It is good to keep in mind ... that nobody has ever succeeded in producing even one new species by the accumulation of micromutations. Darwin's theory of natural selection has never had any proof, yet it has been universally accepted.

We have long been seeking a different kind of evolutionary process and have now found one namely, the change within the pattern of the chromosomes. ... The neo-Darwinian theory of the geneticists is no longer tenable.

The facts of microevolution [change within the species] do not suffice for an understanding of macroevolution [theorized change from one species to another].

I have accumulated a wealth of knowledge in innumerable spheres and enjoyed it as an always ready instrument for exercising the mind and penetrating further and further. Best of all, mine has been a life of loving and being loved. What a tragedy that all this will disappear with the used-up body!
