Tinkering with evolution - Science

WebMar 30, 2015 · Two years later, François Jacob further expanded on some of these ideas in his influential essay ‘Evolution and Tinkering’ 2, 3. He recognized that evolution via natural selection does not work like an engineer, but like a tinkerer. Instead of redesigning its components, it tinkers by fiddling with the existing bits. WebMar 30, 2015 · To investigate regulatory element evolution, the authors identified active promoters and enhancers for each species using histone modifications as a proxy. While active promoters are enriched for methylated histone 3 (H3K4me3), active enhancers can be identified by an enrichment of acetylated histone 3 (H3K27ac; Figure 1 ). chemotherapy prioritisation score
