CSI Darwin; Laetoli Footprints Fall Completely Within the Range of Normal Human Footprints.

Humans with normal footprints?!

Whenever I accidentally stumble across CSI Miami, CSI New York or CSI Las Vegas, I eventually find myself asking; “hey, where are the detectives?!”. The crime scene investigators on these shows carry weapons, interview witnesses and arrest bad guys.

In reality, crime scene investigators or technicians collect evidence-and importantly, provide forensics; the analysis and legal interpretation of trace evidence.

When it comes to the analysis and interpretation of trace evidence, perhaps no one has done as poor a job as the Darwinists. A case in point is their interpretation of the “evidence” found and conclusions drawn with respect to the fossil named ‘Lucy”. These “technicians” found a chimpanzee like fossil which was also chimpanzee sized; then bizarrely assumed that knee bones found a few years earlier- between 1 and 2 miles distant and at lower elevation belonged to the same fossil; making it “transitional”.

Later, when human-like footprints were found in volcanic ash, which they judged to be about the same age as the fossil “Lucy”–they attributed the footprints to “her” species as well.

“Lucy” is supposed to be one of the best examples of human evolution. Darwinist’s cobbled together an imaginary being too serve as an evolutionary transition between apes/monkey’s and man. The idea was that Lucy was transitioning from tree-swinger to bi-pedalism. Among the many problems with this analysis is that the footprints have now been analyzed to show that they are completely consistent with “modern” humans or more correctly; humans.

Here’s another way to interpret your “evidence” CSI Darwin; at some time in the past there existed together; humans and chimpanzees. The knee bones found more than a mile away from the chimp did not belong to the chimp. It belonged to a human as did the footprints.

Now, go find a detective…

Evidence Indicates Humans’ Early Tree-Dwelling Ancestors Were Also Bipedal
ScienceDaily (Mar. 20, 2010)
— More than three million years ago, the ancestors of modern humans were still spending a considerable amount of their lives in trees, but something new was happening.

David Raichlen, an assistant professor in the University of Arizona School of Anthropology, and his colleagues at the University at Albany and City University of New York’s Lehman College have developed new experimental evidence indicating that these early hominins were walking with a human-like striding gait as long as 3.6 million years ago.

The results of their research appears in PLoS ONE, a journal from the Public Library of Science.

A trackway of fossil footprints preserved in volcanic ash deposited 3.6 million years ago was uncovered in Laetoli, Tanzania, more than 30 years ago. The significance of those prints for human evolution has been debated ever since. The most likely individuals to have produced these footprints, which show clear evidence of bipedalism, or walking on two legs, would have been members of the only bipedal species alive in the area at that time, Australopithecus afarensis. That species includes “Lucy,” whose skeletal remains are the most complete of any individual A. afarensis found to date.

A number of features in the hips, legs, and back of this group indicate that they would have walked on two legs while on the ground. But the curved fingers and toes as well as an upward-oriented shoulder blade provide solid evidence that Lucy and other members of her species also would have spent significant time climbing in trees.

This morphology differs distinctly from our own genus, Homo, who abandoned arboreal life around 2 million years ago and irrevocably committed to human-like bipedalism. Since the Laetoli tracks were discovered, scientists have debated whether they indicate a modern human-like mode of striding bipedalism, or a less-efficient type of crouched bipedalism more characteristic of chimpanzees whose knees and hips are bent when walking on two legs.

To resolve this, Raichlen and his colleagues devised the first biomechanical experiment explicitly designed to address this question. The team built a sand trackway in Raichlen’s motion capture lab at the UA and filmed human subjects walking across the sand. The subjects walked both with normal, erect human gaits and then with crouched, chimpanzee-like gaits. Three-dimensional models of the footprints were collected by biological anthropologist Adam Gordon using equipment brought from his Primate Evolutionary Morphology Laboratory at the University at Albany.

The researchers examined the relative depth of footprints at the heel and toe, and found that depths are about equal when made by a person walking with an erect gait. In contrast, the toe print is much deeper than the heel print when produced by a crouched gait, a product of the timing of weight transfer over the length of the foot.

“Based on previous analyses of the skeletons of Australopithecus afarensis, we expected that the Laetoli footprints would resemble those of someone walking with a bent knee, bent hip gait typical of chimpanzees, and not the striding gait normally used by modern humans,” Raichlen said. “But to our surprise, the Laetoli footprints fall completely within the range of normal human footprints.”
