Out in the field, biologists have noted that organisms are more likely to reproduce sexually when there are more parasites loping around in their vicinity. <\/p>\n

What has been missing is a direct manipulation to organisms’ sex lives to test if it makes them more or less resistant to parasites. <\/p>\n

Direct evidence<\/span> \t <\/p>\n

Now researchers working at the University of Indiana in the US have used the round worm Caenorhabditis elegans <\/em> to do just this. <\/p>\n

The team engineered two types of worms – some that could only reproduce by having sex, and some that could only clone themselves. <\/p>\n

\"Bacterial Bacterial cells infect the crushing mouth parts of the worm and kill it<\/span> <\/div>\n

The researchers watched the worms gorge themselves on a lawn of a nasty bacterium, Serratia marcescens<\/em>, which invades the worms’ guts and from there multiplies into every crevice of their body, killing the worms from the inside. <\/p>\n

Across five different populations, worms that reproduced sexually faired well over the 20 generations, while all animals that cloned themselves died quickly. <\/p>\n<\/blockquote>\n
