'Hence, highly social bird species such as the house martin, which are subject to intense selection by parasites, have a limited scope for immediate microevolutionary response to selection because of low heritabilities, but also a limited scope for long-term response ...

... to selection because evolvability as indicated by small additive genetic coefficients of variation is weak.'

Yes I saw that. The traits in question are specifically for birds. You have traits in humans that can't be changed through environment alone in a short amount time. Hair texture is another example of this
-
Physiological traits most definitely can be. The point on birds is to show low heritabilities in traits needed for survival.
-
Depends on the trait though. Again, birds aren't humans.
-
The same is true for humans. Look at physiological traits important for vital functioning in humans, moderate to high heritability, values all over.

I'll get the cite in a bit.

Good thoughts though.
