all organism evolved on earth, and all are genetically related to one another. Species living under unusual conditions might defer more than others, though. We might also predict that the more similar the percentages of naturally occurring elements are in two species, the more closely related those two species are.
Greenhouse gases are REALLY bad for the environment and one of the major cause of global warming. Greehouse gases can stay lasting in the air for 20 to 200 years.
