Studies using radiometric dating
adaptive landscape: A graph of the average fitness of a population in relation to the frequencies of genotypes in it.Peaks on the landscape correspond to genotypic frequencies at which the average fitness is high, valleys to genotypic frequencies at which the average fitness is low. adaptive logic: A behavior has adaptive logic if it tends to increase the number of offspring that an individual contributes to the next and following generations.Species adapt when succeeding generations emphasize beneficial characteristics.Because of the distortions and lies spread by fundamentalists about scientific dating there is a need for a centralized source of information on the topic.
Another standard, Oxalic Acid II was prepared when stocks of HOx 1 began to dwindle. The ratio of the activity of Oxalic acid II to 1 is 1.29330.001 (the weighted mean) (Mann, 1983). There are other secondary radiocarbon standards, the most common is ANU (Australian National University) sucrose. This is the International Radiocarbon Dating Standard.The Oxalic acid standard was made from a crop of 1955 sugar beet. The isotopic ratio of HOx I is -19.3 per mille with respect to (wrt) the PBD standard belemnite (Mann, 1983). T designation SRM 4990 C) was made from a crop of 1977 French beet molasses.The ratio of the activity of sucrose with 0.95 Ox was first measured by Polach at 1.50070.0052 (Polach, 1976b:122).The A to D categories in this list represent both the importance of each sheet, as well as the level of confidence related to its content.
