Evolution Before about it was widely thought that distinctively hominin fossils could be identified from 14 to 12 million years ago mya. However, during the s geneticists introduced the use of molecular clocks to calculate how long species had been separated from a common ancestor. The molecular clock concept is based on an assumed regularity in the accumulation of tiny changes in the genetic codes of humans and other organisms. Use of this concept, together with a reanalysis of the fossil record, moved the estimated time of the evolutionary split between apes and human ancestors forward to as recently as about 5 mya. Since then the molecular data and a steady trickle of new hominin fossil finds have pushed the earliest putative hominin ancestry back in time somewhat, to perhaps 8—6 mya. Possible pathways in the evolution of the human lineage. Announced in , this specimen is dated to the period between 7 and 6 mya. The distinctive mark of Hominini is generally taken to be upright land locomotion on two legs terrestrial bipedalism. The skull of S.
Scientific dating has confirmed the long residence of Aboriginal people in Australia. A number of methods are used, all of which have their advantages, limitations and level of accuracy. Complex dating problems often use a variety of techniques and information to arrive at the best answer. Artefacts and other materials can be dated in relative terms by observing which layer of sediments they are found in.

Reviews 70 years of studies of climate forcing on fluvio-lacustrine systems in the Riverine Plain. Abstract Climatic forcing of fluvial systems has been a pre-occupation of geomorphological studies in Australia since the s. In the Riverine Plain, southeastern Australia, the stable tectonic setting and absence of glaciation have combined to produce sediment loads that are amongst the lowest in the world.
The region includes the Willandra Lakes, whose distinctive lunette lakes preserve a history of water-level variations and ecological change that is the cornerstone of Australian Quaternary chronostratigraphy. The lunette sediments also contain an ancient record of human occupation that includes the earliest human fossils yet found on the Australian continent.
To date, the lake-level and palaeochannel records in the Lachlan-Willandra system have not been fully integrated, making it difficult to establish the regional significance of hydrological change. Here, we compare the Willandra Lakes environmental record with the morphology and location of fluvial systems in the lower Lachlan. An ancient channel belt of the Lachlan, Willandra Creek, acted as the main feeder channel to Willandra Lakes before channel avulsion caused the lakes to dry out in the late Pleistocene.
Electromagnetic surveys, geomorphological and sedimentary evidence are used to reconstruct the evolution of the first new channel belt following the avulsion. Single grain optical dating of floodplain sediments indicates that sedimentation in the new Middle Billabong Palaeochannel had commenced before A second avulsion shifted its upper reaches to the location of the present Lachlan River by The timing of these events is consistent with palaeohydrological records reconstructed from Willandra Lakes and with the record of palaeochannels on the Lachlan River upstream.

