Mathematician "Shows" Life Came From 2 Different Bacteria Species
January 12, 2004 All living plants and animals are likely derived from
two primitive species of bacteria, a mathematics professor at the
University of Alberta has shown.
Dr. Peter Antonelli and a former post-doctoral student of his, Dr. Solange
Rutz, used an original mathematical modelling system and software program
to evaluate and compare the two main theories of biological evolution.
One theory, put forward by Dr. Lynn Margulis of the University of
Massachusetts, proposes that a "mother" bacteria (Bdellavibrio) and a
"father" bacteria (Thermoplasma acidophilum) "exchanged energy" in a
stable, dependable and consistent way about 3.2 billion years ago to form
all subsequent multicellular organisms, Antonelli explained.
Another theory, put forward by Dr. Carl Woese of the University of
Illinois, proposes multicellular organisms developed from many different
bacteria interacting in many different ways 3.2 billion years ago.
Research done by Antonelli and Rutz showed that Woese's theory does not
account for stability in the chemical exchange processes of many bacteria
interacting, whereas Margulis's theory holds up under the scrutiny of
Antonelli's modelling system. The study is published in the latest edition
of Nonlinear Analysis: Real World Applications.
"We showed that the chemical production necessary to support Woese's
theory is not dependable and not conducive to the formation of
multicellular organisms, but Margulis's theory proves to be reliable,"
Antonelli has also solved other problems with the 'Volterra-Hamilton'
mathematical model that he developed. He has solved the mystery of
succession in the crown of thorns population of the Great Barrier Reef.
