The article focuses on the possible utilization of mass spectrometry (MS) in understanding fossilomics to establish how extinct and ancient species developed over millions of years. It cites an experiment of an older dinosaur fossil using MS approach wherein strict controls were employed to prevent and detect contamination. The result of the experiment suggests that dinosaurs and birds are closely related and offer evidence that collagen can be identified in an 80-million-year-old fossils.

Focuses on criticisms against an article featured in the "Journal of Chemical Education," which cast doubt on a long-standing radiometric method for dating minerals. Support of the paper's author William A. Howard for the literal interpretation of the Bible; Arguments by the author which are influenced by creationism or intelligent design; Question on the scientific validity of the paper.

The article discusses the research on the identification of the oldest rocks on Earth conducted by Jonathan O'Neal and colleagues of McGill University in Montreal, Quebec, which was published in the 2008 issue of "Science." It states that the researchers have collected samples from the Nuvvuagittuq greenstone belt in the eastern shore of Hudson Bay in Northern Quebec. Compositions of the rocks are offered. The researchers have identified the age of the rock using neodymium-based isotope dating.

The article cites a study which determined that the age of the rocks containing important imprints near Puebla, Mexico are 1.3 million years old. This study refutes a former study which concluded that humans populated the Americans 30,000 years earlier than previously believed. The researchers performed various dating methods on sediments covering the imprints.
