Creationist Arguments: Anomalous Fossils

Stone Circle A common creationist claim is that humans existed alongside or predated all of their presumed ancestors in the fossil record. Taylor contains a long list of supposed examples, and Bowden discusses a number of them in more detail. Many of these cases are hominid fossils which appear in the correct position in the fossil record. Some of these are discussed elsewhere on this site: Creationists emphasize the close resemblance between these and modern human footprints, but often neglect to mention their extremely small size and the fact they may also be similar to the feet of the australopithecines living at the same time. Exactly how similar they are is a matter of some debate.

PALEONTOLOGY

Update – March 30, – new dates for Homo floresiensis! The new study dated layers of volcanic ash and calcite directly above and below the fossils. The bones of H. Homo floresiensis was one of the last early human species to die out.

Two dating techniques were used to arrive at the approximate age of the beds that make up the ground layers at Laetoli: potassium-argon dating and analysis of stratigraphy. Based on these methods, the layers have been named as follows, starting with the deepest: Lower Laetolil Beds, Upper Laetolil Beds, Lower Ndolanya Beds, Upper Ndolanya Beds, Ogol lavas, Naibadad Beds, Olpiro Beds, and Ngaloba .

Laetoli Footprint Trails The footprints of our predecessors The Laetoli footprints were most likely made by Australopithecus afarensis, an early human whose fossils were found in the same sediment layer. The entire footprint trail is almost 27 m 88 ft long and includes impressions of about 70 early human footprints. The early humans that left these prints were bipedal and had big toes in line with the rest of their foot. This means that these early human feet were more human-like than ape-like, as apes have highly divergent big toes that help them climb and grasp materials like a thumb does.

The footprints also show that the gait of these early humans was “heel-strike” the heel of the foot hits first followed by “toe-off” the toes push off at the end of the stride —the way modern humans walk. It is not until much later that early humans evolved longer legs, enabling them to walk farther, faster, and cover more territory each day. How do we know these are early human footprints? The shape of the feet, along with the length and configuration of the toes, show that the Laetoli Footprints were made by an early human, and the only known early human in the region at that time was Au.

The feet do not have the mobile big toe of apes; instead, they have an arch the bending of the sole of the foot typical of modern humans. The hominins seem to have moved in a leisurely stroll. Computer simulations based on information from A. Rainprints can be seen as well. Few footprints are superimposed, which indicates that they were rapidly covered up.

The International History Project Date: Archaeology studies past human behavior through the examination of material remains of previous human societies. These remains include the fossils preserved bones of humans, food remains, the ruins of buildings, and human artifacts—items such as tools, pottery, and jewelry. From their studies, archaeologists attempt to reconstruct past ways of life.

Archaeology is an important field of anthropology, which is the broad study of human culture and biology. Archaeologists concentrate their studies on past societies and changes in those societies over extremely long periods of time. However, archaeology is distinct from paleontology and studies only past human life. Archaeology also examines many of the same topics explored by historians.

But unlike history—the study of written records such as government archives, personal correspondence, and business documents—most of the information gathered in archaeology comes from the study of objects lying on or under the ground Archaeologists refer to the vast store of information about the human past as the archaeological record. The archeological record encompasses every area of the world that has ever been occupied by humans, as well as all of the material remains contained in those areas.

Archaeologists study the archaeological record through field surveys and excavations and through the laboratory study of collected materials. Many of the objects left behind by past human societies are not present in the archaeological record because they have disintegrated over time. The material remains that still exist after hundreds, thousands, or millions of years have survived because of favorable preservation conditions in the soil or atmosphere.

Fossil footprints challenge established theories of human evolution

Periods of the Cenozoic Era Palaeogene about In addition, the Palaeogene and Neogene periods of the Cenozoic era often are lumped together as a subera called the Tertiary. By substituting that name for those of the two periods, it is possible to use a time-honored mnemonic device by which geology students have memorized the names of the 11 Phanerozoic periods: An epoch is the fourth-largest division of geologic time and is, for the most part, the smallest one with which we will be concerned.

Newly discovered human-like footprints from Crete may put the established narrative of early human evolution to the test. The footprints are approximately million years old and were made at a.

By the beginning of this time, handaxes were made with exquisite craftsmanship, and eventually gave way to smaller, more diverse toolkits, with an emphasis on flake tools rather than larger core tools. These toolkits were established by at least , years in some parts of Africa, and by , , years in Europe and parts of western Asia.

This technique probably raised the level of standardization and predictability in stone technology. Middle Stone Age toolkits included points, which could be hafted on to shafts to make spears. Stone awls, which could have been used to perforate hides, and scrapers that were useful in preparing hide, wood, and other materials, were also typical tools of the Middle Stone Age.

These toolkits last until at least 50, to 28, years ago. In Africa, the Middle Stone Age toolkits sometimes include blades and other types of archeological evidence beads and artifacts that indicate the use of color and symbols that are typical of the Upper Paleolithic in Europe. Explore some examples of Middle Stone Age tools.

Human evolution index page see books Upright walker: About six or seven million years ago there were no bipedal creatures resembling humanity. The earth was rich with diverse life forms, all subject to and shaped by natural forces and not the slightest signs of the intelligence and creativity that typifies humanity. Planet earth flourished without humanities’ interfering nature as it had for billions of years.

