ABSTRACT FORM
... Although small populations (SP) are the forge of biodiversity [1], Haldane's dilemma completely devalues ones. The higher the number of genes under selection, the higher the death toll over a single generation. The reproductive reserve, which is, ceteris paribus, the smaller, the smaller the Ne, sho ...

Challenges to Neo- Darwinism and Their Meaning
... Randomness is a part of Darwinian theory, but it has a very definite and restricted role (lest the central premise of creativity for natural selection be compromised). It operates only in the genesis of raw material — genetic variation. It plays no role at all in the production of evolutionary chang ...
