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. Earth is the third planet from the Sun and the fifth largest planet in the solar system. The planet is around 4.5 billion years old, and life appeared on its surface around 3.5 billion years ago. In our universe, Earth is the only place where life is known to exist with millions of species.
