What is contamination

From a biological perspective, the spread of living organisms beyond their natural range, especially in which organisms colonize new habitats, is a “time factor” in the theory of population dynamics—the process of “natural selection.” The generalized name of the process is called seeding (seed dispersal) and is one of the key tasks of biological science in creating new agricultural plants, increasing their productivity and developing agricultural technologies.

Plants spread by wind, water (and sometimes on ice), birds, animals, or passive transfer of seeds on the paws of animals, but the mechanism of such transfer cannot explain the spread of plant seeds by paleobotanists more than 50 million years ago. Paleoecologists-botanists distinguish the so-called pedogenesis, which characterizes
