After identifying variation in DC-SIGN binding capacity of breast milk derived from a group of mothers from the Netherlands, we investigated the level of variation within and between different cohorts.
As modern humans moved eastward, the level of variation decreased, reaching its minimum in the Americas.
It is rather that the level of variation existent among humans of all races today is at odds with such a possibility.
The researchers compared the level of variation in patterns of brain activity as children, adolescents and adults correctly solved math problems.
Mike Bewick, deputy medical director at NHS England, said the level of variation between practices is too wide and that the data offered an "important insight for commissioners as to where we should be doing better".
Although he developed hypotheses explaining the role of nuclein in heredity, he ultimately concluded that one molecule alone could not provide the level of variation observed in nature within and between species.
The black line is the average of 100 runs, and the 25 and 75% quartiles show the level of variation between the individual runs.
To assess the level of variation in the COI sequences, uncorrected (p) pairwise genetic distances between different haplotypes were estimated with PAUP* v4.0b10 (Swofford, 2002).
Despite the fact that the level of variation in AAC explained by our results is in agreement to the one recently evaluated in an Italian rice collection (Caffagni et al. 2013), it is consistently lower than previously observed.
However, it will be difficult to estimate the level of variation in the wind speed and, hence, the energy produced over the entire useful life of the wind energy conversion systems.
Understanding the level of variation within H. erectus is important for many reasons, one being the estimation of sexual dimorphism a trait that has major implications for how we reconstruct social and reproductive behavior.