C dating of otoliths provided highly precise results for human presence. Abstract Fish otoliths from the Willandra Lakes Region World Heritage Area south-western New South Wales, Australia have been analysed for oxygen isotopes and trace elements using in situ techniques, and dated by radiocarbon. The study focused on the lunettes of Lake Mungo, an overflow lake that only filled during flooding events and emptied by evaporation, and Lake Mulurulu, which was part of the running Willandra Creek system.
Samples were collected from two different contexts: These hearths were constructed in aeolian sediments with alternating clay and sand layers, indicative of fluctuating lake levels and occasional drying out.
As archaeologists used a variety of scientific dating techniques on different samples they found it a challenge to determine the age of Mungo Man. Since this bog body was once a living creature experts chose to use the absolute dating method, carbon dating.
The Minnesota Ice Man Note: This story was originally written by Rob L. As the story goes……. A man and carnie showman named Frank Hansen shot and killed a bigfoot in Minnesota in the late s. He kept it around for a while until he got into a bit of trouble trying to cross the Canadian border with it. He was actually arrested for illegally transporting a corpse human across international lines! Gerald Ford, who later became President of the USA, helped him get off of the charges and after that Hansen put the corpse in a freezer and commissioned someone to make a fake for display in sideshows and county fairs.
Retrieved Nov 25 from https: It wasn’t much of a date and consequently never published but everyone wanted to know for how much more than 40 years people had been living in Australia. New developments in numerical dating techniques are now providing answers to that question, and there is similar progress in the understanding of climate change, landscape evolution and extinction of the Late Pleistocene megafauna.
This update is based on a review Gillespie of the oldest archaeological sites from the Late Pleistocene continent of Australia, when Tasmania and New Guinea were connected to the mainland by land-bridges Figure 1. Quite a lot of the work they do is analytical chemistry, measuring the concentrations of elements and isotopes that give rise to a time-varying signal in some component of a sample.
Mungo Man is the name given to a controversial fossil of a human being found in the dry Lake Mungo in New South Wales, 90 kilometres north east of Mildura in Victoria. Mungo Man is .
Red horse head, below and to the left of the yellow horse heads. These horse heads and signs are in a small alcove, above a flat floor. Just a few lines have been used to outline more clearly the shape of a small mammoth, about 20 cm wide, taken up by the flowstone or stalagmite cascade at the entrance to the Brunel Chamber. I have highlighted the shape in the right hand photograph. The zone is heavily covered with calcite.
It is not possible to determine whether the front of this animal existed at one time. Length ca 40 cm. I had noticed in several images that the artist s used natural irregularities in the surfaces to emphasize a three-dimensional appearance.
Bradshaws now called Gwion art are among the most sophicated forms of cave painting in Australia. Introduction Australian Aboriginal rock art may be the oldest Stone Age art on the planet. This possibility is supported by the studies of Professor Stephen Oppenheimer, whose research combines genetic analysis with climatology, archeology, fossil analysis and modern dating methods, in order to juxtapose early migration with early rock art , see for example his book “Out of Eden:
The Lake Mungo remains are three sets of human fossils. They are Lake Mungo 1 (LM1, or Mungo Lady), Lake Mungo 2 (LM2), and Lake Mungo 3 (LM3, or Mungo Man). The sites are located near Lake Mungo, in New South Wales, Australia, in the World Heritage-listed Willandra Lakes Region.
Archaeological excavations by Alan Thorne at Kow Swamp, 10 km south-east of Cohuna in the central Murray Valley, between and recovered the partial skeletal remains of more than 22 individuals Thorne , , ; Thorne and Macumber google map https: While both shell and bone apatite dates are problematic Taylor , morphological and cultural comparison with well dated skeletons like Nacurrie 1 support a terminal Pleistocene date for some of the burials.
The Kow Swamp skeletons have not been published in detail, however, Thorne , ; Thorne and Macumber provides limited information on the crania, mandibles and teeth. Several years ago the Kow Swamp skeletons were reburied at the request of Aboriginal communities in northern Victoria. After 30 years the age of the Kow Swamp burials, particularly KS 9 which was the only burial excavated in situ, has recently been revisited.
Stone and Cupper report optically stimulated luminesence OSL dates for Kow Swamp which they argue are at odds with the published radiocarbon dates.

Digging in the Ganga Maya Cave in the Pilbara. The items analysed through carbon-dating techniques indicate first use of the cave from more than 45, years ago. Asked if the cave could be the site of the earliest human settlement, she said:
Lake Mungo is a dry lake located in south-eastern Australia,in the south-western portion of New South Wales. It is about km due west of Sydney and 90 km north-east of Mildura. The lake is the central feature of Mungo National Park, and is one of seventeen lakes in the World Heritage listed Willandra Lakes Region. Many important archaeological findings have been made at the lake, most.

However, sexing of the Willandra collection was very difficult, because of its generally poor and fragmentary condition.
Moreover, sexing criteria developed on Holocene skeletal collections may not be completely applicable to very different Pleistocene populations. For example, on the standard Larnach and Freedman suite of cranial features used by Webb and others to sex skulls, the gracile male WLH 3 would, in the absence of a pelvis, have been pronounced female. These further data on the gracility and robusticity of the Willandra hominids clearly demonstrate that WLH 1 is not unique, nor does she occupy a position at the extreme end of a single range of variation.

Propose deletion of the following section[ edit ] Material not notable enough to be included. The additional mutations 11 on the sequence are similar in form see in other sequence errors from the period, and also see in sequencing of ancient DNA from Mexico White Mountain, Mexico never published Was a Haplogroup M DNA with alot of derivations or sequence errors, or an ancient DNA that was contaminated by a sequencer with Haplogroup M.
The mtDNA was compared with samples taken from several other ancient Australian human skeletons, a Neanderthal mtDNA sequence, modern day living Australian Aborigines , and other living humans. The results showed that despite being anatomically within the range of fully-modern humans, LM3 was descended from a different direct maternal ancestor than the most recent common ancestor in the female line of all living humans, the so-called ” Mitochondrial Eve “.

Possibly they arrived there via the migrations of people cross land bridges or making short sea crossings from what is today SE Asia. Every time dates come back that conflict with the OOA theory suddenly a new dating technique brings them right in line with what the OOA crowd claims. Just add a few zeros or subtract a few!! These techniques placed Mungo Man as being up to 62 kyr but likely 50 kyr.
Suddenly, in the science was settled! Global warming advocates use the same term!! But there are descendants of Mungo Man alive in Australia today! How can that be a dead-end???? This specimen was dated at between Charcoal from a hearth dated these remains at These remains were poorly preserved.
