Debate:Is the theory of macroevolution true? (view source)
Revision as of 03:58, February 21, 2007
, 03:58, February 21, 2007→Yes: point mutations are reversible. this fact is used in a standard laboratory technique
::: REPLY: It requires intelligent intervention to reverse a mutation. Lost genetic information will not be restored simply by chance.--[[User:Aschlafly|Aschlafly]] 20:52, 20 February 2007 (EST)

:::: Absolutely false. Point mutations can go either way (and frequently do). In fact, there are a number of tests which measure how mutagenic various mutagens are by using this property. Basically, you take a type of bactera which has a point mutation that leaves it unable to synthesize a necessary amino acid and then you grow a colony of that bacterium and expose them to the desired mutagen. Then you measure what fraction of the colony can survive if you remove the necessary amino acid from the medium. This sort of test has been done for about 30 years now.

Having studied and worked with scientists for a decade, and spending another decade debating armchair evolutionists, I've found that it is usually someone unsuccessful in the hard sciences (physical, chemistry, biology and you might add mathematics) who is drawn most to evolution. The late evolution-promoter Stephen Jay Gould, for example, was merely a geology major at Antioch College. Big evolution promoter Richard Dawkins was an assistant professor at Berkeley, and then a lecturer, and then it's not clear to me what his academic status was for a while. Meanwhile, real experts, such as Richard Sternberg who has TWO PhDs in evolution fields, have been critical of the theory. But Sternberg was harshly disciplined for daring to question the theory, and few are anxious to risk similar retaliation.
