In the first formal debate on evolution at UT in several years, biology professor Arturo De Lozanne and philosophy professor Robert Koons squared off Wednesday over whether there are weaknesses in the scientific theory.
The debate came as the State Board of Education held the last of several public hearings on whether evolution should be taught in schools as settled science or an open question.
In response to the question, “Are there weaknesses in the theory of evolution?,” Koons argued weaknesses exist because evolution is not a theory but a working hypothesis.
“Scientific theory is a set of laws that are quantifiable and testable,” Koons said. “We do not have a detailed, quantifiable model on which to testevolution. We don’t really know what evolution looks like.”
De Lozanne rebutted that scientific theories have to be overturned by better explanations, a burden which creationist philosophy cannot fulfill.
“There is no other evolution theory. The existing theory holds beautiful explanatory power based on readily available observations,” De Lozanne said. “To say we don’t understand the process of DNA mutation is a fallacy.”
The debate became heated when the argument turned to the issue of teaching evolution in schools.
Koons advocated teaching students to question the sufficiency of evolution in the classroom, arguing the dangers of foreclosing on continued debate.
“There is still a future biological Newton out there,” Koons said. “We need to inspire students to investigate the questions of evolution that still go unanswered in order to achieve a more appropriate theory.”
De Lozanne disagreed, arguing that the Texas Board of Education was using religion for their own ideological agenda.
“Religious objections to science are dangerous,” he said.
The evolution-versus-creationism debate has been a crucial dividing issue in society, with some believing that acceptance of evolution defies one’s belief in God. Sociology and pre-law senior Yi Li, who chaired the debate, spoke of the chasm between biologists and other Americans.
“The consensus among biologists differs to the belief in the population of approximately half of Americans,” she said.
Government junior Garrett Mize is director of the Texas Freedom Network student chapter, which advocates the teaching of evolution. He said discussion over evolution is important, but that he is worried it might give students the illusion that there is debate over the issue in the scientific world.
Henry R. Bose, director of the School of Biological Sciences at UT, agreed.
“There are no obvious strong weaknesses in the theory of evolution,” he said. “We live in a country where science has made a lot of progress, but education has not matched the scientific growth.”
A philosophy doctoral candidate and instructor at UT disagreed, He wished to remain anonymous out of fear that his opinion may jeopardize his position at the University.
“To object to discussion against science is intellectual bigotry,” he said.
The State Board of Education will make its decision regarding the teaching of evolution this Friday.
