Earthworms pip humans, dinos in Most Successful 100 Species On Earth tableOctober 3rd, 2009 LONDON - Earthworms have pipped mankind and dinosaurs to emerge as the most successful 100 species on Earth in a new league table. Christopher Lloyd, the author of 'What on Earth Evolved?', examined the entire history of the planet and its life forms to determine the most successful ones.
Oldest skeleton shines new light on human originsOctober 1st, 2009 WASHINGTON - Anthropologists took the wraps off the oldest known human ancestor Thursday - a 4.4-million-year-old Ethiopian skeleton named Ardi, which challenges many long-held assumptions about how humans and apes evolved. "It's not a chimp.
Oldest-known fiber materials used by humans date back to 34,000 yearsSeptember 10th, 2009 WASHINGTON - A team of archaeologists and paleobiologists has discovered flax fibers that are more than 34,000 years old, making them the oldest fibers known to have been used by humans. The fibers were discovered during systematic excavations in a cave in the Republic of Georgia.
Song birds have to deal with cover artists tooSeptember 8th, 2009 WASHINGTON - Just like great singers among humans, birds too have to deal with cover artists who copy songs. A new research has revealed that some bird species have evolved to sing the same tune as their rivals, in order to compete effectively.
Rat as big as a cat found in extinct volcano in Papua New GuineaSeptember 7th, 2009 LONDON - An expedition team has found a new species of giant rat in an extinct volcano in the jungle of Papua New Guinea, which at 82cm length, is as big as a cat. According to a report by BBC News, the creature, which has not yet been formally described, was discovered by an expedition team filming the BBC programme 'Lost Land of the Volcano'.
Key feature of immune system survived in humans for 60 million yearsAugust 19th, 2009 WASHINGTON - A new study has concluded that one key part of the immune system survived in the humans and other primates for almost 60 million years. Researchers at the Oregon State University (OSU) and the Cedars-Sinai Medical Center in the US carried out the study.
Humans and 'hobbits' may have existed togetherAugust 4th, 2009 SYDNEY - Australian scientists have developed new theory about the 'Hobbit' species in the Indonesian island of Flores, that they existed alongside humans. Archaeologists found the 'hobbit' in 2003, while excavating in a cave on the Indonesian island of Flores.
The "hobbit" evolved separate to humansJuly 31st, 2009 SYDNEY - A new research by Australian scientists has said that the bones of the "hobbit", found in Indonesia, suggest that the species is not related to homo sapiens, and evolved separate to humans. Discovered on the Indonesian island of Flores in 2003 and dubbed 'the Hobbit', the species triggered a worldwide debate about its origins.
Human species could have killed Neanderthal manJuly 21st, 2009 WASHINGTON - The wound that killed a Neanderthal man between 50,000 and 75,000 years was most likely caused by a thrown spear, the kind modern humans used but Neanderthals did not, according to the latest research. "What we've got is a rib injury, with any number of scenarios that could explain it," said Steven Churchill, professor at Duke University.
Want something? Then talk to my right earJune 24th, 2009 LONDON - Humans prefer to be addressed in their right ear rather than their left. Current research suggests that we are more likely to perform a task when we receive the request in our right ear.
How climate change might impact species' geographic rangesJune 24th, 2009 WASHINGTON - A new study by a team of researchers has provided insights into how climate change might impact geographic ranges of species. The study, by researchers led by Jessica Hellmann, assistant professor of biological sciences at the University of Notre Dame, offers interesting insights into how species may, or may not, change their geographic range - the place where they live on earth - under climate change.
Ancient ape with human face may prove to be "missing link" speciesJune 11th, 2009 WASHINGTON - Scientists have discovered an 11.9-million-year-old fossil ape species with an unusually flat, "surprisingly human" face in Spain, a find that could prove to be the "missing link" between early human ancestors and more primitive apes. According to a report in National Geographic News, the species, Anoiapithecus brevirostris, suggests humans' ape ancestors split from primitive apes in Europe, not Africa.
Host species' extinction could make parasites jump onto alternative hostsJune 2nd, 2009 WASHINGTON - In a new study, scientists have determined that when host species go extinct, their parasites could switch onto alternative hosts which in turn could increase the rate of emerging pathogens for humans, domesticated animals and plants. The study was carried out by North Carolina State University biologist Rob Dunn and colleagues.
Where do parasites go when their hosts become extinct?June 2nd, 2009 WASHINGTON - The loss of endangered species sends alarm bells ringing among conservationists, but what happens to the parasites they host?
Although most people would side with the panda over the parasite, which group should we worry about more?
North Carolina State University (NCSU) biologist Rob Dunn and colleagues examined the concept of co-extinction, the loss of one species upon the extinction of another. "Decline in host species could drive parasite species to switch onto alternative hosts, which could escalate the rate of emerging pathogens and parasites both for humans and our domesticated animals and plants," Dunn said.
It's not a rubber ball, it's a fishFebruary 25th, 2009 WASHINGTON - Psychedelica aptly describes a species of fish that is a wild swirl of tan and peach zebra stripes and behaves in ways contrary to its brethren. Members of H.
