Hunting Hypothesis
In paleoanthropology, the hunting hypothesis is the hypothesis that human evolution was primarily influenced by the activity of hunting for relatively large and fast animals, and that the activity of hunting distinguished human ancestors from other hominins. While it is undisputed that early humans were hunters, the importance of this fact for the final steps in the emergence of the genus ''Homo'' out of earlier australopithecines, with its bipedalism and production of stone tools (from about 2.5 million years ago), and eventually also control of fire (from about 1.5 million years ago), is emphasized in the "hunting hypothesis", and de-emphasized in scenarios that stress the omnivore status of humans as their recipe for success, and social interaction, including mating behaviour as essential in the emergence of language and culture. Advocates of the hunting hypothesis tend to believe that tool use and toolmaking essential to effective hunting were an extremely important p ...

Paleoanthropology
Paleoanthropology or paleo-anthropology is a branch of paleontology and anthropology which seeks to understand the early development of anatomically modern humans, a process known as hominization, through the reconstruction of evolutionary kinship lines within the family Hominidae, working from biological evidence (such as petrified skeletal remains, bone fragments, footprints) and cultural evidence (such as stone tools, artifacts, and settlement localities). The field draws from and combines primatology, paleontology, biological anthropology, and cultural anthropology. As technologies and methods advance, genetics plays an ever-increasing role, in particular to examine and compare DNA structure as a vital tool of research of the evolutionary kinship lines of related species and genera. Etymology The term paleoanthropology derives from Greek palaiós (παλαιός) "old, ancient", ánthrōpos (ἄνθρωπος) "man, human" and the suffix -logía (-λογία) "study of". Ho ...

Central African Republic
The Central African Republic (CAR; ; , RCA; , or , ) is a landlocked country in Central Africa. It is bordered by Chad to the north, Sudan to the northeast, South Sudan to the southeast, the DR Congo to the south, the Republic of the Congo to the southwest, and Cameroon to the west. The Central African Republic covers a land area of about . , it had an estimated population of around million. , the Central African Republic is the scene of a civil war, ongoing since 2012. Most of the Central African Republic consists of Sudano-Guinean savannas, but the country also includes a Sahelo- Sudanian zone in the north and an equatorial forest zone in the south. Two-thirds of the country is within the Ubangi River basin (which flows into the Congo), while the remaining third lies in the basin of the Chari, which flows into Lake Chad. What is today the Central African Republic has been inhabited for millennia; however, the country's current borders were established by ...

Game Drive System
The game drive system is a hunting strategy in which game are herded into confined or dangerous places where they can be more easily killed. It can also be used for animal capture as well as for hunting, such as for capturing mustangs. The use of the strategy dates back into prehistory. Once a site is identified or manipulated to be used as a game drive site, it may be repeatedly used over many years. Game drives In the Rocky Mountain National Park, for instance, there are archeological remains from about 3,850 and 3,400 B.C. of 42 low-walled stone structures or cairns, up to hundreds of feet in length, built for game drive systems. These slight walls served as devices that permitted hunters to direct or herd game animals—like bison, sheep, deer, or elk—toward men waiting with weapons. Up to twenty-five people may have been needed to execute the game drive. Hunters may have killed the animals using darts, atlatl, spear throwers, or spears tipped with stone projectile points. ...

Skink
Skinks are lizards belonging to the family Scincidae, a family in the infraorder Scincomorpha. With more than 1,500 described species across 100 different taxonomic genera, the family Scincidae is one of the most diverse families of lizards. Skinks are characterized by their smaller legs in comparison to typical lizards and are found in different habitats except arctic and subarctic regions. Description Skinks look like lizards of the family Lacertidae (sometimes called ''true lizards''), but most species of skinks have no pronounced neck and relatively small legs. Several genera (e.g., ''Typhlosaurus'') have no limbs at all. This is not true for all skinks, however, as some species such as the red-eyed crocodile skink have a head that is very distinguished from the body. These lizards also have legs that are relatively small proportional to their body size. Skinks' skulls are covered by substantial bony scales, usually matching up in shape and size, while overlapping. Other gen ...

