Answer:
humans had more developed 'social' brains than Neanderthals, which enabled us to colonize new habitats and adapt to climate fluctuations
Explanation:
A more developed brain is considered to be an adaptive advantage that enabled early humans to leave Africa and colonize new habitats. Modern humans are able to adjust to new environments, situations, and socialize with other humans because the brain is a social organ. Although Neanderthals were able to occupy an important area of Europe, H. sapiens could colonize faraway lands, migrating into tropical forests, deserts, and glacial lands (colder areas than those colonized by Neanderthals). These early humans formed social groups which enabled them to find food more easily, thus greatly increasing their chances for survival.
Antibody identified in prenatal specimens is never a cause of hemolytic disease of the fetus and newborn is Anti-B.
Antibodies directed to antigens of the Lewis blood organization device. The Lewis antigens are glycoproteins which can be determined on the surface of many cells and secreted in numerous body fluids.
Anti-B may be obviously happening arising without stimulus through transfusion or being pregnant related red blood cell exposure or can be an immune stimulated antibody. In either case, it is predominantly an IgM antibody with a few related IgG element and frequently happens in affiliation with other antibodies.
Anti-E is generally an IgG antibody reactive through antiglobulin or enzyme techniques. a few examples have an IgM aspect that causes direct agglutination of E-high quality red cells. approximately of random D-wonderful bloods.
