New Evolutionary Research Disproves Living Missing Link Theories
Genetic research proves worm has evolved to be less sophisticated than its ancestors
Evolution is not a steady march towards ever more sophisticated beings and therefore the search for the living "missing links" is pointless, according to findings published by a team of researchers led by Dr. Herv© Philippe of the Universit© de Montr©al's Department of Biochemistry. "Aristotle was the first to classify organisms "“ from the least to the most sophisticated. Darwin's theory of evolution continued this idea, with the concept of a hierarchy of evolution. This way of thinking has led researchers and skeptics alike to look for less sophisticated ancestors in order to prove or disprove evolution," Philippe explained. "What we now know is that evolution does not happen in a single direction "“ when people talk about a missing link, they're generally excluding the possibility of more sophisticated ancestors."
"We did already know that most parasitic organisms had evolved to be less sophisticated than their ancestors "“ they lost certain abilities that they no longer needed. The independently living Xenoturbellida and Acoelomorpha do not fall in this category," Philippe said. The research is a striking example for the important role of secondary simplification in evolution and is part of 20 year project that is nearing completion. The findings were published in Nature on February 10, 2011.
