WORLD – You know a little about DNA right?! You get your genes from your parents, but some genes aren’t inherited they jump between species. Horizontal Gene Transfer is the official name for jumping genes, but it’s not as much fun to say.
According to molecular biologists at the University of Adelaide, these jumping genes are responsible for cows possessing reptile DNA – possibly a snake. Old Bessie’s not just slightly serpent she’s 25%.
Though scientists have a name for this gene, they don’t know exactly how it jumps species; though they think a blood sucker may be involved. It’s possible the gene could have been transmitted by a tick, that bit a snake, then a cow. Their next project, whether human DNA has jumped species.
