It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.Nucleic Acid Hybridization: Widely used technique which exploits the ability of complementary sequences in single-stranded DNAs or RNAs to pair with each other to form a double helix. Hybridization can take place between two complimentary DNA sequences, between a single-stranded DNA and a complementary RNA, or between two RNA sequences. The technique is used to detect and isolate specific sequences, measure homology, or define other characteristics of one or both strands.

In epidemiology, it is used to obtain the probability of disease in a group of people with some characteristic on the basis of the overall rate of that disease and of the likelihood of that characteristic in healthy and diseased individuals. The most familiar application is in clinical decision analysis where it is used for estimating the probability of a particular diagnosis given the appearance of some symptoms or test result.Biological Evolution: The process of cumulative change over successive generations through which organisms acquire their distinguishing morphological and physiological characteristics.Fossils: Remains, impressions, or traces of animals or plants of past geological times which have been preserved in the earth's crust.Fishes: A group of cold-blooded, aquatic vertebrates having gills, fins, a cartilaginous or bony endoskeleton, and elongated bodies covered with scales.Introduced Species: Non-native organisms brought into a region, habitat, or ECOSYSTEM by human activity.Predatory Behavior: Instinctual behavior pattern in which food is obtained by killing and consuming other species.Beetles: INSECTS of the order Coleoptera, containing over 350,000 species in 150 families.

- We can see that high-throughput testing will likely go a long way to screening large numbers of chemicals, i.e. we have scalability in the many chemicals dimension, and quantitative AOPs will aid interpretation and extrapolation, but the results will initially tell us something only about a limited number of biological species. (rsc.org)
- Simply put, we think these approaches, as they currently are put together, do not have scalability in the biological species dimension. (rsc.org)
- Extrapolating quantitative AOPs across species requires the assumption that molecular pathways and functions are conserved across biological species. (rsc.org)
