HEFEI, Dec. 8 (Xinhua) -- Chinese scientists have discovered dozens of human fossils dating back 300,000 years, which are the earliest ones found in East Asia in terms of the evolution process towards Homo sapiens, the species to which all modern human beings belong. The human fossils, alo...
The age of the Earth was determined by a) Evidence from the dating of meteorite material b) Radioactive carbon dating of fossils c) The layering of sediment in ancient soils d) Estimating the time it took to cool The earliest known fossil...
time, then used a one-tailed t-test to determine whether the mean absolute percentage error for the mcmcDivE estimate is significantly smaller than those for the other diversity estimation methods in each set of 100 simulations. We additionally computed the coefficient of determination (R2) between...
but, in this case, they offer beneficial characteristics. Iodine-131 has four extra neutrons than its stable counterpart, and has a half-life of eight days. Since iodine can be safely ingested, it is used in medicine as a form of tracer or imaging agent. Iodine-125 is also used...
