Science News

In important new science news, research into the prehistory of the human race has uncovered previously unknown physical evidence of another group of the human family of species. Though the world of science has been given over to discussion and debate over this discovery since it was announced on March 24 2010, all of this activity amongst scientific research professionals and amateur observers is due solely to a single piece of tiny physical evidence, one bone that comes from a child’s little finger. This science news began with the uncovering of the artifact by a team which searched a cave in the Altai mountain range, which is located in the southern regions of Siberia. The team of researchers came from Russia and achieved the actual discovery of the bone in 2008, in a place which is now being referred to by scientists as the Denisova cave. The analysis suggesting that this discovery might have even more ramifications for the world of science that could be determined initially by the original group of researchers came out of and were backed by the Max Planck Institute for Evolutionary Anthropology, a science institution which based out of Leipzig, Germany. The field of Science news is particularly excited by the finding made by the Max Planck Institute for Evolutionary Anthropology as to the opinion that the discovery of the Denisova child is conspicuously different in its DNA makeup from both modern day humans and from the Neanderthal species that preceded the modern day form of humans.

This science news was first publicized through a report published on the Internet through the science journal Nature. The science findings, which the researchers hasten to remind the general public and the science community should not be considered to represent conclusions, come from a procedure of extracting a kind of DNA from the bone which is referred to as mitochondrial. The studying of this data and comparison to information on other older forms of the human species suggested that the subset of primeval humans from which the owner of the bone came from migrated out of Africa independently of the two known forms of archaic humans, about one million years ago, in contrast to Homo Erectus’s departure from Africa two million years ago and the Neanderthals half a million years ago.

One possibility that could reduce the overall significance of this item of science news, though not completely in its relevance, would be the conclusion, still possible on the part of the DNA analysis researchers, that the child to which the discovered bone belonged was a member of a population derived merely from interbreeding between a known population of archaic humans and an another branch of the human family as yet undiscovered in its original state by modern day science. Though the results of testing on mitochondrial DNA may have provided the ideas about the significance of this discovery that have been so far available, conclusions from analysis of the child’s DNA are still being waited for.
