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!

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

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.

It's impossible by micro-mutation to form any new species.

The decisive step in evolution, the first step toward macroevolution, the step from one species to another, requires another evolutionary method than that of sheer accumulation of micromutations.

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.
