The accidental discovery of fossilized three-spine stickleback bones dating back 12 thousand years, has enabled scientist to confirm parallel evolution, or evolutionary changes or adaptions which take place repeatedly. After the ice sheets melted at the end of the last ice age around 10, to 20, years ago, there was an uplift in land, forming many coastal lakes. Threespine sticklebacks became trapped but adapted to their new freshwater habitats. This happened repeatedly across the Northern Hemisphere with freshwater sticklebacks evolving the same changes in behavior, changes in appearance and functions. This makes them an ideal 'model' to study parallel evolution.

Radiocarbon Dating of Alkenones In Sediments From The Namibian Continental Margin - NASA/ADS

Although the thought of a worldwide flood that wiped out almost all plant and animal life on earth and then buried it in the rocks may seem incredible, that is exactly what Genesis and Psalms say happened,1 what Jesus and the apostles believed 2 and what the geological evidence supports. Such a flood is also described in literature or legend in over different civilizations from around the world; however, in this short paper we will focus only on the geological evidence that points to such an event and what it means for us today. The fact that many of the same types of fossils are found all over the world, in the same order, suggests that the whole world was once under water. We say this because water is required to deposit sedimentary rocks, and because rapid burial is required to preserve fossils, and because some of the layers are the size of Nevada, and because there is virtually no evidence of time or erosion between the layers, but rather they appear to have been laid down like pancakes: one on top of the other.

Radiocarbon Dating of Sediment or Soil

A cay forms when ocean currents transport loose sediment across the surface of a reef to a depositional node, where the current slows or converges with another current, releasing its sediment load. Gradually, layers of deposited sediment build up on the reef surface. The island resulting from sediment accumulation is made up almost entirely of biogenic sediment — the skeletal remains of plants and animals — from the surrounding reef ecosystems. Cay sediments are largely composed of calcium carbonate CaCO 3 , primarily of aragonite , calcite , and high magnesium calcite. They are produced by myriad plants e.

A varve is an annual layer of sediment or sedimentary rock. The word 'varve' derives from the Swedish word varv whose meanings and connotations include 'revolution', 'in layers', and 'circle'.
