Homo erectus Was Lazy??

A short piece in PhysOrg links to an article in PLoS that argues that, when faced with the opportunity to make Acheulean tools out of really good raw materials at a site in what is now Saudi Arabia, the local Homo erectus group took the easy way out and made them out of whatever was lying around.  From the PhysOrg piece: “New archaeological research from The Australian National University (ANU) has found that Homo erectus, an extinct species of primitive humans, went extinct in part because they were 'lazy'.”

First off, the first paragraph is nothing short of idiotic. There is absolutely no evidence whatsoever that Homo erectus went extinct because they were lazy. They colonized huge sections of Asia and were integral to the appearance of early modern humans in the area.They might have disappeared from this particular area of Saudi Arabia but that is all.  Also from PhysOrg:
"At the site we looked at there was a big rocky outcrop of quality stone just a short distance away up a small hill.

"But rather than walk up the hill they would just use whatever bits had rolled down and were lying at the bottom.

"When we looked at the rocky outcrop there were no signs of any activity, no artefacts and no quarrying of the stone.

"They knew it was there, but because they had enough adequate resources they seem to have thought, 'why bother?'".

This is in contrast to the stone tool makers of later periods, including early Homo sapiens and Neanderthals, who were climbing mountains to find good quality stone and transporting it over long distances.
Maybe this particular population was stressed in some way. Maybe the tools that they made were good enough to get done what they needed. Who knows. It is a huge inference, though, that because they didn't use the raw materials that were better that they were “lazy.”  The last sentence of the abstract reads thus:
The Acheulean hominins at Dawadmi were strong and skilful, with their adaptation evidently successful for some time. However, these biface-makers were also technologically conservative, and used least-effort strategies of resource procurement and tool transport. Ultimately, central Arabia was depopulated, likely in the face of environmental deterioration in the form of increasing aridity.
This sentence alone belies the opening, “lazy” paragraph of the PhysOrg story.  More junk journalism.

PLoS ONE Intelligent Design Paper on Grasping Hand Retracted

A paper published in the journal PLoS ONE has raised a huge ruckus with the scientific community and has led to (apparently successful) calls for its retraction.  Doug Bolton of the Independent writes:
The paper, titled: 'Biomechanical characteristics of hand coordination in grasping activities of daily living' was written by a team of four researchers, three from Huazhong University in China, and one from Worcester Polytechnic Institute in Massachusetts.

Published in the PLOS ONE journal, the fairly conventional study looked at the mechanics of how we grasp things, and involved the measurement of the hand movements of 30 participants.

However, members of the scientific community have demanded the paper be retracted, for its several perceived references to the pseudoscientific theory of intelligent design and a possibly divine 'Creator'.

In the opening sentences of the study, it claims the link between muscles and hand movements is the product of "proper design by the Creator."

Later, it says human hand coordination "should indicate the mystery of the Creator's invention," and concludes by again claiming the mechanical architecture of the hand is the result of "proper design by the Creator."
If you want a copy of this paper, you should probably hurry. It is going through the retraction process even as we speak:
“In light of the concerns identified, the PLOS ONE editors have decided to retract the article, the retraction is being processed and will be posted as soon as possible. We apologize for the errors and oversight leading to the publication of this paper.”
The authors, themselves, have retreated to the excuse that the uses of language that appear to support intelligent design were “translation errors.”

Hat Tip to Rob Mitchell.

UPDATE: There is now a retraction notice on the page that reads thus: 
Following publication, readers raised concerns about language in the article that makes references to a 'Creator', and about the overall rationale and findings of the study.

Upon receiving these concerns, the PLOS ONE editors have carried out an evaluation of the manuscript and the pre-publication process, and they sought further advice on the work from experts in the editorial board. This evaluation confirmed concerns with the scientific rationale, presentation and language, which were not adequately addressed during peer review.

Consequently, the PLOS ONE editors consider that the work cannot be relied upon and retract this publication.

The editors apologize to readers for the inappropriate language in the article and the errors during the evaluation process.

I am quite sure the Discovery Institute will weigh in at some point about this.
