The determination of fossils’ approximate age by comparing it with the identical fossils and rocks of familiar ages is done with the help of relative dating. On the other hand, the determination of the exact age of a fossil with the application of radiometric dating to determine the decay of isotopes, either inside the fossil or more generally the rocks related to it is done in the technique known as absolute dating.
Hunting IS NOT a form of artificial selection because it is not a form of breeding. Artificial selection refers to the intentional breeding of plants or animals. An example would be a thoroughbred racehorses, because they were selectively bred.
The cost of energy to heat water to make steam is not a
negative environmental effect of using high pressure water hoses on rocky
coastlines to clean the spilled oil. Spilled oil cause environmental pollution
to the coastlines and endangers the species the lives of the species living in
these coastlines.
