By the 1830's Adam Sedgwick and Roderick Murchison established a correlation between the various types of fossils and the rock formations in the British Isles.It was found that certain fossils, now referred to as index fossils, were restricted to a narrow zone of strata.The term can also be applied to larger groups of organisms, as in "the adaptive radiation of mammals." adaptive strategies: A mode of coping with competition or environmental conditions on an evolutionary time scale.Species adapt when succeeding generations emphasize beneficial characteristics.These flows, called the Fantastic Lava Beds, spread northeast and southwest, and dammed creeks, first creating Snag Lake on the south and then Butte Lake to the north.Butte Lake is fed by water from Snag Lake seeping through the lava beds.Nobles Emigrant Trail goes around Snag Lake and follows the edge of the lava beds.

adaptation: Any heritable characteristic of an organism that improves its ability to survive and reproduce in its environment.If we neglect to ask how the greenhouse effect of various gases is quantified in terms of real, measurable thermodynamic properties, the idea of anthropogenic global warming may well survive long enough for us to ask how the carbon budget establishes that observed increases in CO is one of the lightest volatiles (materials of relatively low melting point), found in the mantle (Wilson, 1989).The fluid nature of the aesthenosphere, or upper mantle of the earth, ensures that lighter volatiles are fractionated, buoyed towards the surface, and either extruded or outgassed into the atmosphere via volcanoes and faults.Furthermore, the discovery of a surprising number of submarine volcanoes highlights the underestimation of global volcanism and provides a loose basis for an estimate that may partly explain ocean acidification and rising atmospheric carbon dioxide levels observed last century, as well as shedding much needed light on intensified polar spring melts.

Based on this brief literature survey, we may conclude that volcanic CO is exclusively anthropogenic.Then, even if circumstances change such that it no longer provides any survival or reproductive advantage, the behavior will still tend to be exhibited -- unless it becomes positively disadvantageous in the new environment.
