London, Oct 30 : An international poll has come out with varied results on one of the most debatable questions among scientists— when human life "begins" biologically?
The results come prior to a controversial constitutional amendment next week in Colorado, which will confer legal rights on embryos at the point of fertilisation.
Out of the 650 votes polled in, only 22.7pct of voters selected fertilisation as the point when human life begins.
But, detection of foetal heartbeat scored the highest, with 23.5 pct vote in its favour, and at the third position was implantation of the embryo in the womb lining with 15pct.
