opportunistic mutational change and selective advantage in an overwhelming sea of deleterious accidents, forming a creeping doorway.
It may even be that evolution is a complemenataion between fundamental bifurcations of type, such as that between the proterstomes and deuterostomes and the more accidental adventitious aspects of evolution which have resulted in the unusual alkaloids such as vincristine found in individual species.

Note, however, that the extinct species of the Homo genus (eg, Homo neanderthalensis, Homo erectus) were also adept tool users and there is some evidence that they may have had linguistic skills.
While humans have all these characteristics, from the biological viewpoint "what distinguishes humans from all other animals?" is an odd question: there's no one thing that makes cats, dolphins, or song sparrows unique.
