Since you deleted the threading references here, I cannot quote your
original msg. I recall your stating that phenotypic quality was related
to lower transcriptional error rates due to androgens, at least within
humans, between races. This is where my question (above) came from.

Instead of reacting (as is typical on this group) with anger when posed a
question, you may consider answering it. For instance, in this case, you
seem to be saying that I mis-read your post. Hence, the simple answer to
my question would be "no."

Thank you for the citations.

Thank you. How do you believe testosterone acted as a selective
pressure, approximately? If immunosuppresion is the major consideration
(instead of, say, selection pressures for muscle mass, which is mediated
by testosterone), wouldn't one expect for selection to disfavor testosterone?
