Several have been deployed in modern varieties, however, due to rapid evolution of Xoo, a number have already become ineffective.
One contributing explanation could be that cuckoos specializing on chaffinches often experience episodes of reduced fitness due to rapid evolution in the host's egg colors.
Therapeutic failure is due to rapid evolution of viral strains and accumulation of resistance-endowing mutations under selective drug pressure.
It is increasingly being accepted that, due to rapid evolution, ecological and evolutionary properties in a system change in tandem (Smallegange and Coulson 2013).
Despite the significance of the problem and consistency of the overall message, the majority of studies model interventions of limited relevance for clinicians and policymakers due to rapid evolution in the recommended standard of care to prevent paediatric infections.
Prof. Malcolm White (nominated by Dr. Purificacion Lopez-Garcia), University of St Andrews, St Andrews, Fife, UK The CRISPR system has a fundamental complexity, probably due to rapid evolution and lateral gene transfer, that can be bewildering to those not deeply steeped in the field.
Thus, the observation that has led to the assumption that the sperm are under pressure for rapid evolutionary change, which has underlain the out-of-testis hypothesis in the first place, may not be only due to rapid evolution of the sperm performing phenotype.
Phylogenetic analyses of rates of LCNS divergence reveal that the disparity between chicken/zebra finch and human/mouse appears to be due to rapid evolution of the mouse genome, but we also find an effect of slow evolution within the Reptilia, as evidenced by the short branches in that clade (fig. 4 D ).
If this is the case, these genes must have been lost after the divergence of B. fluviatilis, but it is also possible that these sequences are copies of the same ancestral sequence as the gnathostome Slc17a6 - a8, but form their own group due to rapid evolution.
For the mudstone floras at Westwater and Henrieville, the different floral composition may be due to rapid species evolution during the rise of angiosperms, the influence of climate in the mid-Cretaceous, the expression of high regional diversity of localities separated by 300 km, or a highly partitioned floodplain vegetation.
