“The bradys must hold that, on the average, cumulative selection has to add a little information to the genome at each step. But of all the mutations studied since genetics became a science, not a single one has been found… — Lee Spetner Copy Share Image
“There is another kind of variation that does not involve the genome at all, and is therefore not heritable. Yet it can produce what… — 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
“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… — Lee Spetner Copy Share Image
“Dawkins talked about chance, but he didn’t calculate the chance of anything. Nor did he cite anyone who did. He just assumed that cumulative… — Lee Spetner Copy Share Image
“Dawkins mentioned two mechanisms: the theory of the ‘primeval soup’ and the Cairns-Smith theory. He discussed the latter in some detail. Since no one… — Lee Spetner Copy Share Image
“Dawkins’s advice shows that he didn’t understand probability. . . . Dawkins said that a creature the lives millions of years would have a… — Lee Spetner Copy Share Image
