MYXOMATOSIS EXAMPLE. "The classic example is the European rabbit–myxoma virus system in which, after the virus was introduced into a naïve rabbit population, phenotypic changes were observed in both pathogen and host components of virulence. The rapid, initial attenuation of the virus presumably represents adaptation to a novel host. But subsequent slower increases in both virus pathogenicity and the ability of the host to survive infection are consistent with co-evolution." https://lnkd.in/d3-W8NW View in LinkedIn

FRAGMENT FROM NATURE for the next two weekends is on coevolution. All creatures have predators; but predation is on a spectrum of relationships that is very wide, including parasitism and symbiosis. It is probably fairer to say that all creatures have other creatures with which they interact to greater or lesser degrees. Being eaten by a lion is rather different than having athlete’s foot. But the common feature within this spectrum is how these interacting creatures coevolve. View in LinkedIn

TRANSITIONS DUE TO COEVOLUTION. "Many major events in the history of life may be attributed to reciprocal coevolutionary change, including the origin of the eukaryotic cell, the origin of plants, the evolution of coral reefs, and the formation of lichens, mycorrhizae, and rhizobia." https://lnkd.in/d3gZgG7 View in LinkedIn

Q: "Is it possible to selectively breed a code to perform selected tasks?"" "A: "Genetic programming.' https://lnkd.in/dMmdiWZ View in LinkedIn

POLLINATOR EXAMPLES. "Permanent reciprocal selective pressure between pairs of coevolving species can lead to a coevolutionary race and rapid evolutionary change. This is exemplified by spurred flowers and long-tongued flower-visitors." A lovely review. https://lnkd.in/dyf9mxs 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

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

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

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

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