God awareness had not yet emerged upon earth in any form that we can understand. As stated in the Islamic Holy Quraan, there was a time when humans did not exist. A trend toward larger brain size, a primate characteristic, started with the australopiths.

The Universe

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.

The Laetoli Footprints Explained The Laetoli footprints are fossils of footprints that look suspiciously like human footprints of today. They appear to be the fossilized footprints of two or three hominids that walked through Laetoli, Tanzania, millions of years ago. The very idea that humanoids were walking upright for as long as these fossils suggest has sparked a great deal of controversy.

Creationists typically believe that the Laetoli footprints are not millions of years old and that the footprints are not hominid, but human. Scientists tend to believe that these footprints could not have come from modern man, so it must suggest that hominids have been walking on two feet longer than previously thought. Mary Leakey was on an expedition in Tanzania with a group of other scientists when he found the Laetoli footprints.

They were there to study ancient remains, but they found something equally, if not more, interesting. The group was walking toward Olduvai Gorge together one day during their expedition. Two of the paleoanthropologists began throwing elephant dung at one another and otherwise goofing off. During the action, the Laetoli footprints were literally stumbled upon. The Laetoli footprints consist of two tracks of about 30 meters.

The first human Lucy: Johanson took the bone back to his camp and began to analyze it with colleagues. He soon realized that he had more than just a single elbow bone, but a number of bones, all from the same skeleton. Johanson returned to the site of discovery and dug up more and more bones, all of which he believed belonged to a single hominid.

He called in experts on bone structure and locomotion and then began to determine conclusions based on the findings that these experts were making. Johanson believed that Lucy, as he has come to call his skeleton, was the oldest human ancestor, at 3. Lucy was also the best preserved skeleton of a hominid, with her bones in excellent condition.

This claim was based on evidence supplied by Johanson, locomotion expert Owen Lovejoy, and many other experts in various fields, and they were well-supported and have changed the way we interpret human evolution. The most remarkable discovery about Lucy, that went along with her being bipedal, was that her brain size was very small. It was about a third of the size of humans, and much closer in size to that of apes.

August 31, , Uppsala University The footprints were discovered by Gerard Gierlinski 1st author of the study by chance when he was on holiday on Crete in Gierlinski, a paleontologist at the Polish Geological Institute specialized in footprints, identified the footprints as mammal but did not interpret them further at the time.

In he returned to the site together with Grzegorz Niedzwiedzki 2nd author , a Polish paleontologist now at Uppsala University, to study the footprints in detail. Together they came to the conclusion that the footprints were made by hominins. Andrzej Boczarowski Newly discovered human-like footprints from Crete may put the established narrative of early human evolution to the test.

The Laetoli footprints are fossils of footprints that look suspiciously like human footprints of today. They appear to be the fossilized footprints of two or three hominids that walked through Laetoli, Tanzania, millions of years ago.

The feet do not have the mobile big toe of apes; instead, they have an arch the bending of the sole of the foot typical of modern humans. The hominins seem to have moved in a leisurely stroll. Computer simulations based on information from A. S2 is represented by only 1 print, but S1 left a track of prints, the first 4 of which are shown in the composite image, along with an analysis of step and stride lengths.

Further analysis indicated that individual S1 was considerably larger than any of the three individuals from site G. Other footprints and artifacts[ edit ] Other prints show the presence of twenty different animal species besides the hominin A. Rain-prints can be seen as well. Few footprints are superimposed, which indicates that they were rapidly covered up. Most of the animals are represented by skeletal remains discovered in the area. No artifacts have been found in the vicinity, at least within the ancient Laetolil Beds that contain the trackway.

However, artifacts from the younger Olpiro and Ngaloba Beds, also preserved at Laetoli, have been found. The discovery of these footprints settled the issue, proving that the Laetoli hominins were fully bipedal long before the evolution of the modern human brain, and were bipedal close to a million years before the earliest known stone tools were made.

Australopithecus africanus — The word “Australopithecus” means “southern ape. Raymond Dart, professor of anatomy at Witwatersrand University in Johannesburg, was the first to study these fossils. In at Taung in South Africa, Dart discovered a fossil skull consisting of a full face, teeth and jaws, and an endocranial cast of the brain. The brain size was cc. Its age is currently felt to be around two to three million years old.

Dart was convinced that some teeth were man-like and thus concluded a transition between apes and man. His opinions on the matter of this particular skull were largely scorned by the scientists of this time who considered it nothing more than a young chimpanzee now considered to be about three years of age. The skull was soon known derisively as “Dart’s baby. With Piltdown Man’s human cranium and apelike jaw, it was hard to reconcile it to the Taung Child.

Although Dart gave up fossil hunting for some time, all was not lost. Years after the discovery of the “Taungs child”, as it is known today, Dart and Broom found other Australopithecines at Kromdraii, Swartkrans and Makapansgat. These finds of similar creatures seemed to vindicate Dart and Broom, and the scientific community again accepted their finds as they do today. These new fossil Australopithecines seemed to show two parallel lines of development, one being a small “gracile” slender type and the other a larger “robust” type.

Much controversy has existed regarding these types and some investigators, including Richard Leakey, have concluded that they represent merely the male and female of the same species while others say the gracile form, which is believed to be older, evolved into the robust form.