Goanna
A goanna is any one of several species of lizards of the genus '' Varanus'' found in Australia and Southeast Asia. Around 70 species of ''Varanus'' are known, 25 of which are found in Australia. This varied group of carnivorous reptiles ranges greatly in size and fills several ecological niches. The goanna features prominently in Aboriginal mythology and Australian folklore. Being predatory lizards, goannas are often quite large, or at least bulky, with sharp teeth and claws. The largest is the perentie (''V. giganteus''), which can grow over in length. Not all goannas are so large; pygmy goannas may be smaller than the arm of an adult human. The smallest of these, the short-tailed monitor (''V. brevicauda''), reaches only in length. They survive on smaller prey, such as insects and mice. Goannas combine predatory and scavenging behaviours. They prey on any animal they can catch that is small enough to eat whole. They have been blamed by farmers for the death of sheep, tho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Martu People
The Martu (Mardu) are a grouping of several Aboriginal Australian peoples in the Western Desert cultural bloc. Name The Martu people were originally speakers of various Wati languages in the Western Desert dialect continuum whose identity coalesced after coming into increased contact with one another after the establishment of Jigalong. Since the 1980s the Martu term for person (''mardu'' meaning "one of us") has prevailed among the peoples at Jigalong, Wiluna, Punmu, Parnngurr and Kunawarritji. In 1974 Norman Tindale wrote that the term had been applied to several groups in this area, among them the Kartudjara, and had no tribal significance but simply denoted that the people there had undergone full initiation. Languages The Martu languages belong to the Wati subgroup of the Pama–Nyungan language family and are collectively called Martu Wangka, or "Martu Speak". Many Martu speak more than one language and for many, English is a common second language. Country Their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spear-thrower
A spear-thrower, spear-throwing lever or ''atlatl'' (pronounced or ; Nahuatl ''ahtlatl'' ) is a tool that uses leverage to achieve greater velocity in dart or javelin-throwing, and includes a bearing surface which allows the user to store energy during the throw. It may consist of a shaft with a cup or a spur at the end that supports and propels the butt of the spear. It's usually about as long as the user's arm or forearm. The user holds the spear-thrower in one hand, gripping near the end farthest from the cup. The user puts the butt end of the spear, or dart, in the cup, or grabs the spur with the end of the spear. The spear is much longer than the thrower. The user holds the spear parallel to the spear-thrower and going in the other direction. The user can hold the spear, with the index and thumb, with the same hand as the thrower, with the other fingers. The user reaches back with the spear pointed at the target. Then they make an overhand throwing motion with the thrower ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hunter-gatherer
A traditional hunter-gatherer or forager is a human living an ancestrally derived lifestyle in which most or all food is obtained by foraging, that is, by gathering food from local sources, especially edible wild plants but also insects, fungi, honey, or anything safe to eat, and/or by hunting game (pursuing and/or trapping and killing wild animals, including catching fish), roughly as most animal omnivores do. Hunter-gatherer societies stand in contrast to the more sedentary agricultural societies, which rely mainly on cultivating crops and raising domesticated animals for food production, although the boundaries between the two ways of living are not completely distinct. Hunting and gathering was humanity's original and most enduring successful competitive adaptation in the natural world, occupying at least 90 percent of human history. Following the invention of agriculture, hunter-gatherers who did not change were displaced or conquered by farming or pastoralist groups in ...

The Hunting Hypothesis
''The Hunting Hypothesis: A Personal Conclusion Concerning the Evolutionary Nature of Man'' (commonly known as ''The Hunting Hypothesis'') is a 1976 work of paleoanthropology by Robert Ardrey. It is the final book in his widely read Nature of Man Series, which also includes ''African Genesis'' (1961) and ''The Territorial Imperative'' (1966). The work deals with the ramifications of evolutionarily inherited traits in man, particularly those that developed through hunting. It was also one of the earliest books to warn about the possible dangers of climate change. Theories and controversy Ardrey's main focus in ''The Hunting Hypothesis'' was to examine the ways in which human evolution developed with and because of hunting behavior, and the effects on modern man of inherited traits related to this evolution.Ardrey, Robert.

Sexual Division Of Labor (evolutionary Perspective)
The sexual division of labour (SDL) is the delegation of different tasks between males and females. Among human foragers, males and females target different types of foods and share them with each other for a mutual or familial benefit. In some species, males and females eat slightly different foods, while in other species, males and females will routinely share food; but only in humans are these two attributes combined. The few remaining hunter-gatherer populations in the world serve as evolutionary models that can help explain the origin of the sexual division of labor. Many studies on the sexual division of labor have been conducted on hunter-gatherer populations, such as the Hadza, a hunter-gatherer population of Tanzania. Behavioral ecological perspective Man the hunter vs. woman the gatherer Both men and women have the option of investing resources either to provision children or to have additional offspring. According to life history theory males and females monitor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gathering Hypothesis
The gathering hypothesis is a term in evolutionary psychology coined in 1970s feminism as the antithesis of " hunting hypothesis", suggesting that gathering rather than hunting was the main factor in the emergence of anatomically modern humans. David Buss argues that tools were not used for hunting initially, but instead to dig up and gather plants. It is possible the invention of tools explains the transition from a forest habitat to the savanna woodlands and grasslands. Tools made gathering food easier and more economical enabling ancestral humans to live in a sparser environment. It was not until the invention of receptacles to store food that more elaborate tools used to hunt, skin, and butcher were developed. According to the gathering hypothesis hunting had no major role in the evolution of modern humans. One of the sources of evidence for the gathering hypothesis is in the alleged “Superior Spatial Memory of Women.” McBurney et al. found that women perform better on m ...
