Two human groups that differ tremendously in way of life and natural environment from other humans are the Khoi San hunter-gatherers and the pygmy foragers of sub-Saharan Africa.
Instead, Kingsley and his colleagues have long been interested in identifying regions of the human genome that differ from those of our closest animal relatives such as primates.
Clearly, studies analogous to the one we report here need to be conducted in human populations that differ in ethnicity and age from the one we investigated.
The prospective obtainment of biological samples from subjects involves an intervention with human subjects that differ in kind from the interaction that occurs with qualitative research designs (e.g., use of questionnaires, interviews, and focus group discussions), and hence, investigators might hold different perceptions regarding the need for certain ethical safeguards.
For example, zebra finches have been shown to be able to distinguish very small sound differences in words spoken by humans, including ones that differ by only one vowel.
Microarray resequencing of human mtDNA sequences that differ by << 1% from the tiled human reference approach 100% efficiency and accuracy.
Taken together, these data show that the SLX4 complex localizes at telomeres in a range of human cell lines that differ in the mechanisms used to maintain telomere length.
A recent report identified two human MBD5 transcripts that differ in the inclusion of intron 9, encoding for two protein variants of 1,448 and of 851 amino acids, respectively (Laget et al, 2010).
So far, 15 different human CAs are identified that differ in their enzymatic properties, subcellular localization, and tissue distribution.
Furthermore, there are indications that biotype 1A strains of clinical origin from human cases have characteristics that differ significantly from those that are not from human cases [ 7].
