“There is another kind of variation that does not involve the genome at all, and is therefore not heritable. Yet it can produce what looks like evolution. Indeed, the results look so much like evolution that for all we know… — Lee Spetner Copy Share Image
“Neo-Darwinians do cite some examples of evolution they claim the NDT explains. Natural selection can indeed account for the replacement of light-colored moths with dark ones when the lichens get covered with soot. But no one has shown that the… — Lee Spetner Copy Share Image

“The bradys must hold that, on the average, cumulative selection has to add a little information to the genome at each step. But of… — Lee Spetner Copy Share Image
“To understand Darwin's work, you have to distinguish between his theory of descent and his theory of natural selection. THe full name of the… — Lee Spetner Copy Share Image
“Life is so diversified that to any statement I could make about living organisms there are exceptions. Because of the many exceptions, I should… — Lee Spetner Copy Share Image
“There are many examples where species share common plastic traits. What appears to be convergence may just be the plastic response of the organism… — Lee Spetner Copy Share Image
“A mutation that reverses the effect of a previous one (called a back mutation) could at one stroke revive a complex function that had… — Lee Spetner Copy Share Image
“Only a minority of biologists today hold that the variation of evolution cannot be random. In this point the minority are on more solid… — Lee Spetner Copy Share Image
“Rather than say that the bacterium gained resistance to the antibiotic, we would be more correct to say that it lost its sensitivity to… — Lee Spetner Copy Share Image
“Common sense says that the amazing complexity of life cannot arise out of a random process. The neo-Darwinians use clever arguments to show why… — Lee Spetner Copy Share Image
