As scientists have been putting this picture together, one irony is that Cro-Magnons had black skin, and Neanderthals might have had light hair and eyes, as an adaptation to the cold climates that they lived in, as with Europeans today. It turns the racist aspect of on its head, and has been noted in some scientific corners. For the remainder of this essay, as all other human species were extinct but for the “hobbits” by 30 kya, the word “human” will refer to behaviorally modern .

About 30-27 kya, after Neanderthals made their final exit, the only other humans on Earth were “,” hiding in their refugia. They disappeared around when behaviorally modern humans arrived, too. For the “hobbits,” a volcanic explanation has been proffered for their extinction, although they probably coexisted with modern humans. A problem I have noticed with the arguments of human-agency skeptics is that the fossil and archeological record is currently too thin and the dates too equivocal to confidently place closely occurring events in sequence and establish causal relationships that precludes human influence. In all such extinctions, I have seen no convincing arguments and evidence that rules out the involvement of


SparkNotes: Beowulf: Character List

Social cohesion was not only attained by the benefits of social interactions, but also by punishments when freeloaders did not pull their economic weight in a society. Scientists have developed a concept called that is not altruistic (giving without an expectation of individual gain) at all, but more of a societal accounting concept. Universal cooperation is seen as good for all of society’s members, and acts of “altruism” will eventually be “reciprocated” by some member of the society, if not the member initially helped. A trait of UP is ensuring that and that cheaters are punished. The carrots and sticks of rewards and punishments are probably as old as the earliest social animals, but as with all areas like this, humans have achieved the most sophisticated behaviors.

The Andamans are members of a racial group called , which appear to be remnant populations of the original migration from Africa. They all survived in marginal environments where they subsisted as hunter-gatherers, while later agricultural immigrants dominated arable lands. About 50 kya, a few thousand years before the migration to Australia happened, the sea level was lower and the islands of , , and formed a contiguous peninsula today called . , Australia, and were also connected and formed a continent today called . Deep water lay between those two “lost continents,” and biologists drew lines between them that noted the distribution of animals and plants that did not cross open water. is farthest north, followed by , and is farthest south. Those lines mark the limits of migrations from Sundaland toward Sahul, which followed sea level changes. About 48-46 kya, behaviorally modern humans crossed the water in boats to Sahul, and the peoples of New Guinea, Australia, and Tasmania largely lived in isolation until Europeans arrived. Those peoples have remnants in their DNA, which probably means that they interbred with them while driving them to extinction on Sundaland and Southeast Asia, before some migrated to Sahul. Aboriginal Australian isolation was almost certainly maintained in the way that Andaman Islanders did it: by killing strange peoples who came ashore. However, in 2012, a paper was published regarding evidence of contact about four kya with people probably from India, when the , , and some Indian DNA admixture were introduced into Australia, which seems related to a colonization of northern Australia by an immigrant population. More of those kinds of migrations of human DNA, technology, and domesticated species have yet to be discovered, and some may even be significant.

As scientific investigations deal with the human line, the issues increasingly become more complex and difficult to untangle and assess. This is largely because of human consciousness, which is a wild card, something that if not different in kind, is vastly different in degree, at least for land animals; . Designing falsifiable hypotheses for testing human behavior and consciousness has provided challenges not seen in other sciences, and experiments performed on our primate cousins have also become more humane. Dissecting chimp brains while they are still alive is as ethically unacceptable today as doing it to humans. Even today, data on the effects of cold and altitude on humans was primarily gleaned from . Today’s scientists who study human consciousness and its relationship to physical reality have been limited by ethics and what is perhaps the primary limitation: in studying human consciousness, scientists are studying themselves. The ideal of objective examination of the material world is hampered by , and an objective examination of human consciousness, by , may well be an impossible goal.

Chapter 7: HUMAN SOCIETY - Project 2061

Although our species, (named if we consider that Neanderthals and an are subspecies of but I will use in this essay to denote today’s humans), is the only survivor of the past several million years of human-line evolution, many of our cousins and ancestors were recognizably human. When did language begin, especially spoken language? Language certainly predated the appearance of . All great apes readily learn sign language, and even when monkeys chatter, the , and there is plenty of evidence that great ape vocalizations can . The and their corvid cousins can be hard to believe; they can solve some problems better than great apes can, and birds do not have a neocortex, but seems to function like the neocortex does. Becoming that began to . If fossils are sufficiently preserved, important anatomical features can provide key evidence for human abilities and behaviors. Turkana Boy, for instance, had his inner ear, which is responsible for balance, preserved well enough so that it provided more evidence that he did not spend time in trees (it is larger in primates that regularly climb). Similarly, the , which succeeded , apparently enabled keener hearing than its predecessors were capable of, and may have reflected the beginnings of spoken language. There is strong evidence that . As with many other human traits, the potential for language seems to have existed with monkeys (), and it kept developing more sophistication over vast stretches of time, and structural and cognitive changes interacted as human language developed into today’s version.

Chapter 11: COMMON THEMES - Project 2061

About a quarter-million years after Oldowan culture began, a new species appeared called , named by Louis Leakey in 1964. Whether is really the first member of the human genus has been debated ever since. As with all of its primate ancestors, was adapted for tree climbing. Virtually , especially those in Africa. Silverback gorillas are about the lone exception, along with some isolated chimps. certainly slept in trees. The predators of African woodlands and grasslands have been formidable for millions of years, and predators of in those days included , , and . Night camera footage is readily available on the Internet today showing the nighttime behaviors engaged in by hyenas, lions, and others. The African woodlands and plains are extremely dangerous at night, just from roving predators, not to mention being stumbled into by elephants, rhinos, and water buffalos. Today’s African hunter-gatherers sleep around the campfire to keep predators and interlopers at bay; a sentinel keeps watch as everybody sleeps in shifts through the twelve-hour nights. They are safer from predation at night in camp than they are in daytime as they roam.
