When I started reading it, I was a bit dubious, but when I read the name of the chief scientist on the project, "Dr. Jean Splicer", all doubt was removed.
While I suppose there is an off chance that there is a geneticist by the name of “Jean Splicer”, the date of the article being April 1, 2005 was the biggest clue for me.
In other April Fools news... the radio station I listen to was having listeners call in with their best April Fools jokes. The ones I liked the best were:
The mom who took the filling out of the oreos and replaced it with toothpaste, then sent it to school and work for her kids and husband.
The teacher who gave all her students scented stickers, that were scented with the odor of rotting fish.
The woman who for the last week put little piles of dirt in various places of her neighbors new lawn, and watched him from her window take various measures to rid his yard of moles, then today told the man's wife that it had been an April Fools joke in the making.
Ah, the joys of practical jokes. I haven't pulled any good ones in recent years. I'm about due for a big one. The plotting must start for next year...
