The discovery strengthens the bering strait land bridge hypothesis because if I remember right they did genetic analysis and her ancestors were almost certainly east asian. As for opposing migration models, they involve boats. Some evidence exists for polynesians reaching the west coast of south america, but probably in small numbers and not before humans ...

In 2013, $\large Dr.\ Liisa\ Ukkola-Vuoti,\ University\ of\ Helsinki,\ Finland$, done a detailed GWCNV(Genome-Wide Copy Number Variation Analysis) Analysis of certain group of people for musical creativity and aptitude. Genome-Wide Copy Number Variation Analysis in Extended Families and Unrelated Individuals Characterized for Musical Aptitude ...

As most of the comment have pointed it out, It's nearly impossible to find out. This is my try: Dr. L Alexander wrote in his paper, Medical Science under Dictatorship: Hitler issued the first direct order for euthanasia in Germany on September 1, 1939, as his Panzers moved on the Blitzkrieg of Poland. Organizations with humanitarian-sounding names ...

As @WYSIWYG pointed, muscular atrophy is the main cause for height decrease. A spine injury leads to neural impairment and paresis / paralysis. This affects directly muscular trophism. It also limits physical activity, this being another favoring factor for muscular atrophy and overweight issues [1]. Association of bone degenerative processes (osteoporosis, ...

Females are defined as the sex that produces that bigger gamete (ovule) while the males are those from the gender that produce the smaller gametes (spermatozoid). Because producing big gametes is costly, the number of females fix the reproductive limit in the population and in other words the variance in reproductive success in males is higher than in ...

From the wording of your question the 'genetic engineering' that you are envisaging will involve sperm. So the question is really, does vasectomy affect sperm production? The answer is that it does, but it doesn't abolish it. For example: McVicar et al. (2005) Effects of vasectomy on spermatogenesis and fertility outcome after testicular sperm ...

Rh is just a proteinous(antigenic) factor in red blood cells; not a DISEASE.If it is present in blood you are Rh positive. If not Rh negative.An Rh negative person if exposed to Rh positive blood will form specific antibodies against the Rh antigens. In case of pregnancy, Rh antigens of the foetus do not get exposed to the Rh negative blood of the mother ...

What are the evolutionary explanations for why women are weaker than men (on average), and is this difference adaptive? All of the theories surrounding this fact are speculative; it would be difficult to prove "why" men are, on average, stronger than women. One contributing theory is Female-Choice - basically that women had (or has) the ability to be ...

When you design the arrays, you need to have probes on the surface complementary to the sequence you want to detect. Depending on what you want to detect, you need to design these probes with known sequence on a known position. If you want to detect single nucleotide polymorphisms (SNP), then you need a library of known SNPs on your ChIP, which are basically ...
