Male sex chromosome on way to extinction

October 9th, 2009 LONDON - The identity of the "cursed blood" disorder that troubled the British Royal Family in the 19th and early 20th centuries has been revealed. DNA analysis show that the disease inherited by Queen Victoria's descendants was probably a severe form of the blood clotting disorder haemophilia B, according to the study published in journal Science.

October 5th, 2009 SYDNEY - A new study has determined that the world's worst mass extinction 250 million years ago was the trigger for a fungus explosion, which puts to rest the idea that an asteroid impact may have had a hand in the massive destruction. When the worldwide extinction took place, lush forests lay in ruins all across the supercontinent Pangea.

September 28th, 2009 LONDON - Experiments in stickleback fish have shown for the first time that the evolution of new sex chromosomes is the driving force behind the formation of a new vertebrate species. Up until now, most evidence has shown that new species arise because they have adapted to new environments.

August 12th, 2009 There are lots of speculation about it, it is true that though women are having a logical purpose but why do men having nipples, some thought that it is the sign of being a mammal, some believe males are failed female, all unborn creature having a tendency to be shape up as a female but due to some reason they failed to be so and turned out as male. According to medical science male breast can also produce milk and can  develop female breast diseases like breast cancer.

August 1st, 2009 WASHINGTON - A new study by paleontologists has statistically proven that new species emerge just as often as they die out, with most evolution occurring in small bursts. The study, by Luke Harmon, professor of biological sciences at the University of Idaho, who worked with a research team led by Michael Alfaro, UCLA (University of California, Los Angeles) assistant professor of ecology and evolution biology, analyzed the evolution of the 60,000 species of jawed vertebrates using genetic data.

July 17th, 2009 WASHINGTON - A new research has revealed that the sex chromosome that only males carry is deteriorating and could disappear within a few million years. Scientists at Penn State University (PSU) found that the male Y chromosome evolved at a much more rapid pace than X chromosome, which both males and females carry.

July 16th, 2009 SYDNEY - The male members of an ancient fish species known as sea dinosaurs impregnated females with penis like organs 380 million years ago, just like modern day sharks. Some fish species engaged in penetrative sex and gave birth to young ones, according to a study conducted by Curtin University of Technology (CUT).

July 15th, 2009 WASHINGTON - Rice University biologist Amy Dunham has put forward a new theory for one of primatology's long-standing mysteries-why are male and female lemurs the same size? In most primate species, males have evolved to be much larger than females, but this has not been found to be true in case of lemurs. Some theories have suggested that environment played a role or that lemur social development was altered due to the extinction of predatory birds.

July 3rd, 2009 LONDON - A British woman took a drastic step to stress the threat of extinction facing sharks worldwide by piercing her skin with giant fish hooks, and hanging herself from the ceiling of a boutique in Paris. Alice Newstead, an artist and animal rights activist, painted herself silver before piercing the skin of her shoulder blades with oversized shark fishing hooks on July 2, and then resting her feet in a harness, before she was hoisted up into the air, reports the Telegraph.

July 2nd, 2009 WASHINGTON - A new piece of research suggests that inbreeding can trigger a downward spiral of reduction among the already declining bumblebee populations. Published in the open access journal BMC Evolutionary Biology, the study has for the first time provided proof that inbreeding reduces colony fitness under natural conditions by increasing the production of reproductively inefficient 'diploid' males.

June 18th, 2009 WASHINGTON - A new research has finally proven that bones found in Shropshire, England provide the most geologically recent evidence that woolly mammoths survived in Britain until 14,000 years ago. The mammoth bones, consisting of one largely complete adult male and at least four juveniles, were first excavated in 1986, but the carbon dating which took place at the time has since been considered inaccurate.

June 5th, 2009 SYDNEY - A lizard's egg size shows whether it's going to be a boy or girl, says a new study. "We were astonished," said Richard Shine of the University of Sydney (U-S).

May 29th, 2009 WASHINGTON - Scientists at the University of Leeds in the UK have uncovered a previously unknown giant volcanic eruption that led to global mass extinction 260 million years ago. The eruption in the Emeishan province of south-west China unleashed around half a million cubic kilometers of lava, covering an area 5 times the size of Wales, and wiping out marine life around the world.

April 28th, 2009 WASHINGTON - New scientific evidence suggests that dinosaur bones from the Ojo Alamo Sandstone in the San Juan Basin, USA, date from after the mass extinction event, and that dinos may have survived in a remote area of what is now New Mexico and Colorado for up to half a million years, in a scenario resembling that of the fictional 'Lost World'. This controversial new research, is based on detailed chemical investigations of the dinosaur bones, and evidence for the age of the rocks in which they are found.

April 27th, 2009 WASHINGTON - An asteroid hit which caused the vast Chicxulub crater 65 million years ago, might not have actually wiped out the dinosaurs, along with 65 percent of all species, according to a new study. The crater, discovered in 1978 in northern Yucatan in Mexico, measuring about 180 kilometres in diameter, recorded a massive extra-terrestrial impact.
