ACCEPTED CONCEPT. "Coevolution has been a controversial concept within evolutionary biology. While at times its role as a major factor shaping the evolution of life has been questioned, today coevolution is viewed as a powerful process generating evolutionary change." https://lnkd.in/d3gZgG7 View in LinkedIn

DIVERSITY. "Evolutionary interactions between species, and coevolution show that the complexity of genetic evolution goes on increasing, even beyond the species level. One thing is clear; the majority of the diversity of life and life forms is not just due to adaptation to static environments; biotic interactions are probably much more important. The biotic environment is itself constantly evolving, leading to orders of magnitude more diversity possible than could be produced by evolutionary adaptation to simple physical conditions." Lovely overview. https://lnkd.in/dZuwxPf View in LinkedIn

GENERATING DIVERSITY IS HARD. "The diversity of complex structures and functions in the living world is striking. The origin of new and complex structures and functions is fundamental for shaping the diversity of life. Such key innovations are rare because they require multiple interacting changes." https://lnkd.in/dgNuuqi View in LinkedIn

DIVERSITY DRIVER. "Divergent natural coevolutionary selection may be an overwhelmingly important mechanism generating diversity in nature given how different types of interactions show divergence, and how variable the putative causes generating such divergence are." https://lnkd.in/d3gZgG7 View in LinkedIn

INTERACTIVE CONSEQUENCE. "Coevolution is likely to happen when different species have close ecological interactions with one another. These ecological relationships include: Predator/prey and parasite/host. Competitive species. Mutualistic species." https://lnkd.in/dY9fCZ3 View in LinkedIn

SPATIAL SELECTION. "The Geographic Mosaic Theory of Coevolution predicts that divergent coevolutionary selection produces genetic differentiation across populations. The 29 studies reviewed here support this hypothesis as they all report spatially diverged selection trajectories which have generated variable outcomes in the interaction traits among populations." https://lnkd.in/d3gZgG7 View in LinkedIn

BIOLOGICAL ARMS RACE. "Antagonistic coevolution between hosts and parasites can drive the evolution of more complex traits by promoting arms races with increased defenses and counter-defenses." https://lnkd.in/dUUFYJe View in LinkedIn

EXTREME TRAIT GENERATION. "Dawkins and Krebs and Vermeij, have proposed that coevolutionary ‘‘arms races’’ lead to increased complexity as adaptations and counter-adaptations favor more and more extreme traits." https://lnkd.in/dUUFYJe View in LinkedIn

DEEP IMPACT. "Coevolution with parasites also had profound effects on the phylogenetic structure of host populations and on the phenotypic evolvability of host genomes." https://lnkd.in/dUUFYJe View in LinkedIn

COEVOLUTION CLASSIC. "Darwin used as a case-in-point the evolution of long-spurred flowers and long-tongued pollinators (Darwin, 1862). His logical assumption was that selection should favour spurs that are longer than the pollinator’s tongue." https://lnkd.in/d3gZgG7 View in LinkedIn
