Human social institutions can effect the course of human evolution. Just as climate, food supply, predators, and other natural forces of selection have molded our nature, so too can our culture.

Anarchism recognises only the relative significance of ideas, institutions, and social conditions. It is, therefore not a fixed, self enclosed social system, but rather a definite trend in the historical development of mankind, which, in contrast with the intellectual guardianship of all clerical and governmental institutions, strives for the free unhindered unfolding of all the individual and social forces in life. Even freedom is only a relative, not an absolute concept, since it tends constantly to broaden its scope and to affect wider circles in manifold ways. For the Anarchist, freedom is not an abstract philosophical concept, but the vital concrete possibility for every human being to bring to full development all capacities and talents with which nature has endowed him, and turn them to social account. The less this natural development of man is interfered with by ecclesiastical or political guardianship, the more efficient and harmonious will human personality become, the more will it become the measure of the intellectual culture of the society in which it has grown.
Rudolf Rocker
Sociobiology is not just any statement that biology, genetics, and evolutionary theory have something to do with human behavior. Sociobiology is a specific theory about the nature of genetic and evolutionary input into human behavior. It rests upon the view that natural selection is a virtually omnipotent architect, constructing organisms part by part as best solutions to problems of life in local environments. It fragments organisms into “traits,” explains their existence as a set of best solutions, and argues that each trait is a product of natural selection operating “for” the form or behavior in question. Applied to humans, it must view specific behaviors (not just general potentials) as adaptations built by natural selection and rooted in genetic determinants, for natural selection is a theory of genetic change. Thus, we are presented with unproved and unprovable speculations about the adaptive and genetic basis of specific human behaviors: why some (or all) people are aggressive, xenophobic, religious, acquisitive, or homosexual.

The giraffe's neck supposedly supplies a crucial example for preferring natural selection over Lamarckism as a cause of evolution. But Darwin himself (however wrongly by later judgement) did not deny the Lamarckian principle of inheritance for characters acquired by use or lost by disuse. He regarded the Lamarckian mechanism as weak, infrequent, and entirely subsidiary to natural selection, but he accepted the validity of evolution by use and disuse. Darwin does speculate about the adaptive advantage of giraffe's necks, but he cites both natural selection and Lamarckism as probable causes of elongation.
Stephen Jay Gould
Capitalism subordinates men to machines instead of using machines to liberate men from the burden of mechanical and repetitive work. it subordinates all social activities to the imperatives of an incessant drive for individual enrichment in terms of money, instead of gearing social life to the development of rich individualities and their social relations. The contradiction between use-value and exchange-value, inherent in every commodity, fully unfolds itself in this contradictory nature of capitalist machinery. When capitalism is not overthrown once it has created the material and social preconditions for a classless society of associated producers, this contradiction implies the possibility of a steadily increasing transformation of the forces of production into forces of destruction, in the most literal sense of the word: not only forces of destruction of wealth (crises and wars), of human wealth and human happiness, but also forces of destruction of life tout court.
Ernest Mandel
[S]cientists are not robotic inducing machines that infer structures of explanation only from regularities observed in natural phenomena (assuming, as I doubt, that such a style of reasoning could ever achieve success in principle). Scientists are human beings, immersed in culture, and struggling with all the curious tools of inference that mind permits […]. Culture can potentiate as well as constrain—as Darwin's translation of Adam Smith's laissez-faire economic models into biology as the theory of natural selection. In any case, objective minds do not exist outside culture, so we must make the best of our ineluctable embedding.
