Document Summary
Newt toxin ttx resistance is highest in regions that overlap low when snakes are outside of the newt range. Camellia weevil larvae are seed predators arms race between the fruit and the weevils. European rabbits were given myxoma virus given in australia in hopes of controlling rabbit population over time, resistance evolved. Parasites sometimes manipulate the host"s behaviour to benefit the parasite people with the common cold often want to be more social parasites combat genetic drift, maintaining diversity by red queen. Coadaptation and competition bird beak sizes: overlap when they are separated, and little overlap when they are together: this eliminates competition. Host-symbiont co-diversification obligatory symbionts might be expected to match the phylogeny of the host o same topologies in a cladogram. There are many reasons why the host and symbiont might not cospeciate failure to speciate: the host speciates but the symbiont doesn"t duplication: symbiont speciates, but the host doesn"t extinction: the symbiont diversifies and then goes extinct.
