Human activities responsible for drastic decline in Cheetah populations

Human activities responsible for drastic decline in Cheetah populations

Human activities are responsible for the drastic decline in cheetah populations over the past many decades, according to a new study by North Carolina State University biologists.

The study, published in Journal Science, revealed that the cheetah population in Africa has decreased 10 times, from 100,000 to just 10,000 in the past century.

Genetic make-up of present-day Europeans traced

Genetic make-up of present-day Europeans traced

A new study has revealed that the modern-day Europeans gene pool is a mixture of three ancestral groups, not two.

This research was conducted by the researchers from the University of Tübingen and Harvard Medical School, along with the scientists from the Centre for Cellular and Molecular Biology (CCMB), Hyderabad.

Neanderthals were more intelligent than previously thought

Neanderthals were more intelligent than previously thought

Researchers have revealed that they have found evidence to prove that Neanderthals were considerably more sophisticated than what was previously believed by many experts. The researchers reached at the conclusion after discovering engravings deep in Gorham's Cave in Gibraltar. The discovery provided the first Neanderthal cave etchings found anywhere in the world.

Novel GPS Technique to Track Location of Human Ancestors

Novel GPS Technique to Track Location of Human Ancestors

The genetic 'sat nav', a new technique in genetics has been discovered by international team of researchers that can help learn where the human DNA was formed. The groundbreaking technique would help to determine where the ancestor's resided in the past.

Researchers at the University of Sheffield in the UK named the novel technique as the Geographic Population Structure tool (GPS). As the name resembles, the novel genetic technique can be used to find out location of past ancestors.

Americans do not believe much in Scientific Discoveries

Americans do not believe much in Scientific Discoveries

As per recent GfK Public Affairs & Corporate Communications survey, 30 percent of Americans believe that Big Bang actually happened with 51% questioning the theory. People raised their concern on the fact that universe was created 13.82 billion years ago and has been expanding rapidly ever since formation.

Survey involved online interviews of 1,012 adults with margin of sampling error of 3.4% points for all respondents. Science and Engineering Indicators Survey has been conducted for the past 34 years by the National Science Foundation.

Secret behind Easy High Altitude Adaptation of Tibetans Lies in their Genes

Secret behind Easy High Altitude Adaptation of Tibetans Lies in their Genes

A new study has unraveled the mystery behind ability of Tibetans to easily adapt to conditions at high altitudes. It was found by the study that genetic adaptations for life at high elevations originated in people related to contemporary Sherpa community about 30,000 years ago.

Population mixing attributed to transfer of these genes to more recent migrants from lower elevations. It was them amplified by the method of natural selection in the modern Tibetan gene pool.

At least 800,000-Year-Old Human Footprints Discovered

At least 800,000-Year-Old Human Footprints Discovered

In a study published in the journal PLOS One, a team of British researchers has accidentally discovered footprints on a beach of Norfolk, which as per them are the oldest human footprints in Europe.

The analysis of footprints gives an idea to researchers that they date back at least 800,000 years. They were likely made by five early humans comprising men, women and children moving to south.

Going as per the foot size, researchers have found them to be similar to those of Pioneer Man. This specie has gone extinct 600,000 years ago.

New Study Agrees to Charles Darwin’s Observation and Theories

New Study Agrees to Charles Darwin’s Observation and Theories

A new research has supported what Charles Darwin suggested through his observations and theories about animals living on islands. Darwin had said that animals living on islands are more tamer than their relatives living on the mainland. This makes the animals living on the islands more vulnerable to their predators than their counterparts living on mainland.

Caveman Diet Comprised of Tiger Nuts: Study

Caveman Diet Comprised of Tiger Nuts: Study

An array of diets can be found on internet that claims to make people more powerful and healthier. One of such diets is caveman diet. This type of diet used to prevail in the Paleolithic period and generally comprised of nuts, berries and read meat.

But a novel research carried out by a group of researchers from Oxford University has revealed that reads meat was not part of the diet at that time. Some 2.4 million years ago, people survived on tiger nuts.

Oldest Human DNA Ever Found

Oldest Human DNA Ever Found

A study has taken place by a group of researchers from the Max Planck Institute for Evolutionary Anthropology in Leipzig. The study revelation may make resaerchers to improve mankind's family tree.

The study, which has been published in the journal Nature, has found the oldest DNA, which has been found from a thigh bone in Spain that is 400,000-year-old.
