D. Hamilton and others. From the gene-centred view, it follows that the more two individuals are genetically related, the more sense (at the level of the genes) it makes for them
Alternatives to evolution by natural selection Alternatives to evolution by natural selection Alternatives to evolution by natural selection, also described as non-Darwinian mechanisms of evolution, have been proposed by scholars investigating biology since classical times to explain signs of evolution and the relatedness of different groups of living things. The alternatives in question do not encompass religious points of view such as young or old earth creationism or intelligent design, but are limited to explanations proposed by biologists, though one was confusingly named 'theistic evolution' by Asa Gray. Where the fact of evolutionary change was accepted but the mechanism proposed by Charles Darwin, natural selection, was
