By combining they’re repeatable, and they from tuberculosis, a common thousands of cross-sectioned can be done without damaging disease at the time. x-ray images, CT scans let the history that we’re trying researchers examine the to understand,” Thomas says. Mummy #30007, known as the Gilded Lady, is one of the most beautifully preserved mummies from The Field Museum’s collection, and one of 19 now on view in the special exhibition Mummies. For decades, keeping mummies like this one well preserved also meant severely limiting the ability of researchers to study them. The result is that little was known about the Gilded Lady beyond what could be gleaned from the mummy’s exterior, with its intricate linen bindings, gilded headdress, and painted facial features. Exterior details do offer some clues. The mummy dates from 30 BC–AD 395, a period when Egypt was a province of the Roman Empire. While the practice of mummification endured in Egypt, it was being transformed by Roman influences. Before the Roman era, for example, mummies had been placed in wooden coffins, while the Gilded Lady is preserved in only linen wrappings and cartonnage, a papier mâché-like material. -
Place Names Describing Fossils in Oral Traditions
Place names describing fossils in oral traditions ADRIENNE MAYOR Classics Department, Stanford University, Stanford CA 94305 (e-mail: [email protected]) Abstract: Folk explanations of notable geological features, including fossils, are found around the world. Observations of fossil exposures (bones, footprints, etc.) led to place names for rivers, mountains, valleys, mounds, caves, springs, tracks, and other geological and palaeonto- logical sites. Some names describe prehistoric remains and/or refer to traditional interpretations of fossils. This paper presents case studies of fossil-related place names in ancient and modern Europe and China, and Native American examples in Canada, the United States, and Mexico. Evidence for the earliest known fossil-related place names comes from ancient Greco-Roman and Chinese literature. The earliest documented fossil-related place name in the New World was preserved in a written text by the Spanish in the sixteenth century. In many instances, fossil geonames are purely descriptive; in others, however, the mythology about a specific fossil locality survives along with the name; in still other cases the geomythology is suggested by recorded traditions about similar palaeontological phenomena. The antiquity and continuity of some fossil-related place names shows that people had observed and speculated about miner- alized traces of extinct life forms long before modern scientific investigations. Traditional place names can reveal heretofore unknown geomyths as well as new geologically-important sites. Traditional folk names for geological features in the Named fossil sites in classical antiquity landscape commonly refer to mythological or and modern Greece legendary stories that accounted for them (Vitaliano 1973). Landmarks notable for conspicuous fossils Evidence for the practice of naming specific fossil have been named descriptively or mythologically locales can be found in classical antiquity. -

These complex metazoans provided newly available niche space for viruses and microbes. Modern day contemporaries, such as cnidarians, suggest that the LCMA consisted of two cell layers: a basal endoderm and a mucus-secreting ectoderm, which formed a surface mucus layer (SML). Here we propose a model for the origin of metazoan immunity based on external and internal microbial selection mechanisms. In this model, the SML concentrated bacteria and their associated viruses (phage) through physical dynamics (that is, the slower flow fields near a diffusive boundary layer), which selected for mucin-binding capabilities. The concentration of phage within the SML provided the LCMA with an external microbial selective described by the bacteriophage adherence to mucus (BAM) model. In the BAM model, phage adhere to mucus protecting the metazoan host against invading, potentially pathogenic bacteria. -

The Carbon Cycle
The Carbon Cycle Overview of the Carbon Cycle The movement of carbon from one area to another is the basis for the carbon cycle. Carbon is important for all life on Earth. All living things are made up of carbon. Carbon is produced by both natural and human-made (anthropogenic) sources.

Fossil Record – Timing of Events and Extinction
Biology 1B—Evolution Lecture 11, Insights from the Fossil Record – timing of events and extinction Fossil Record (speciation) Microevolution Macroevolution The fossil record is our primary source of information on the past, including the timing of various extinction and evolutionary events and the phenotypes of ancestral forms. Sedimentary rocks created by erosion (often in a marine environment) form strata, with different layers corresponding to different time periods. Consider the Grand Canyon, formed by the Colorado River over 20 million years: the exposed strata, from the top of nearby Bryce Canyon to the bottom of the Grand Canyon itself, cover the last billion years. These layers can be dated by analyzing proportions of different isotopes present in each of the strata. Fossils provided both key evidence and frustration to Darwin when writing the Origin of the Species. Fossils showed there were many creatures which no longer existed; but these animals existed at some point, and must have been adapted to the environment in which they lived. This further reinforced the idea that the present and past are ruled by the same physical processes. However, it was frustrating in that many complex creatures seemed to suddenly appear in the fossil record, without preceding transitional forms. Darwin predicted that these gaps would be filled, and many of the gaps he predicted have now been filled. Some major transitions in earth history Billions of Years Ago Earth and Solar System formation 4.5 Earliest prokaryote fossils 3.5 Increase in oxygen – implies photosynthesis 2.7 Single-celled fossil eukaryotes 2.1-1.2 Complex metazoan (multi-celled animals) 0.5 Hominids (apes and humans) 0.005 The Cambrian Explosion is a time period from 550 million years ago (appearance of complex metazoans) when many species and new body forms appear in the fossil record. -

Meteorites in Ancient Times
Meteorites in Ancient Times Meteor Omens Meteorites have played many key roles throughout history and across many cultures. The observation of a meteor, or shooting star, was considered a celestial omen, switching between being a bad or good sign depending on the time and place. When Shakespeare wrote ‘The Life and Death of Richard II’ he uses a meteor to foreshadow the “death [or fall] of kings”, as the sight of a meteor was a bad omen at this time. A 147kg meteorite that fell in a wheat field outside Ensisheim (France) in 1492 was chained to the wall in a local church after the Emperor, Maximillian the First, claimed it was an ‘omen of divine protection against invasion’. Historic records of meteors are often seen in artwork and literature from the time.

Having ‘fallen from the heavens’ they often became the source of cultish worship. One meteorite holds the place of honour at Apollo’s Temple at Delphi, where the ancient Greeks believed Cronos (the god Saturn being the Roman variant) threw the rock from above after his dethronement by his son Zeus.
