Carbon Dating:. Carbon dating is used to determine the age of biological artifacts up to 50, years old. This technique is widely used on recent artifacts, but teachers should note that this technique will not work on older fossils like those of the dinosaurs which are over 65 million years old. This technique is not restricted to bones; it can also be used on cloth, wood and plant fibers.

In , scientists made a startling find in a remote cave on the Indonesian island of Flores : The skull and skeleton of an adult female hominin, a group consisting of modern humans and extinct human species, who stood only about a meter tall. Instead of living 18, years ago, as they originally reported, the hobbit lived between 60, and , years ago—some 10, years before H.
That new, much older date range for H. A chief argument underpinning the diseased Homo sapiens hypothesis was the original 18,year age of the fossils—long after H. However, that 18,year-old date was based on only a geological analysis of the fossils’ surroundings and not on direct analysis of the bones themselves. And the complexity of the cave’s geology initially misled the scientists, says Matthew Tocheri, a paleoanthropologist at Lakehead University in Thunder Bay, Ontario, Canada, and a member of the discovery team.
Liang Bua is a cathedral-like cave with a high domed ceiling. The original excavations, conducted from to , dug into four regions of the cave, including a couple of sites along its eastern wall, where some fossils were found. Rather than damaging the fossils by dating them directly, the team looked to the sediments in which they were found.
They discovered pieces of charcoal in sediments at similar depths, and considered those to be proxies for the ages of the fossils themselves. The charcoal bits were dated to around 19, and 13, to 11, years before present. But Liang Bau boasts a devilishly complicated geological history, as layers of silt and clay interleave with layers of weathered limestone, loose gravel, and volcanic ash.
In many places, these layers have been scoured by erosion, altered by seeping water, and jumbled by tectonic activity.
Infections: If you have any kind of infection even if it is small such as an open cut or sore , an infection that is in your whole body such as the flu , an infection that will not go away, or a history of infections that keep coming back. ORENCIA may make your immune system less able to fight infections, so you may be more likely to get infections or any infection you have may get worse.

The evolution of whales The first thing to notice on this evogram is that hippos are the closest living relatives of whales, but they are not the ancestors of whales.
Some believed that they were the lost tribes of Israel. All whales have a number of small muscles devoted to nonexistent external ears, which are apparently a vestige of a time when they were able to move their ears – a behavior typically used by land animals for directional hearing. According to MacIver, it’s likely the first land animals started out hunting for land-based prey reactively, but over time, those that could move beyond reactive mode and think strategically would have had a greater evolutionary advantage.
