By Justin Balding, NBC News producer Editor's note: Ann Curry's report on saving the Congo's gorillas airs tonight on the broadcast. "My director died immediately," he recalled. During his 17 years as a park ranger in eastern DR Congo's Virunga National Park, Pierre Kakule had many close calls, but none as close as the time he was riding with his boss. Their car hit a land-mine, and though Kakule survived, his forehead is still decorated with scars caused by the blast. In other instances he was involved in gun battles. And he has lost many friends and relatives. Some 120 park rangers in the last 10 years have been killed trying to keep the war-torn Virunga National Park safe from poachers and armed groups looking to make money out of killing animals. Antelopes, buffaloes and elephants are all routinely slaughtered, their "bushmeat" sold in nearby towns and villages. But most sickening of all to Kakule is the killing of gorillas. The gorilla is not just an iconic living Ancestor to him, but a part of the Human family tree nearing extiction. In the last two decades the worldwide gorilla population has been cut in half -- mainly by by deforestation and disease. In eastern Congo, the gorillas' plight is complicated by a 10-year war which has left hundreds of thousands of people displaced and desperate for money and food. Kakule says he understood the answer to Congo's conservation problem was much more ... Source: www.moreover.com --- 4 days ago

The Globe and Mail is reporting that scientists claim to have found a DNA link between the frozen remains of an aboriginal man and 17 living people. "While the work on the Human DNA project has opened new doors and work will continue on establishing a fuller family tree, Long Ago Person Found's descendants said they finally have the opportunity to give their Ancestor a proper burial. Because his lineage had never been established, no memorial potlatch could be held. Of the 17 people linked through DNA, 15 self-identify with the Wolf Clan, meaning the young man was most likely Wolf as well." Read more of this story at Slashdot. ...

New findings suggest that the ancient Human "cousin" known as the "Nutcracker Man" wasn't regularly eating anything like nuts after all. Researchers used a combination of microscopy and fractal analysis to examine marks on the teeth of members of an ancient Human Ancestor species and found that what it actually ate does not correspond with the size and shape of its teeth. This finding suggests that structure alone is not enough to predict dietary preferences and that evolutionary adaptation for eating may have been based on scarcity rather than on an animal's regular diet. ...

"..."The new find bolsters the view that Homo reached Europe not long after leaving Africa almost 2 million years ago. "It seems probable that the first European population came from the region of the Near East, the true crossroads between Africa and Eurasia, and that it was related to the first demographic expansion out of Africa," said Pares, who is a research scientist in the U-M Department of Geological Sciences and program director of the newly created National Research Center on Human Evolution (CENIEH) in Burgos, Spain, with which most of the authors are affiliated. The researchers tentatively classified the new fossil as an earlier example Homo antecessor (Pioneer Man), the species represented by the previous oldest fossils and thought to be the last common Ancestor of Neanderthals and modern humans.

There is within the Human race a need to be safely terrified - ghost stories around the campfire, scary movies, tales of horror and the supernatural - and nothing filled that need better than Tyrannosaurus rex, the king of tyrant lizards. T. rex is perhaps the largest carnivore the world has known, 43 feet long, weighing over 7 tons, the massive skulls with their chilling rictus of huge teeth. Frightening, yes, but also gone for the last 65 million years, leaving us free to fantasize about these huge beasts. Comes now disquieting news. Scientists led by Dr. John Asara of Harvard Medical School succeeded in extracting protein from a T. rex skeleton and testing the amino acids in order to create a family tree, so to speak. Alligators and T. rexes have a common Ancestor. OK. Sounds reasonable. But here's where it gets ugly. T. rex's lineal descendant is the common chicken. So this magnificent predator has been reduced to a bucket of KFC? One scientist even cruelly jibed that T. rex probably tasted like chicken. We have lost something here. Could you take seriously a "Jurassic Park"-like movie that began, "Return with us now to the Cretaceous era, when giant chickens roamed Earth"? Of course not. Or when you look at those nasty T. rex fore claws and think, "You know, I could really go for some hot wings"? Oh, the shame, the ignominy. ...

