Bubbles of methane, created by methanogens, that are present in the marsh, more commonly known as marsh gas. Marsh gas, also known as swamp gas or bog gas, is a mixture primarily of methane and smaller amounts of hydrogen sulfide, carbon dioxide, and trace phosphine that is produced naturally within some geographical marshes, swamps, and bogs.
Scientist Otto Warburg, whose research activities led to the formulation of the Warburg hypothesis for explaining the root cause of cancer.. The Warburg hypothesis (/ ˈ v ɑːr b ʊər ɡ /), sometimes known as the Warburg theory of cancer, postulates that the driver of carcinogenesis (cancer formation) is insufficient cellular respiration caused by insult (damage) to mitochondria.

Spontaneous generation is a superseded scientific theory that held that living creatures could arise from nonliving matter and that such processes were commonplace and regular. It was hypothesized that certain forms, such as fleas , could arise from inanimate matter such as dust, or that maggots could arise from dead flesh.
The pygmy mammoth is an example of insular dwarfism, a case of Foster's rule, its unusually small body size an adaptation to the limited resources of its island home.. A biological rule or biological law is a generalized law, principle, or rule of thumb formulated to describe patterns observed in living organisms.
He is also noted for his hypothesis on chordate evolution, known as Garstang's theory, which suggests an alternative route for chordate evolution from echinoderms. [ 2 ] [ 3 ] [ 4 ] The last-cited reference gives special attention to how the ideas of Garstang's predecessors profoundly influenced his biological theories.
On March 28, Hynek's swamp gas theory prompted then-Michigan Congressman (and future president) Gerald R. Ford to call for a thorough Congressional investigation of "the rash of reported sightings of unidentified flying objects in southern Michigan". [40] [41] [42] Ford issued a second release on April 3. [43]
