Global urban environmental change drives adaptation in white clover.
Urbanization transforms environments in ways that alter biological evolution. We examined whether urban environmental change drives parallel evolution by sampling 110,019 white clover plants from 6169 populations in 160 cities globally. Plants were assayed for a Mendelian antiherbivore defense that also affects tolerance to abiotic stressors. Urban-rural gradients were associated with the evolution of clines in defense in 47% of cities throughout the world. Variation in the strength of clines was explained by environmental changes in drought stress and vegetation cover that varied among cities. Sequencing 2074 genomes from 26 cities revealed that the evolution of urban-rural clines was best explained by adaptive evolution, but the degree of parallel adaptation varied among cities. Our results demonstrate that urbanization leads to adaptation at a global scale

Philosophers, activists, and radicals: a story of human rights and other scandals
Paradoxically, the political success of human rights is often taken to be its philosophical failing. From US interventions to International NGOs to indigenous movements, human rights have found a place in diverse political spaces, while being applied to disparate goals and expressed in a range of practices. This heteronomy is vital to the global appeal of human rights, but for traditional moral and political philosophy it is something of a scandal. This paper is an attempt to understand and theorize human rights on the terrain of the social actors who put them to use, particularly radical activists that have a more critical relationship to human rights. Attempting to avoid the philosophical pathology of demanding that the world reflect our conception of it, we base our reflection on the ambiguous, and potentially un-patterned, texture of human rights practice—taking seriously the idea that human rights express a relationship of power, importantly concerned with its legitimate arrangement and limitation. In both the philosophical literature and human rights activism, there seems to be a consensus on basic rights as undeniable moral principles of political legitimacy. This use of human rights is contrasted with radical social movements that reject this conception of rights as ideological and illegitimate, making specific reference to the Zapatista movement (Chiapas, Mexico) and the Landless Peasant Movement of Brazil (MST, from the Portuguese Movimento dos trabalhadores rurais Sem Terra), which are critical of the human rights discourse, but also make strategic use of the idea and offer alternative articulations of political legitimacy
