GENDER IDENTITY IN THE POTOMAC RIVER'S
BASS FISH AND HIS POSSIBLE RELATIONSHIP WITH THE TOXIC-METABOLIC STRESS FROM
POLLUTION OF HUMAN ORIGIN.
By Renato Cocchi.
In my previous note on homosexuality in
animals and on its possible origin <www.stress-cocchi.net/news7.htm>, I had expressed an opinion, which here follows:
"Actions of stress inside the uterus or inside the egg during a particular moment of sexual differentiation of the embryo could have better explained it, but till now there is not any confirmation."
In the meantime, about a year ago (October
2004), it became public dominion that in the South of the Potomac River, over
to increased fish pestilence, researchers observed that in a fish, the bass,
the males were producing eggs. This fact was full extraordinary and it/you was
asserted as pertaining to the waters' pollution of that river tract and its
effects on the fish. The pollution here acts ad toxic-metabolic stress even on
the sexual behaviour.
It is true that transgender individuals were
reported in many fishes. More or less gender transformation can relate to
environmental parameters. As for an example, one is the temperature, with the
well-known stressful action of cool, but even with the heat, if it does not
bring to death.
But in this event the relationship with
pollution of human origin seems new at all.
This fact isn't at odds with my previously
expressed opinion on the relationship between stress and sexual behaviour.
