[What follows is an nineteenth-century defense of Lamarckism, the since-disproven belief that genetics are molded by the activity or behavior of the organism, instead of through the process of natural selection. Naturally, anyone should be cautious when reviewing a scientific article written more than a hundred year ago, but at least here below, you can see what passionate turns the debate took. In Kropotkin's favor, it may at least be said that the process of natural selection turned out to be far more complicated than Darwin and Wallace had believed, and was only fully elaborated by Dawkins as gene-centric, rather than organism or species-centric. -- Andy Carloff] There can be no doubt that species may become greatly modified through the ...

An immense variety of facts: -- adaptations of function and structure of organic beings to their surroundings; physiological and anatomical evolution; intellectual progress, and moral development itself, which we formerly used to explain by so many different causes, were embodied by...
