Scientists have turned daddy long legs into ‘daddy short legs’ by altering their genes to shrink six of their legs by half

Noted: Utilizing RNA interference, researchers at the University of Wisconsin Madison were able to sequence the genome of Phalangium opilio and modify six of the arachnids’ eight legs and turn them into half their normal size.

“We’ve shown… how the combinations of these genes create a blueprint in the embryo to differentiate between what’s going to be a leg that is used for walking and what is going to be a pedipalp, which can be used to manipulate food and assess the surroundings,” the study’s lead author, Guilherme Gainett at the University of Wisconsin-Madison, said in an interview with New Scientist.
