It ’s a popular defensive strategy at the bottom of the ocean : If you ’re scared , just clone yourself . The process will make you smaller and knockout to determine , as well as doubling the probability that your factor will hold up . Sand one dollar bill larvae are rampant self - cloners , but they only do it when they smell danger . That means there ’s a kind of conscious intention behind their cloning — it ’s not just an ordinary part of their reproductive cycle . How easy would it be to port this trait to humans , so we could just protrude out a new self when the old one is about to be offed ?
Probably pretty difficult , not least of which because we do n’t go through an embryo stage outside the womb .
allot to an article by Clara Moskowitz in Live Science :
Scientists exposed 4 - day - former grit dollar larvae to fish mucus , a sign that danger is closemouthed . They find that the larvae create clone of themselves within 24 hours .
“ It ’s the first time we ’ve seen anything clone itself in response to cues that predator are near , ” said researcher Dawn Vaughn , a biology doctoral bookman at the University of Washington ’s Friday Harbor Laboratories . After being exposed to fish mucus , the larvae organize embryo - similar bud that finally detach and developed into raw , genetically - very larvae that were much little than the original . The parent larvae were left small-scale , too , value about half their beginning size of it . . .
The scientists think cloning may leave a duple benefit to larvae facing peril . By doubling themselves , they have a 2nd opportunity to see their genetic information survives even if one larva gets eat .
to boot , being smaller may be good to larvae trying to hide from Pisces .
“ Pisces the Fishes are visual predators and often opt their prey base on size , ” Vaughn told LiveScience . “ You ’re apt to see something bigger . Based on past research , we ’re suppose that small size protects larvae , but we have to essay that . ”
Still , I desire my cloning powers . simulacrum via Live Science .
