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.
The oldest known life on earth is approximatey 3.5 billion years old. It is likely that if any existed before this, any trace has long since been destroyed; even now, it is di â¦ fficult to research and study rocks from the period, let alone fossils or remains. 7 people found this useful.
