He knows his line sex work sounds a bit weird. That's why, shortly after he began teaching biology at the College Park campus inhe hung a sign outside his lab that reads: Haag's research is focused on comparing Caenorhabditis elegans with Caenorhabditis briggsae, two species of worm worm developed a useful reproductive trick before they went their separate ways on the evolutionary sex pictures mature millions of years ago.

They evolved into hermaphrodites, essentially becoming modified females that can make sperm and use it with fertilize their own eggs.
