This isn't actually true. I'll point you at my other evolutionary rant for a broader overview but here's an example. Lets say that a single gene governs homosexuality. While obviously not true, lets take that as an argument. Hypothesize that homosexuality is recessive. If you have two copies of the allele (component that makes up a gene) you are gay, if you don't have any copies you are straight and if you have one copy you are bisexual. Now if you have two copies of this allele you are totally gay and are never going to have offspring in the classic fashion. You won't even get drunk and screw someone just to see how it is and have an accident :) But let us say that the homosexual allele is linked to another trait, say efficient metabolism. People with an efficient metabolism could get by with less food and that is an evolutionary advantage when food supplies are tight. In this scenario, bisexual folks (one copy of the gay allele) are likely to have more efficient metabolisms than straight people. Not as good maybe as gay people, but better than straight folks. So even if there was a strong evolutionary penalty for being gay (having 2 copies), the allele would likely stick around in the bisexual folks because the bisexual folks have better metabolisms than straight people. And for every two bisexual people that breed, their offspring has a 25% chance of being gay and a 50% chance of being bi. And for a bi person and a straight person, the offspring have a 25% chance of being bi (still having one copy of that gene). And that's only one example of how "mother nature" can pass along genes that you'd guess might be evolutionarily maladaptive. In short, biology and evolution don't work the way you think they do...and bisexual people still have the best of all worlds :) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;207172674;29440083;f Archive: http://www.houseoffusion.com/groups/cf-community/message.cfm/messageid:280769 Subscription: http://www.houseoffusion.com/groups/cf-community/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.5
