Furthermore, selection on parasites for countering the evolution of host egg types appears to be strong, since ashy-throated parrotbills have evolved rejection abilities for even partially mimetic eggs.
Egg rejection experiments showed that selection on parasites for countering the evolution of host egg types is evidently strong because hosts generally have evolved good abilities for rejecting even partly mimetic eggs.
Reminding students that living species are cousins rather than ancestors will help counter the misconception of evolution as linear rather than branching.
This high level of genetic polymorphism, resulting in a large number of amino-acid substitutions in all parts of the OR, strongly suggests that a large proportion of the mutations occurring during DNA replication are not counter-selected, facilitating the evolution of the OR repertoire and increasing its potential to recognise odorants.
Parasitism rates, coupled with present and future fitness costs of hosts, should determine the selection pressures acting on hosts to evolve anti-parasite adaptations, and these in turn should directly influence the evolution of counter-adaptations in their associated parasites [11], [12].
The statistical models from DoE are included in the mathematical framework of the diafiltration process, to calculate the evolution of peptide, counter-ion and solvent concentrations over time, compare constant volume vs. variable volume diafiltration modes, and select the best process in terms of operating time and solvent consumption.
This divergence in interest between the sexes results in the evolution of adaptations and counter adaptations that increase sexual dimorphisms.
For example, the paradigm of escape and radiate coevolution can be tested by looking for starbursts of speciation following the evolution of key defense and counter-defense traits.
On the other hand, specificity may actually impair the effectiveness of a biocontrol agent via the evolution of reduced virulence, host counter-adaptation through an arm race, lack of persistence in the absence of the host/prey and other ecological and evolutionary processes.
These bursts of speciation should be associated with the evolution of a novel defense or counter-defense trait.
