One of the main contentious issues between creationists and evolutionists — how fossils were formed gradually, over millions of years, or as a result of catastrophes on a planetary scale?
The fossils that scientists find in different parts of the globe presented a wide variety of life forms ( Fig. 70 ). It and entire organisms frozen in the ice, and the bones or teeth, hardened as a result of mineralization, and insects trapped deep in the amber, and imprints of leaves or other parts of plants, bones, and animal tracks, etc. are Often preserved parts of the skeleton, but sometimes in the fossils become more and soft tissue.
The process of fossilization seems mysterious to scientists. After all, nobody has been able to reproduce it in the laboratory. Evolutionists assume that the remains of plants and animal remains appeared in different layers of the Earth as a result of a lengthy process. In the textbooks of Geology usually given the following explanation. The mineralization occurs in a gradual accumulation of salts in the tissues. Molecules of organic substances being washed away, replaced by the salts of silicon. As examples tend to be imprints of leaves and feathers of birds, formed by the indentation of objects in the soft silt, which then, after getting hard, turned to stone. It is obvious that animals,corpses have been found completely preserved in blocks of ice, died suddenly.
For a more complete understanding of the process of formation of fossils refer to the examples. It is known that all the dead in our days, living beings decompose. Sleeping fish floats on the surface of the water and gradually starts to succumb to the processes of decomposition. The corpses of the dead animals on land either eaten by predators or decompose rapidly. Dead plants are also destroyed in relatively short periods of time. Continue reading
Björn Menze of mit and Jason Ur from Harvard have developed a computerized method for the detection of ancient settlements based on satellite data and found the network of cities on the territory of modern Syria.
To search for settlements of ancient Mesopotamia on the territory of 23 thousand square kilometers archaeologists have worked in two directions at once. First, they used satellite images in different wavelength ranges to detect the so-called etrozole, – soils formed as a result of human activity and differing in color and higher content of organic substances. Data were processed automatically using a program written by one of the co-authors of the work, björn Menze, a specialist in the identification of tumors on digital images.
Secondly, the archaeologists used a bump map created in the framework of the program the Shuttle Radar Topography Mission using a radiosonde which was carried out in 2000, the Shuttle “endeavour”. Scholars interested in the place of exaltation of the landscape above the surrounding areas, what to maklovitsami about the long construction at this point. Analyzing the amount of elevation, the authors concluded that the duration of the existence of a settlement.
The resulting map contained about 14 thousands of alleged settlements that occurred in the study area over 8 thousand years. Archeologists noted that when comparing map data with the distribution of rivers and areas of heavy precipitation events, failed to detect large settlements that don’t provide sufficient water. A mismatch may affect the current view of archaeologists about the origin of irrigation, they said. Continue reading
Scientists are starting the search in the Gulf of Mexico the remains of the asteroid that killed the dinosaurs
A group of geologists proceed with installation of the drilling rig, which will be located in the Gulf of Mexico. Experts hope to find the remains of the asteroid, 65 million years ago caused the death of the dinosaurs.
This writes the online edition of Science. According to the official version, at the end of the Cretaceous period fell to Earth 10-kilometer asteroid. It is believed that he collapsed on the territory of modern South of Mexico. He left behind a 18-kilometer crater with a depth of 20 km.
She was flooded by the ocean. Scientists believe that the force of the explosion of the asteroid was comparable to the power of the explosion of hundreds of thousands of nuclear bomu capacity of 240 million megatons of TNT.
The falling asteroid caused a huge tsunami and raised a cloud of dust that hid the planet’s surface from the Sun for decades. This has led to the death of plants and animals weighing more than 25 kg.
The search will be conducted by geologists of the British geological survey and their colleagues from the United States. Underwater excavations will spend in the crater of Chicxulub, which appeared after the fall of the asteroid. Continue reading
