Quote from: Europan Ocean
can one race be better than others?You also need to define "better". Better at what?
Some ethnic groups have genes that allow them to drink milk as adults. Is that better?
Some ethnic groups have genes that allow them to breathe air at higher altitudes. Is that better?
Some ethnic groups have genes that allow them to resist malaria. Is that better?
Some ethnic groups have genes that allow them to metabolise alcohol slower than some other groups. Is that better?
Even within these ethnic groups, these genes are not universal.
And sometimes these genes come with a downside - in one case, malaria resistance comes with a risk of a blood disease (sickle-cell anemia). Is that really better?
The reality is that different ethnic groups have inherited a set of genes that allowed them to survive in a particular environment. But in most cases it has been culture and cooperation that allowed human survival in extreme conditions, rather than genes.
One day it may be possible to select genes from multiple ethnic groups to be spliced into a child. Until then, it is merely an interesting catalogue of worldwide genetic variants.
