Homosexual Worm: I was created this way
Well scientist did this to the worms,, Where is the outrage!
The sexual preferences of microscopic worms have been manipulated in the
laboratory so that they are attracted to the same sex, offering new evidence
that sexuality may be hard-wired in the brain.
By activating a single gene
in the brains of hermaphrodite nematode worms, scientists have induced them to
attempt to mate with other hermaphrodites, instead of being attracted
exclusively to males.
The findings, from a team in the United States,
provide a fresh indication that homosexual or heterosexual preferences are not
purely a matter of choice, but are deeply influenced by underlying biology.
While nematode worms are extremely simpleorganisms, and details of their
behaviour are difficult to apply to people with any accuracy, the researchers
said that the existence of a biological pathway to same-sex attraction offered a
possible insight into human sexuality.
Erik Jorgensen, Professor of Biology
at the University of Utah, who led the study, said: “Our conclusions are narrow
in that they are about worms and how attraction behaviours are derived from the
same brain circuit.
But an evolutionary biologist will consider this to be a
potentially common mechanism for sexual attraction.
“We cannot say what this
means for human sexual orientation, but it raises the possibility that sexual
preference is wired in the brain. Humans are subject to evolutionary forces just
like worms. It seems possible that if sexual orientation is genetically wired in
worms, it would be in people too. Humans have free will, so the picture is more
complicated in people.”
Nematode worms, of the species Caenorhabditis
elegans, are one millimetre long and live in soil, where they feed on bacteria.
The overwhelming majority – more than 99.9 per cent – are hermaphrodites, which
produce both sperm and eggs and generally fertilise themselves before laying
eggs.
