The Gulf of Mexico basin was created by an episode of crustal extension and sea-floor spreading during the Mesozoic breakup of Pangea (Salvador, 1987; Sawyer et al., 1991; Buffler and Thomas, 1994; Harry and Londono, 2004; Jacques and Clegg, 2002).
Title: Life Before Earth. Abstract: An extrapolation of the genetic complexity of organisms to earlier times suggests that life began before the Earth was formed. Life may have started from systems with single heritable elements that are functionally equivalent to a nucleotide.
Earth would be too cold for life if it had no atmosphere. The atmosphere holds enough of the sun's heat to make life possible here. Temperatures on earth range from a high of perhaps 130 degrees Fahrenheit to about -90 Fahrenheit.There are places on earth in which it is challenging for us to stay alive. There are living things in most earth environments, however.arth would be too cold for life if it had no atmosphere. The atmosphere holds enough of the sun's heat to make life possible here.