Originally posted in ct2 I've previously mentioned William Latham's mutator work. Bruce Sterling alerted me to a recent short animation by Latham that will scour your eyeballs. The film shows the evolution of a protein structure mapped into the FormGrow space traversing 20 nodes in an extrapolated phylogenetic tree covering about 50 million years (back and forth in time). The film shows a highly original representation of DNA on its journey from the Human liver to the eye lens, initially backtracking towards their common Ancestor and then moving forward to today’s time. The animated form interpolates between each node on the tree. DNA is used both to generate the forms and produce the soundtrack. The work is an extension of Latham and Todd’s ideas of the late 1980’s to the early 1990’s, where, this time, FormGrow is connected to modern genomics and proteomics. The film represents an attempt to cross the divide between scientific visualisation of DNA and aesthetically pleasing art. ... Source: sciedsociety.blogspot.com --- 12 days ago
Palentologists and Population Geneticists have discovered and confirmed that our Human ancestors originated on the dark continent. " A team of Genographic researchers and their collaborators have published the most extensive survey to date of African mitochondrial DNA ( mtDNA ). " The genetic material of the mitochondria, or powerhouse of the cell, is high conserved and has a very low mutation rate compared to nuclear or regular DNA. When sperm and egg unite, they each bring their fair share of nuclear DNA - 23 chromosomes. 22 Somatic or body chromosomes and 1 set of sex chromosomes to determine the gender of the baby. The chromosomes are the packages of ALL of your genes. Both the egg and sperm are single cells, but the egg, which is a bit larger than the sperm, also houses other cell organelles, including the mighty, mighty, mitochondria. So if you did a cheek swab, a la Maury Povich style, your mitochondrial DNA is exactly your mom's so on down the line. "Mitochondrial DNA, inherited down the maternal line, was used to discover the age of the famous 'mitochondrial Eve' in 1987. This work has since been extended to show unequivocally that the most recent common female Ancestor of everyone alive today was an African woman who lived in the past 200,000 years. Paleontology provides corroborating evidence that our species originated on this continent approximately 200,000 years ago." So this backward game of chasin ...

A new, simplified family tree of humanity has dealt a blow to those who contend that the enigmatic hominids known as Neanderthals intermingled with our forebears.
Neanderthals were a separate species to Homo sapiens, as anatomically modern humans are known, rather than offshoots of the same species, the new organigram published Sunday by the journal Nature declares.
The method, invented by evolutionary analysts in Argentina, marks a break with the conventional technique by which anthropologists chart the twists and turns of the Human odyssey.
That technique typically divides the genus Homo into various classifications according to the shape of key facial features — “flat-faced,” “protruding-faced” and so on.
Reconciling these diverse classifications from a tiny number of specimens spanning millions of years has led to lots of claims and counter-claims, as well as much confusion in the general public, about how we came to be here.
Various species of Homo have been put up for the crown of being our direct Ancestor, only to find themselves dismissed by critics as failed branches of the Homo tree.
The authors of the new study, led by Rolando Gonzalez-Jose at the Patagonian National Centre at Puerto Madryn, Argentina, say the problem with the conventional method is that, under evolution, facial traits do not appear out of the blue but result from continuous change.
So the arrival of a specimen that has some relatively ...
New York, April 27 (IANS) A new study has found why birds lack a heat-generating tissue present in mammals - and concludes that the absence of this tissue may have led to the extinction of dinosaurs. All mammals have two kinds of adipose tissue -- white and brown fat. White fat is used for storing energy-rich fuels, while brown fat generates heat. For instance, hibernating bears and Human infants have a lot of brown fat relative to their body size. This allows bears to sleep for six months and protects infants from hypothermia. Clinicians would like to find ways of making adult white fat behave more like brown fat so that we could burn, rather than store, energy. While most mammals have a key gene called UCP1, which is responsible for the heat-generation function of brown fat, birds do not. Researchers at New York Medical College found they could induce a specific type of stem cell in chicken embryos to produce differentiated cells that are structured and behave like brown fat. These chicken cells could even activate a UCP1 gene if presented with one from a mouse. The ability to produce brown fat evolved in a common Ancestor of birds and mammals, but the ability to generate heat was lost in the group that gave rise to birds and lizards after it separated from the mammalian lineage. This strongly implies that dinosaurs, which diverged from birds even later than lizards, also lacked brown fat. The paper titled 'The ...
